Postfix , Dovecot & the Spam fight
Hi,
I'm currently busy with a substiution of my current mail server. I'm
currently using
* Clam-SMTP and
* SpamAssassin
to fight Spam. I wonder if it is worth implementing AmaViS with
SpamAssassin backend instead and also using AmaViS to speak to clamd
directly. But I more and more wonder wether AmaViS is even worth it?! It
currently looks to me as if AmaViS is eating LOTS of

Postfix setup
I'm trying to clarify the various ways in which I could set up
Postfix + Dovecot + SpamAssassin under CentOS-7,
and I'd welcome any comments on the following remarks.
As far as I can see there are 3 standard ways of setting this up:
1. Use amavisd
2. Use dovecot + pigeonhole/sieve
3. Use spamass-milter
At present I'm following (2), but am thinking of going over to (1),

sendmail and spamassassin
I have a problem getting spamd and sendmail (both stock CentOS4 rpms)
to work together on a couple of smtp relay machines. This is clearly
a configuration issue and no doubt revolves around my lack of
comprehension of how this is to work.
Basically, the setup consists of two frontend public smtp transports
that redirect all email through a firewall to an internal imap server
for final

Disabling Spamassassin on outbound email
Does anybody have a good method for disabling SA checks on outbound
email under sendmail running the spamass milter? Some of our Vhost
accounts are getting flagged as spam on the way out due to being on a
dirty ISP network.

Spamassassin as root and pyzor
I've just set up a new mailserver using Centos5.2
(sendmail+clamav-milter+spamass-milter).
I'm using the spamass-milter package from rpmforge
(spamass-milter-0.3.1-1.el5.rf).
I notice that the default setup is to run it as root. I set up my
previous mailserver on Centos4, and I can't remember if I did anything
special, but on that machine it runs as user "sa-milt".

Rejecting spam
Sorry, not a direct CentOS question, but I know there's a lot of
experienced users on this list...I'm using CentOS with sendmail and
spamassassin. I've got it configured with spamass-milter and it is
working correctly. However, I was expecting to be able to reject mail
that is marked as spam, not just deliver it as usual. Anyone know if it
can be done and how? I know a milter

Moving Spam to Junk Folder
I am following this tutorial:
https://www.linuxbabe.com/redhat/spamassassin-centos-rhel-block-email-spam.
I followed the steps in "Move Spam into the Junk Folder". When I send an
email from a blacklisted e-mail address, I get a bounce e-mail from my
e-mail server. Here is what is in my spamass-milter file:

Use postfix and spamd on CentOS 6 - looking for a shortest guide
Hello fellow CentOS-users,
on the net there are lots of Spamassassin related HOWTOs - describing how
to create a shell script for Postfix and how to install Spamassassin and
start its spamd daemon - step by step. Additionally antivirus setups are
described...
But I have a strong feeling, that this is unneeded on CentOS 6 - because
there are already preconfigured stock packages for postfix and

Up to date guide/information Sendmail SMTP Auth
Hello all,
I've been googling my brains out since yesterday looking for up-to-date
information on this matter, and have found information that is anywhere
from 15 to 5 years old. I'd really like some information that much more
up to date on the subject. Specifically configuring Sendmail SMTP
authentication (_no smart host stuff_).
I've got Sendmail 8.14 installed on a CentOS 7.3

dovecot + pigeonhole on CentOS-7
I've everything running fine under CentOS-7, as far as I can tell,
except that spam is not being diverted to my spam folder

I'm running postfix + spamass-milter + spamass-milter-postfix + dovecot
(+ spamassassin), and spam is being duly marked
before ending in my inbox .
As far as I can see, the current advice is to leave filtering

mail server best practices question
Hello all,
About a year ago I set up a mail server on CentOS using this howto:
http://wanderingbarque.com/howtos/mailserver/mailserver.html
I managed to add amavisd-new with clamav and spamassassin.
It runs very well, but it runs on CentOS 5.2, and if I try to upgrade,
amavisd-new and clamav break.
we are now also at the point where a backup mx will need to be implemented.

/var/amavis
Hello all,
My /etc/group is not quite in order (a long story), and now I need to
correct privileges right here and there.
I would ask someone who has amavisd-new to show me the corresponding
listing as this:
[root at mail amavis]# ls -l /var/amavis
total 20
