Okay, here's the situation:

I have a SLES 10 SP1 server. Among other things, it does mail. I have a fairly standard Postfix + Cyrus + Amavis + SpamAssassin + ClamAV setup.

I'm trying to get Postfix to let me use PCRE lookup tables for the header_checks filter (in particular, to block various attachments).

The problem is, my Postfix doesn't seem to support PCRE. When I type postconf -m, I get several results, but pcre isn't one of them. Yes, I have regexp, but POSIX regular expressions don't help me in this situation.

All of the PCRE packages are installed. Even the postfix package itself shows it provides dict_pcre.so()(64bit). I'm not quite sure if that means Postfix was compiled with PCRE support, but it sure looks that way to me.

So yes, I have a Novell SUSE Linux Enterprise 10 server, but our support only gives us security updates and bug fixes. We don't get incident support in our support contract, and we can't afford to pay them a wad of money to tell us whether or not Novell's Postfix has PCRE support (we're a small operation).

So what do you think? Where should I go from here?

Hi,

unfortunately, I cannot find the source package from your exactly version.
But checking in the update packages from SLES 10.2, seems to have pcre support.
Check if the file /usr/lib/postfix/dict_pcre.so exists.
Anyway, postconf -m must show pcre extension, I guess.

You could do a quick test creating a rule as below (you don't need to stop the service):

- create the file /etc/postfix/pcre_test:
/^Subject: test/ REJECT

- and execute:

postmap -q "Subject: test" pcre:/etc/postfix/pcre_test

If the word "REJECT" appears, pcre extension is working.

Regards

I did as you suggested and I get this:

postmap: fatal: dict_open: unsupported dictionary type: pcre: Is the postfix-pcre package installed?

But according to YaST, there is no postfix-pcre package to install. I'm confused!!!

It's fixed. My dynamicmaps.cf was empty. I restored the originals and postmapped dynamicmaps.cf and it works.
