Subject: Fetchmail posts two copies of each mail... ?

Reply-To: Matthew <[EMAIL PROTECTED]>
Hello,
I am using fetchmail to retrieve mail from an ISP to a mail gateway
machine running RedHat Linux 5.1 and sendmail 8.8.7 (sendmail.cf 8.8.4). I
don't think that sendmail is the problem though...
The mail is posted into a multidrop box at the isp (any mail that goes to
mydomain.co.uk). My machine is locally called gateway.mydomain.co.uk (and
other machines on the network are called a.mydomain.co.uk, b.mydom..., c.
etc.)
I have to use POP3 to retrieve the mail, but with fetchmail it gets the
mail from the ISP, and then depending on how I change the .fetchmailrc
file either sends it all to [EMAIL PROTECTED], or to, say,
[EMAIL PROTECTED] *and* [EMAIL PROTECTED] Sendmail then
reports a problem because the MX dns entry points gateway.mydomain.co.uk
to mydomain.co.uk and reports a DNS loop, bouncing one of the two e-mails
back to the sender.
I could use the first method of all e-mail going to root, and then use
procmail to separate e-mail out to each user (which seems to allow more
dynamic configuration), but then the users cannot use "Reply" to reply
e-mail back to the sender, as the sender of the mail is now "root".
Please help! I don't really mind which method I use to retrieve the mail,
but it really needs to put the e-mails into local (mail gateway) mailboxes
unaltered from downloading from the ISP.
Thanks,
Matthew

O.K. Sorry...
Try this http://www.slac.stanford.edu/cgi-bin/nph-traceroute.pl
Don't suppose you know of an answer to my question a few posts back today.
Have been waiting most of the afternoon for someone to give a suggestion.

Richard,
What are using for the Firewall/Forwarding control; IPFWADM or IPChains? I'm
really struggling with IPFWADM and would appreciate an editted version of
your IPFWADM statements -- if you don't mind.

You have to decide how ou want them to log on-- whetehr with PAP or CHAP
(better) or login. If with PAP or CHAP use AutoPPP in
/etc/mgetty*/login.config.

Fine. Use either the login authentication or CHAP. In the latter case
you have to set up the chap-secrets file with a line for each user ( and
use the require-chap option to pppd).
In the former you need to use the noauth and tell the users to run pppd
when they have logged on.

Linux Standalone Machines?

Went looking for you to maybe find some good source of information for
you... Couldn't find anything other then a reference to using Samba on the
Linux Machine to allow communication with other Win machines.
When deciding on a solution or path the amount of information you find on
the subject can be a really good hint on the direction you should take.
I personally havn't used the peer to peer method in several years and that
was with AppleTalk.
If you are looking for simplisity then stick as closly as possible to common
standards.
A simple hub & "star" configuration is easy to set up, easy to maintain,
easy to upgrade, and can be done at a on a very tight budget.
Don't worry about the client server stuff. If you move to all linux then
Linux works very well with tcp/ip. There is plenty of information and you
can add new services when you are ready without much hassle.
Another big benefit of this is not being as slow as your slowest link and
the ability to upgrade piece by piece. You can upgrade a hub without
upgrading all of the clients. Then upgrade the clients when you get around
to it. You can service a client without stopping production on all of your
clients.
In the future if you want a dedicated server... Plug it in.
Don't get lost (or stuck) in existing models. Something is not working for
you now and you must change. Make your change as painless as possible with
the most potential for growth.
Just my opinion,

Maybe. <grin> ipportfw allows this in a limited way.
The IP Masq tables are normally set up in response to an out-going
connection. The ipportfw patch (built into 2.2 kernels) allows adding
an entry to the Masq tables with a utility. ipfwadm doesn't actually
allow you to open the in-coming connection without the out-going one
to set the tables up.
ipautofw allows you to specify rules to set up in-coming connections
on different ports than the out-going connection was on. This is
mainly used for services that don't have a Masq proxy yet and that use
UDP on a different port number that the out-going UDP packet.
I hope this helps.

Well, when you put it that way, there's nothing wrong with it! :)
Seriously, you *obviously* know what I'm talking about, or else you wouldn't
have pointed out that the two highest-hit DNS records (the MX('s) and A's for
the webserver(s)) are a bad idea for DDNS.
Just take that reasoning that last step further and realize that *any* dynamic
DNS use is not a "good" thing. Simply because some uses aren't _as_ _bad_ as
others, or are so low as to be "below the threshold" for badness or whatnot,
doesn't make DDNS a good idea. If enough people were using it, it would be a
major problem -- so suggesting it's use in usenet is a bad bad thing.
In any event, it's not going to work as effectively as regular DNS with
static IP's, because as I've pointed out before, *many* admins maintain DNS
boxes that *ignore* the TTL field, precisely for this reason. I'd estimate
that at least 10% of all web browsers on the internet use DNS servers that
ignore TTL's (from past headaches involving the renumbering of a very
high-traffic website). One week is the minimum time I'd allow for old DNS
records to be flushed from everyone's caches (no matter what you set your TTL
to). Even then, there will _still_ be some DNS servers that have the old
record (though after a week the percentage becomes vanishingly small).
...and to equate DDNS to SPAM, I suppose it would have been more accurate to
say it this way: DDNS is to DNS as SPAM is to Usenet. That allows the
comparison to be more direct (both DNS and INND provide similar levels of
control and accounting). I *am* assuming high-volume of traffic for
DDNS-supplied name resolution (either one person with a lot of traffic, or
many people with low traffic, it doesn't matter). Given high traffic, DDNS
would result in a considerable portion of the DNS cache space (which is
limited and expensive -- moreso than Usenet storage) being eaten up by
records that change _much_ more frequently than the current average TTL.
That means more forward lookups required, which means higher load on DNS
servers around the world. I'd call *that* an "abuse of the public trust".

Do I need special configuration setup info for Linux??
I recently had a basic DSL line installed using a ALCATEL 1000 adsl
modem. I use a Pentium 200MMX machine running both Linux (Red Hat) and
Windows98.
My network card is a 3C509B.
Everything works great under Windows, but I can't talk to the internet
under Linux.
The 3C509 module is loaded at boot time and appears to be configured
properly. Unfortunatly, Pac Bell DSL is cheap but without Linux
support. USENET reports eth0 is active but neither ping or Netscape
can get through.
Ping works fine for local domain.
As a newbie to linux, you're comments will be appreceated!
