Although qmail is ridiculously simple - and usually requires a host of plug-ins for expanded uses (like IMAP4 and virtual domains - see my qmail HOWTO translations of Oliver Lehmann's original HOWTO), but the MTA in itself has never had a bug/security hole since I implemented it 2 years ago. If you don't find this amazing, then this post won't make any difference anyway. Come to think of it, I haven't upgraded one of my implementations since 2 years ago... As sendmail issues yet another warning, I sit comfortably, sipping coffee and reading the news. Thank you Dan!
