We host a mail server which runs Postfix and there has been a few times where
one of our clients computers becomes infected with malware and the password is
compromised.
How this has come to my attention is because every once in a while, I will
login to the mail server and see an unusually
I'm trying to enable postfix to use an SSL certificate for sending email but
when I enable SMTP on my outlook client, I get this message:

Our postfix server acts as a spam server for a number of domains and is
designed to forward email to the final destination; it has not been setup as a
local mail server.
Every once in a while, it will attempt to send an email to
root@NT-SPAM01.adetor-lan.InternalDomain.local and will be
This seems like it should be a simple task but for some reason Postfix isn't
rejecting email by using RBL lookups.
Here is my smtpd configuration:
smtpd_recipient_restrictions =
reject_non_fqdn_sender,
reject_unknown_recipient_domain,
reject_unauth_pipelining,
reject_non_fqdn_recipient,

I'm currently tasked with a project of creating a spam server which will
receive email for all of our customers, filter it for spam and relay clean mail
onto the final destination. The challenge is that it needs to be manageable by
someone who doesn't know Linux.
Is there a way to add
I'm attempting to setup postfix to direct incoming email to a perl script which
will in effect scan the email with SpamAssassin and scan for viruses however
when I added the configuration to my master.cf file, I'm getting an error.
The mail log reads as so:

Hey All,
I have a user trying to send an email however it was bounced back. After
checking the maillog, I found that it was timing out when sending RCPT TO.
I telnet'ed into the recipients server and started sending the series of
commands to send mail and it seemed very quick up until I sent RCPT

Hello!
I've been trying to figure out the best way to drop/sort spam with
virtual users. All documentation I could find didn't fit to our
virtual configuration and I'm a bit confused what's the
best way to drop spam.
Our setup is postfix+cyrus-imapd+spamassassin.
Hello,
In our environment, we have a postfix server that receives mail and forwards
only the HAM onto Exchange.
I have several users that are using notebooks and looking to send and
receive mail remotely. I have Exchange setup to allow IMAP connections and
forwarded the port on the firewall.

I am running CentOS 5.4 and the latest version of Postfix it has on the
repository is version 2.3.3. After looking at the Postfix site I found out that
that version is no longer updated.
Is it worth downloading the source code for the latest stable version and
manually compile and install it?
Maybe this is not the best practice, however I don't block any incoming mail
(destined for a legit address) for the same reason. I use a program called
SpamAssassin Quarantine and I let it scan for the spam.
Spam is put in quarantine and doesn't effect the users. It sends out an email
