postfix pcre support (for pcre based message rejection)
I need pcre map support so I can reject possible trojan/worm/virus messages. I'm intending to use "Postix Anti-Virus/-Worm/-Trojan Header & Body Checks" from http://jimsun.linxnet.com/postfix_contrib.html. One problem, postconf -m does not show it has support for pcre maps. How can I get pcre to work with postfix? I have postfix-pcre installed.

In my super sophisticated tests, there was no difference (and surprising similarity on each test) comparing cat5 in time to transfer something like a 1gb through a 100Mb switch. I've been told longer runs would bring out the problems of interference either from the signal in the wire or external sources like fluorescent lights etc. Determining one from the other, my cat3 is about 75% the diameter of my cat5. can also see the twists and braids through the insulation of the cat5 which I understand limits radio interference. I would guess the cat5 is of higher gauge too. so use cat3 for ethernet? can't advise it but if you have some on hand it may suffice; don't stretch, fold or otherwise push it, also concider the cost of data loss, downtime and rewiring, should you find the need to rewire. // George -- GEORGE GEORGALIS, System Admin/Architectcell: 646-331-2027< Security Services, Web, Mail,mailto:[EMAIL PROTECTED] Multimedia, DB, DNS and Metrics. http://www.galis.org/george -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
