Hello Linux GURUS,

I am farely new to Linux systems.. I have some working knowledge of Linux but thats very little.

I have setup Spamassassin for one of my clients. I did it by following the online tutorials available on the Spamassassin site.

Now I want to check :

1. On which port spamassassin is running..

2. and my spamd configuration.

I have to set SpamAssassin to be set up to listen on IP xx.xxx.xx.xxx, and in addition, it should be set up to accept connections from IP yy.yyy.yyy.yyy.

To the best of my knowledge, this is done by adding the following parameters with spamd command:

spamd -i xx.xxx.xx.xxx
spamd -A yy.yyy.yyy.yyy

Now after configuring how can I check my Spamd configuration.

Expecting your early reply.

Thanks

Diptanjan

Is usually listen on tcp 783 port. netstat -ntulpn is your friend to get open port list and program name:

Code:

 netstat -ntulpn

Basically you force sendmail or postfix to send all mail through procmal , so there is no need to set up a ~/.forward file.
If you are using Postfix add following command to /etc/postfix/main.cf

Code:

mailbox_command = /usr/bin/procmail

Restart postfix.

Next in /etc/procmailrc you add something as follows.. which tells to filter everything through spamassassin:

Code:

# Send all mail through Spamassassin
:0 fw
* < 256000
| /usr/bin/spamc -f -u mail

Replace line with /usr/bin/spamc -f -u mail with actual path to spamassassin file.

That is all you need to do to get started with Spamassassin.

Thanks again Tom,

the "netstat -ntulpn" command is really helpful.

Does this command work on all versions of "-NIX" ?

Thank you for your help

It should work on all Linux distributions, however *bsd and other UNIX slightly modify command syntax, in any case by referring man page your should get the idea. On a related note you can use lsof command for same purpose.
