I had setup postfix and spam assassin, and in my environment, I forward the incoming email to my exchange server.
Everything works now, in my mail box, I can receive the email with subject ******SPAM*****. but is there a solution, when spam assassin finished the scan and mark spam, if the score is very high, may be stop to forward it to exchange, for example, send it to a special email box?
I've got a web server that's hosting a few sites, and there are a few WordPress instances with these sites. With Wordpress, whenever a user registers with the site, they receive an email.With my server, it sends mail via Sendmail. This is all fine and good, except no matter what, it's flagged as spam. Is there any way to correct this?Keep in mind that this isn't a mail server, and the only reason the server ever sends mail is for new wordpress users and password resets.

Something light, as it needs to be installed to a guruplug server with not much storage available. It would be great if I don't need to configure a fully fledged mail server but if it can function on it's own, only filtering spam messages. I already found assp and qpsmtp, but I find these very difficult to setup and assp is like huge.

I need help with header_check filter on postfix. In the last week mail users received a spam e-mail without subject line and I don't know what is the way to reject this. This is the example of message header:
From: "example@example.com"
Date: September 16, 2010 9:07:43 AM GMT-04:00
To: <example@example.com>
I want to reject e-mails that don't have Subject line
Very new to Ubuntu and Linux so this may be a simple one. I've recently setup an Ubuntu Server 10.04 box as a mail relay running Postfix and Amavisd-new (Spamassassin & ClamAV) and this has been working really well. I started to get a few emails through today with the following header[URL]..(removed domain name) The name's always in quotes and random. The fqdn is that which I configured in postfix as $myhostname. I can't figure out how this address is being used. This box is only used for incoming mail and acts as a relay to Exchange. Exchange doesn't send out through it. The only thing that may be going outwards is bounced messages from Exchange which are almost exclusively to linkedin.
The fqdn isn't public. This box isn't even part of our internal domain, it's just named that way with manual DNS added. Anyone seen this before? Will this header have been part of the message when it arrives at postfix or could this have been added by postfix itself?
I am using postfix as spam Mailscanner to protect my mail server running sendmail. The problem is that when I forward an email from MailScanner mail me back with the following error:
<postmaster@localhost.@mydomain.com.>... Real domain name required for sender address (in reply to MAIL FROM command))

I am using CentOS 5.3. I was half way through that and got an email that had ***SPAM*** in the subject. Haven't received any more. First of all I want to know if spam will still get delivered, and just have a modified subject. Second, I want to know how to set it up so Spam goes to a user's spam mailbox (Virtual Users). And third of all, is it possible to disable spam filtering on a user basis, preferably using MySQL tables? Is it possible for users to mark a message as spam, and all further messages sent from that address will be sent to spam folder but only for that user?
EDIT: Yes spam is getting delivered with a modified header, on the server site, how can i deliver to spam folder? how to create IMAP virtual mailboxes on request without having to send an email to them first? Using virtual users with Courier Imap
I have a system running at home that uses Getmail to retrieve mail from my ISP's pop server. Dovecot then offers that mail over IMAPs to my desktops running Thunderbird.
The reason I have resorted to using Getmail is because I don't have a static IP (from my ISP) for my server, and thus this server doesn't act as an MX.
I have implemented Spamassassin in my Getmail script as described here.
From further research, I understand that in order to fully utilize Spamassassin 's potential, I have to resort to training it with SA learn.
Currently I still receive spam messages, but 50% of spam is marked as ****SPAM****, and the other half is not marked at all.
My question is this:
1) How do I get getmail to move messages marked as spam by spamassasin to be moved to a JUNK folder within my mailbox automatically?
2) I thought of creating a folder where my users can move messages they deem to be spam, and set up a crontab script to invoke salearn regularly on this folder to get the bayes engine to learn from it. Is this the correct way of doing it?

i get about 30 of those a day, everyday, for a long time. ive asked the ISP to stop it (theplanet.com) they are not responding and the spam continues. i was thinking is there a way that i can tell postfix to reject emails that contain "No Cost Website Analysis and Ranking Report" in their subject? there must be a way but i dont know how.

Our primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.
A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.
A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:
ISP supplied CISCO router
Draytek VigorPro 5510 UTM
Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:
CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server
I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...
I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far.

The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:
