It sounds like you're trying to block a virus.  Have you tried using
SpamAssassin or Clamav to block?

For comparison:

I have 5 static IP's at home, but don't host from here.  I have the same
setup at my shop where I do host.  I am using Comcast Business 2-12. 
That's 2mb up 12mb down.  It regularly performs at 5/25.  I just tested
it at 3.5/18.  It's about $75.00 per month.

This is the entry I use for no host name.  This is where it's taken some
of the load off the server.  It bans them when they try 3 or more time
from the same IP with no reverse hostname.  Postfix rejects the first
three and Fail2ban takes it from there.

I use this Fail2ban entry for failed login attempts.  It bans them after
3 attempts from the same IP.

I only measure it comparing the Logwatch SASL attempts before and after
implementing the Fail2ban.  Sorry about the lack of detail.

Postfix processes them and rejects them like this:

postfix/smtpd[15414]: NOQUEUE: reject: RCPT from unknown[64.206.88.186]:
450 4.7.1 Client host rejected: cannot find your reverse hostname,

Not sure if that's pre processing it or not.  NOQUEUE would tell me it's
not making it to the QUE.  If that's not reading too much into it.

You're correct.  Since Postfix doesn't have a Spamdyke utility I have
setup Fail2ban to basically do the same thing.  While it's not the same
it seems to do the trick.  I ban no host name, no rDNS and failed login
attempts after 3 tries for 24 hours.  It's made a measurable difference
on the load on the server.

Re: [qmailtoaster] Re: Blocking more spam

[cj yother]

  
  
Yes, you can do this and it will reduce the load on the server. 
When you're hit with a spam message that has no RDNS and they are
sending hundreds or thousands to your server it will stop them after
x attempts and ban them for x hours/days.  This will reduce the load
on Spamdyke and in turn your server.  Like you say it might not be a
lot, but it sure feels good!

  Hi folks,

   Is this a viable option please?


90% of the SPAM I am getting lately always returns

DENIED_RDNS_MISSING

or

DENIED_RDNS_RESOLVE


   In all cases the email From User is the same as the Recipient

but with prefix or postfix characters.

   Can we perhaps use this to build a script to test denied
messages

and maybe the username similarity then put the ip address in the

iptables as a "drop"?


  
  
  Given that this would not improve the effectiveness at all, but
  would only (ever so slightly) reduce the load on the server, do
  you think it'd be worth the effort? Is your host suffering from a
  heavy load?
  
  
  Also, I'd be a little concerned that these spam attempts would
  then be more difficult to measure. They could be logged before
  being dropped, but then whatever mechanism that gathers spam stats
  would have one more thing to count.
  
  
  It's not a terrible idea though. I wonder if fail2ban could be
  configured to count DENIED_RDNS messages for each IP address, and
  if there were more than a certain number of failed attempts in a
  given time period, then block the IP address.
  
  
  I'd like to hear from anyone with more familiarity with F2B than
  myself about this possibility. This might be an additional F2B
  configuration we could include.

I'll back out my changes and link to the existing guide. Sorry.

Incidentally, if it's easy to do, I'd strongly recommend making a fail2ban

I also us a no hostname filter to reduce unnecessary wear and tear. 
Works beautifully.  If you're using Spamdyke you won't need this.

Re: [qmailtoaster] re: hack attempts

I see you all are experiencing basically what I am.  I have Fail2Ban
installed with e mail notifications and that's what brought it to my
attention.  I usually see 3 or 4 attempts a day and over the past
few days it's been 30 to 40.

What helped me the most once my Fail2Ban was installed was testing
it against your log files that included attacks.  Like so.

fail2ban-regex /var/log/maillog
/etc/fail2ban/filter.d/your-filter.conf

This really nails down that's it working as desired.

Hopefully others will chime in and post a few things that will go a long 
way in helping sort out problems people are having.  I know there is

I agree and if memory serves Dovecot uses a default setting for max

number, but it's low, 10 or 20.

    # Maximum number of IMAP connections allowed for a user from

I'm not using Dovecot with QMT, but with Postfix.  If memory serves
I came across this issue before.  There is a setting in Dovecot that
regulates the amount of connections within a specific amount of
time.  You need to increase the number, turn off auto sync or
decrease frequency of Outlook checking automatically.

How often is Outlook configured to check for email?

Is Outlook configured to use IDLE? I don't recall if Outlook can use 
this capability or not.

Is there some reason you think this is a problem? I see disconnect 
messages in my dovecot log too, and have presumed that they're normal.

Anyone else have insight on this?

Agree that postfix is reliable. I am also running some EDM servers and all i need 
is a fast light-weight MTA. So my choice is postfix with dovecot. No antivirus and 
antispam. Just SPF and DKIM. Once any campaign is done, i will just shut it down to 
prevent any security breech, if there is any. With the knowledge of installing QMTs, 
postfix is much easier.

With a 2mbps dedicated bandwidth, i can send 250k emails each about 10k to my registered 
users within 4 hours.   

But I still wouldn't want to implement postfix as an enterprise email solution.

I'm sorry to say this is why I migrated to Postfix, because updating php 
breaks QMT.  Some say it's a matter of changing the php.ini file to 
allow tags since strict php tagging was implemented in php53 IIRC, but I 
was never able to get Vqadmin working properly even after their new 
release.  I don't recall having issues with Qmailadmin though.  
Hopefully Dan will chime in as I think he knows the fix.


If your colleague can open it.

1) What browser is he using?  Has he refreshed his cache?
2)Tail the access and error logs when he accesses and then when you 
access the file.  I doubt it will help, but maybe give you a clue

3)Hope someone chimes in...

Re: [qmailtoaster] Re: How to update PHP higher version without affect qmailtoaster

[cj yother]

  
  
I tried over 6 months ago to upgrade to php53 to use some of the
newer web based e mail clients.  Needless to say it wasn't happy.  I
am sure you could sort it out, but I ran out of patience, and
migrated to Postfix to accommodate.  I am not your normal user and
it is not mission critical for me, but one of the issues I see is
that in QMTs zeal to be stable it loses some of it's ability to be
on the cutting edge.

I still run 1 iteration of QMT.  It's using the .iso and IMHO that's
the best thing since sliced bread.  Pop it in and 30 minutes later
you have a fully functional QMT/Web server.   A few modifications
and off you go, safe, secure, stable.  I know you're not in favor of
keeping the .iso, but it has it's place for many.

Good luck with the CentOS 6 portion of the project.    I'm still
listening in.

Thanks to all who put in so much work to make this work.

  Hey Kahn,

First, I would try to avoid running anything other than the
hypervisor on bare iron. Run everything virtualized
underneath it.

Generally speaking, KVM performs better with newer kernels.
Older kernels use 10-20% of a cpu when idle. With newer
kernels, KVMs use <0.5% cpu when idle.

I'm not sure exactly what the change is that provides this
improvement. It appears to have happened around 3.4 in the
main kernel versions, but it also appears that RedHat (and
thus COS) has backported this change to their 2.6.32
version. BL, COS6 runs well as a KVM, but COS5 does not. I
expect that both hypervisor and guests need to be running
the improved version of the kernel to realize this
improvement.

My virtualization platform of choice is ProxmoxVE. It
provides a nice web interface for management, and has been
very reliable for me. I've used versions 2.1-3.1. While PVE
is debian based and uses .deb packages, it uses a RedHat
kernel, which give it the performance gains mentioned.

The PVE kernel also provides OpenVZ container support, as
does the web interface. While COS5 guests don't run so well
as KVMs, they run quite nicely as OpenVZ containers. I won't
go into the differences here, but running just about
anything linux based as an OpenVZ container should work ok.

I should emphasize that the point is not that running COS5
as a KVM *won't* work (it will), it's just that there's some
overhead involved that's been eliminated in more recent
kernels. In fact, I've run COS5 as KVMs in production just
fine for a period of time, on as little as a dual-core
1.6GHz machine. It's fine so long as the horsepower's
available to run it (which it quite commonly is, as I've
found most servers to be severely overbuilt).

The only thing that bothers me with PVE is that beginning
with 3.1 (which is the current release), they've introduced
a subscription based structure for their repos, sort of like
RHEL. The cost isn't excessive for small users, but it still
rubs me the wrong way. They do still provide a free repo,
but all the latest changes aren't guaranteed to be there.
We'll see how things pan out in the long run. I wouldn't be
surprised to see a COS-type counterpart to PVE spring up and
provide all of the PVE software for free, only lagging
slightly in when it's released.

I should also probably mention that I started using
virtualization with VMware S

Re: [qmailtoaster] Chef Deployment

Well you certainly make it sound easy, but when I tried I failed.  I
don't understand the cookbook concept and it's not very self
explanatory.  Glad it worked out, but I'm lost at deploy all the

  Hey List,

Just as a heads up, I have mailed a while ago that I was working on a Chef Cookbook for qmailtoaster. Since I have recently moved to a new root server, here the good news: It worked ;)

If others are curious, this is what I did:

* Deploy all cookbooks and dependencies on my Hosted Chef account
* Bootstrap the target node into my Chef Account
* Apply a qmailtoaster role to the node that includes my cookbook
* Run chef-client on the Node and wait for qmailtoaster to be installed including spamdyke
* Sync data from the old server:
 * Database Dump and User Information for vpopmail
 * /home/vpopmail/domains folder
 * /home/qmail/control folder with changes to hostnames
 * /home/qmail/users folder to fetch qmail user CDB file

And that was all. That move was painless and without issues, actually one of the best ones I had so far.

Here some restrictions though:

* I am not using any of the fronteds supplied in qmailtoaster (squirrel mail, qmailadmin etc)
 * The Chef way to install the frontend is prepared but not ready to use
* CentOS 6.4


@Eric: If you are curious, I have pushed my Chef files to Github so you (and others) can take a look: https://github.com/TheSerapher/chef-repo This does not include the cookbooks I am using but the qmailtoaster cookbook can be found here: https://github.com/TheSerapher/chef-qmailtoaster

Someday qmailtoaster will be in for some changes again, maybe we should consider wrapping it around a Chef way to install it instead of dealing with configuration changes, file adjustments and all that via RPM packages. This could even be accomplished without a Chef Server by using Chef Solo as described in my blog which I posted a while ago too. Just a few ideas, I love qmailtoaster and I will be happy with anything the list comes up with.

In that security window you can select add exception and then type

Re: [qmailtoaster] Re: cannot configure email account in Thunderbird

OK,

Try these steps to see if we can get it working

Instead of STARTTLS use SSL/TLS  port 993 and encrypted password
or
StartTLS using plain password

Go into your account settings > security > view certificates > servers 
and see that your server certificate is listed.  You can manually insert 
it using this pane, but that shouldn't be necessary.


Let me know how that works out.

Re: [qmailtoaster] CNAME Lookup failed

Dan,

I agree.  I think this is much more appropriate than changing your

changing the engine because you ran out of gas.

Try to connect to your server with an IMAP client (like

Dovecot use your vpopmail MySQL databases, but by default it uses 
Linux usernames & passwords.

I am running dovecot on my qmail toaster installation, and was

domains rather than my principle domain. I am connecting to my
IMAPS port, and notice I can't create IMAP folders on that account
either. Any thoughts where I should check? Permissions issues?


You are not alone. I suspect that issue is thunderbird related, not
toaster related. My personal observation is that I have to go into
account options on t-bird (in the copies and folders section) and
tick the other button for every message-type-handling and point it
to the correct account/inbox/corresponding folder. voilà, then it
works as advertised on the tin.


I have experienced these problems with Sent folder copying as well
(using the latest toaster + dovecot): copying to Sent folder with latest
Tbird  on Mac OSX sometimes takes very long and sometimes fails
(retrying usually works).

I have quite many domains (177, not all of them that active though) on
that server. Lately, I've been experiencing this problem several times a
week, sometimes many times a day. The I/O load on that server is quite
heavy I guess, sar reporting 10-20% average iowait during peak hours.

I'd be interested to hear if others are experiencing this and how one
could debug this Sent copying issue further?

Regards,
Peter



Are you seeing anything in the dovecot log that corresponds? I wonder 
if perhaps dovecot runs short of some resource at times during heavy 
loads.


Also, which version are people using? It would probably behoove us to 
upgrade to the current stable version. I'll make that a priority while 
working on the COS6 release, as dovecot could be released ahead of 
other things for those already using it.


This is not Qmail specific, it's possibly Dovecot.  I am running (don't 
flame me) Postfix with Dovecot and sometimes experience the same issue 
using Thunderbird.  I believe it's the amount of times Thunderbird tries 
to connect.  I haven't tracked it down completely, but when I did look 
at it, it was connections per minute.  If Thunderbird tries to check the 
mail too frequently it will ignore requests until the timer expires.

QMT is not geared toward bulk mailings. While it's fairly trivial to 
send them out, the piece that's missing is reporting of delivery and 
bouncing.


You might find some log analysis tools (analytics) which can fill that 
part. I hear that logstash is pretty nice in that regard. If that 
doesn't fit the bill, I'm sure there are others to choose from. How 
you analyze/report bounces is something you'd need to work out.


You might also look for some smtp software which specializes in bulk 
mailings.


I've used Pommo for a simple bulk mailing solution.  It worked fine for 
my application.  Bounces were just returned to the host address.  As for 
analysis, I don't recall an option for that.

Re: [qmailtoaster] Re: DNS Cache

[cj yother]

For brevity

SNIP
_3) RE: QMT and vpopmail incompatibilities with newer PHP versions:_ 
The incompatibility has been addressed in the wiki for YEARS now -- it 
is simply caused by a change in the default settings for PHP, and the 
"fix" is particularly simple (a change in /etc/php.ini). My "CentOS 6 
install script" (which I need to find time to revisit), automatically 
makes the PHP change to CentOS 6 systems, and I have at least a dozen 
sites running "stock" QMT & QMTplus installs on CentOS 6 systems. 
(NOTE: I only use 64-bit installs, so I have not tested any of my 
scripts on i686 versions of CentOS).


I am sorry CJ jumped over to Postfix, as I'm sure that was a headache 
-- just in learning a new MTA! But the PHP issue was actually minor 
(qmailadmin and admintoaster web pages didn't load properly), and was 
easily fixed.


---
I actually mis spoke, while I did have problems with PHP it was the 
segmentation faults that made me change.  Something in an update killed  
vadddomain and other functions of vpopmail which I could not resolve.  
If I had stayed away from non standard repos I would have been fine, but 
this modification killed vpopmail and adding and removing domains is 
somewhat critical to an MTA's core function.  I did read up on adding 
domains by hand, but thought that was too cumbersome.  Surprisingly 
Postfix only took me a day to setup and configure to my liking.  I 
prefer Qmail, but for the moment this works, along with my YUM updates.  
The upside, now I'm somewhat proficient in two MTA's!


So that's enough for one day... in summary:
 1) I stand by my assertions that a) QMAIL doesn't DO DNS, it USES 
DNS; b) you don't HAVE to run your own DNS resolver, but you should; 
and c) DNS issues are not QMT issues -- each admin will likely have 
their own DNS infrastructure suitable for their own situation.
 2) I don't agree that authoritative DNS and other services need to be 
on separate machines... in fact, I disagree that that is even a "best 
practice" anymore!
 3) QMT and vpopmail are fully compatible with newer PHP versions, and 
with CentOS 6... What will happen with RHEL 7 (due out in 2nd half of 
2013 or 1st half of 2014) is yet to be seen. (Will QMT officially 
support RHEL 6 before the release of RHEL 7???)


Yours in Service :-)

Always appreciated.

There is a good installation-howto for horde and centos:

Just ignore the postfix stuff (or dovecot in case you stick with the  
original courier). Worked for me.

nice,easy to install, fresh clean interface, easy to use.  I'll give
it a try for a while and see how it works.  I have been looking for a
new webmail look for a while.

I installed the outlook theme as described by Andreas, but it
doesn't quite look like the screenshot in Sourceforge.  I also have 34
themes in the them folder by default, so I had to make it [35].  
 Nutsmail looks like the cleanest, most modern looking option to me,
but that's just my .02

What other webmail interfaces are people using?  I have had
squirrelmail running for several years on a toaster, but am building a
new toaster and want a new interface.  I think the final straw was my
65 year old mother telling me it looked dated and that she
didn’t like using it.  Roundcube looks promising, but am
wondering just how far along it is, Horde looks like a pain, and then
there are a myriad of others.  I wish SM would change the look,
because it works well - something a little more Outlookish would be
great, but I don’t think they ever plan that.  Just need some
hints, and something that is easy to install and maintain.  
 Roundcube has had several major security flaws in the past that
allowed persistent crackers to obtain shell access on a server.  I do
not recommend it anymore as I have lost trust in the code base at this
point. Mine is not the only opinion, but if you do go with it I would
recommend trolling their forums every other day to keep up on
vulnerabilities.
 There are some skins for Squirrelmail that others have suggested.
I've personally used Nutsmail (nustmail.com) with it and it worked
well.
 Horde is a little bit of setup, and I think it's interface is kludgy,
but it does provide a little more functionality.
 eGroupware is a little cleaner and provides a lot of extra
functionality, but I have not set it up for Qmail yet myself. 
 Someone else sent me a link a while back for another one that was
perl based that looked different, but I did not test it out much.
 How about we keep this thread going and add links to the reply, so we
have one lone list of webmail apps to try out. I'll start it:
