It is not in ports, at least in ports supplied with 3.4 Release, but it is not difficult to do. (I think, someone already added it to recent ports). It works reasonable good for me, but you need virus scan software also. I see at least 8 variant of "PC antiviruses for Unix", but all of them seems commercial. P.S. You need a HUGE swap space, if you users like to send really big e-mails with archived source trees. One of my users sends a 15Mb archive of source tree, and it was swapping around a 45 minutes on Pentium 133 with 32 RAM + 64 swap. (most of all, because it was a squid + imap + apache + dialup here at once.) > > Robert Myers > Systems Administrator > http://whiterose.net > (717)439-1478 > > To Unsubscribe: send mail to majordomo@FreeBSD.org > with "unsubscribe freebsd-questions" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
