Hello,

We've got a qmail/courier (pop AND imap)/clamav/spamassassin setup that's been in-place for over a year, and has been having problems with a delay (varies in duration. sometimes 30 seconds or more, sometimes a couple minutes) when trying to read imap folders, or move messages around (best example is moving a message to the sent messages folder after it's gone through smtp). I telnetted into the imap port, and the delay's holding up the greeting from the server (if I oleh localhost).

I've searched archives and seen that most commonly this is a problem with a dns lookup or an ident lookup timing out, and checked the configs to see what our TCPDOPTS are, and the dns and ident lookups are both off (I know this isn't the best practice, but it was configured like this when I got here (monday heh). Once I've got this solved, I'll put at least the dnslookups back on, but that's later).
