Postfix support for TLS goes way back.

Please see the Red Hat backports policy at:
https://access.redhat.com/security/updates/backporting/

OpenSSL in CentOS 7 is fine, I would not change or mess with it as it's
an integral part of the distribution.

Postfix is fine as well and there is no lack of TLS support in the
Postfix 2.10.1.  That said, you can get a newer postfix for CentOS 7
from GhettoForge:
http://ghettoforge.org/index.php/postfix3

Postfix bounces mail when the Delivered-To address is the same as
the current recipient.

The easiest explanation is that you are accepting mail for the old
domain, then forwarding it through outlook back to the new domain.
Or something similar.

To log all headers, use a header_check like:
/./  info

NOTE: postfix only allows one header_check rule per header, so this
will disable any header_checks below it.  Usually people put a
log-all rule like this at the end of header_checks file.

Test; don't speculate.  As a bystander, my job it to speculate: I
don't think outlook is adding the offending headers.

TLS does not materially affect the performance of bulk-email delivery except
when a high-volume destination's MX host set includes some hosts that are
down.  When one of the MX hosts is down and you don't use TLS,  connection
re-use will shift more of the load to the hosts that are up.  With TLS there
is no connection re-use, and so connection latency may rise if the remote
destination is partly down.  This is rare in practice for high-volume
destinations.

Postfix TLS support is reasonably mature by Postfix 2.8, but older versions
should also be fine.  Just set:

smtp_tls_protocols = !SSLv2, !SSLv3
smtp_tls_ciphers = medium
smtp_tls_security_level = may
smtp_tls_loglevel = 1

smtpd_tls_protocols = !SSLv2, !SSLv3
smtpd_tls_ciphers = medium
smtpd_tls_security_level = may
smtpd_tls_loglevel = 1
smtpd_tls_cert_file = ... your cert file location ...
smtpd_tls_key_file  = ... your key file location if different from cert 
file ...

if these are not already the defaults for your Postfix version.

So I created the following entry in my header_checks file:

  /^Delivered-To:/ WARN Found email with Delivered-To: header already in it!

And while it did correctly warn on a bogus email that matched with
looping, it also matched on a bunch of other emails, which didn't get
rejected for looping.

So I'm wondering if the problem is that I'm not accepting email for my
legacy "foo.com" domain properly, while I am accepting email for my
"foo.bar.com" domain that we're now supposed to be using for all
email.

I'm glad I just did a warning match at first, instead of holding all
these emails, because it would have been a disaster for a bit until I
figured it out.  Is there anyway, besides the hold queue to just log
all the headers of these messages so I can try to understand the issue
in more detail?  I suspect that part of the problem is that we use
this server for outgoing emails, but all incoming from the internet
arrives through *.outbound.protection.outlook.com, so maybe they do
something to the headers?

My logs show the following:

Postfix for bulk email and TLS

2017-03-31 Thread Xinhuan Zheng 
Hello,

Does anyone in postfix mailing list have experience using Postifx software for 
sending bulk emails with TLS encryption? Can you share your experience with me? 
The amount of bulk email is quite large, normally for marketing purpose. In the 
past we have been using sendmail bundled with CentOS 6 OS for a few years 
already. But we need to upgrade our system and one new requirement is to use 
TLS. So I’m planning on using recent CentOS 7 operating system. But as I look 
at its repository, postfix and openssl appear to be old versions.
Thanks,

It seems it is sending emails to a domain's A record when no MX is found.

Is that standard? If so, can i disable this somewhere?

It's a temporary failure on top of that, left to linger in the queue til

As I see here header_checks can do it. There is only one problem. This rule
searching for a subject with string [MASSMAIL] and replacing complete

/^Subject:.*[MASSMAIL].*/ REPLACE Subject: test


How to replace only single string [MAILMAN] without interrupting the rest
of the subject ?


Subject: [MASSMAIL] test message blablabla

/^Subject:.*[MASSMAIL].*/ REPLACE Subject: test

Its replacing to
Subject: test


How to replace that string to:

Maybe some one knows ?

This list (postfix-users) is so configured that when I`m clicking Reply on
Your answer, system sending message to directly to you instead of the list.
On mobile device some times its difficult. It was not my intention to write
an E-mail directly to You... I prefer list.

Mailman is connected as usual with Postfix. So its forwarding messages
directly to Postfix and Postfix sending it to another relay.
Its quite diffucult for me because on that host I have 180 mailing lists
with ~5mln users. [MAILMAN] prefix is only on few of them and i`m searching
for some fast solution.

Thats why I`m here... On Postfix-users list. I also opened Topic on mailman
list.

Maybe somebody else knows how to monipulate Subject with Postfix ?


Thanks in advance for any help.


Cheers

Zalezny

Re: how to remove string "[MASSMAIL]" from the subject ?

2017-03-31 Thread Larry Stone 
Neither do I as you have provided no information about your Postfix 
configuration or anything else. As it says in the Postfix list welcome email 
you received:
TO REPORT A PROBLEM see http://www.postfix.org/DEBUG_README.html#mail
But if you’ve verified Mailman is not adding it as a list prefix tag, then you 
need to tell us what else is handling the email before it makes it to your 
mailbox. 

Also, reply on list, not directly to me. Future emails sent directly to me will 
be ignored.

Re: how to remove string "[MASSMAIL]" from the subject ?

2017-03-31 Thread Larry Stone 
This is a Mailman mailing list you run? That Mailman has the option to add a 
tag in front of the subject (and it’s not the default so you would have had to 
explicitly turn it on). There is a Mailman-users mailing list and that would be 
the appropriate place for help.

But, since it says [MASSMAIL] and MASS implies to me that it’s to indicate that 
it’s being sent to a MASS of recipients, it sounds like it might be a mail 
filter downline of Mailman that, for instance, sees the “Precedence: bulk” 
header and tags the mail. In which case Mailman has nothing to do with it.

In any event, the [MASSMAIL] tag is a symptom of some other problem adding the 
undesired (to you at least) tag. Fix the problem, not the symptom.

how to remove string "[MASSMAIL]" from the subject ?

2017-03-31 Thread Zalezny Niezalezny 
Hi,

will it be possible to remove string [MASSMAIL] from outgoing E-mails ?


From: bla!@firma.com
to: *@gmail.com
Subject: [MASSMAIL] text of the messages

I would like to have some thing like this.

From: bla!@firma.com
to: *@gmail.com
Subject: text of the messages


Unfortunatelly Mailman adding this string to some of my mailing lists and I
do not know how to change it, maybe it will be possible to rewrite it with
Postfix ?



Thanks in advance for any support.

Unfortunately not. There was no load on the system. It is standard rsyslog.

Yes and they also always log to syslog on connect/discconect and processing 
mails.

There have been very few mails at that time. That is what makes me wonder. No 
load could have caused this issue.

I personally wonder how many people make use of that new feature 
smtpd_milters_maps and maybe nobody else discovered this issue though.

Maybe I need to figure out how to do a test on sending mail from my relay 
server, while simultaneously sending mail from remote and watching. I think 
that should trigger the problem again, if I am right. Let's see what I can do 
here.
