Hi,

We are planning on migrating to procmail? What do we need to do to convert our sendmail config?

They're not designed to do the same thing : procmail is a mail delivery agent (mda) and sendmail is a mail transfert agent (mta)
By default sendmail uses procmail to deliver mail locally ! so maybe you have to explain us (better) what you're trying to do ...

Hello, I have also installed postfix, mailscanner, postgrey and clamav in centos as antispam-antivirus gateway. It works great for me. Also installed vispan & mailscanner mailwatch to monitor the server. I have write a document and like to share with you people. You can get the doc here.

Well What the Heck, I'll post mine too!

Mine is Scalix email server (http://scalix.com)
Very nice user interface, talks to Outlook for calendars and scheduling and all that nonsense.
Basically an Exchange drop in.

So, if you wanna see my HOWTO, CentOS4.4, Scalix, spamassassin and clamav,
it's here:

Hi All.

I cant seem to be able to update clamav via yum? The kbs-CentOS doesn't seem to be up to date. How do I update clamav to latest version?

Doug - the above link goes to a black hole but I'd appreciate seeing the notes as I am about to embark on a Scalix trial.

Thanks

Good luck! Check out the forums on the scalix site, lot of good info.
Scalix just got bought by Xandros, not sure if that's good or bad...

The [url=http://wiki.centos.org/Repositories]Repositories[/url] page on the [url=http://wiki.centos.org/]CentOS Wiki[/url] indicates that the [url=http://wiki.centos.org/PackageManagement/Yum/Priorities]Priorities[/url] plugin for Yum should be installed before using 3rd party repositories, such as the ones mentioned above.

This did not work at all for me, se linux balked on almost everything. I did achieve the same thing via a slighlty different path
[url=http://forums.fedoraforum.org/showthread.php?t=196234]sendmail Mailscanner clamav howto[/url]

works great on Centos 5.3 I am also using APF, BFD, LES, PRM, LSM, chrootkit, rkhunter for more seccurity also here is a trick if you are using your server as an outgoing relay only add the following to the end of your /etc/mail/access

1 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
2 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
3 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
4 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
5 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
6 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
7 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
8 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."
9 ERROR:"551 We do not accept mail sent directly to our servers. You must use the valid MX record of the domain that you are sending to."


this will cause everything that you have not specifically configured to recieve from not be able to use your mail server.

rember to makemap hash access < access and restart your sendmail
