I'm hosting about 100 domains and we recently built a new box and moved the domains over to it (specs below). Everything in general is working stellar, however, since we moved, our clients are getting random prompts for POP password. Doesn't seem to be any pattern as to who or when. It'll be fine for a week, then one day they'll get several prompts for passwords. 99% have their password saved, and sometimes they can keep clicking to send the same password and it'll go through. Sometimes not - they'll call me, I'll change the password (just reset to what it was originally), and it works. For those that have their clients always on and set to automatically check every X mintues, they will return from being away and find the prompt or a failed message, myself included. I see nothing in the logs that shed a light as to what is going on. My concurrency is 100, with both POP3 and SMTP maxing out at about 25 at the busiest of times.
Any advice or pointing in the right direction is appreciated. Specs: AMD64 Whitebox Gentoo, 2.6.11 qmail - 1.03-r16 cmd5checkpw - 0.30 vpopmail-5.4.6-r1 daemontools-0.76-r4 ucspi-tcp-0.88-r10 relay-ctrl 3.1.1-r2 Thank you. Fred
