All my mail, as far as I know, is hosted on murdock. Some of my boxes are mail-only and some are related to shell accounts. Sometime late Friday early Saturday the mail server "forgot" my passwords as it tends to do fairly often. In Apple Mail and Thunderbird, I was being asked for my password over and over. After a while, all the passwords "took" except for m6992695 which took until after Saturday morning sometime to recover.
The "forgetting" of passwords on one or more mailboxes, sometimes just once and sometimes for long periods, is an almost weekly occurance which usually appears to resolve spontaneously, sometimes after periods longer than a "hiccup" of a minute or so. Of course every time there's a "hiccup" I have to type all my passwords back in by hand.
Other issues which I experience commonly but weren't happening within the past 2 days to my knowledge are errors sending via SMTP -- server drops connection or seems to die when a message is sending, or sending messages with attachments is glacially slow compared to how fast it should be over my broadband. Less common but definitely not unheard of are slow attachment downloads via IMAP and slow downloads of headers via IMAP.
I use the old-messages copier to keep my inboxes fairly trimmed.
Thanks for the attention in the forums. I've had 2 tickets open now, one for 27 hours and one for almost 22, regarding the acute issues. They're 1545726 and 1545542.
As for the server move, I have a couple off-site daily backup scripts which I didn't have time to update when I was first offered the move, and I tend to be paranoid about such things even when told it's simple, etc. I currently have all my sites on digdug, and if moving some power users off of it helps things out I'll be content to stay there. I was also told I'd have a couple hours of downtime with a move which I wanted to avoid, or if it was needed, schedule during the wee hours of Eastern time if that's possible.
