Not sure what is going on or even if my assumption is correct.
I have multiple computers that access 5 or 6 accounts with only 1 using imap on a personal server. Lately, and I can't pin down the actual point where all this started, all of a sudden I wont be able to download mail. I can send mail, and looking at the console I see it accepted, but it doesn't go out. It seems like it is batching the mail and not processing the queue until 1.5 hours or as long as 3 hours goes by. then all of a sudden, all the mail shows up.
I have been modifying the filters a lot recently to cut down on spam. I use content control, filtering rules, connection control, and DNSBL servers. But it's not like the mail is getting deleted, it just sits there. Sometimes it kicks off when I use another one of the many devices to access the mail. I think I have 4 computers, 3 phones, 3 ipads, a surface and probably one or two other devices. Mostly I just leave the mail on the server and then ultimately using mail on my imac, pull all the messages on the server and delete them.
Anyway, I am pulling my hair out. I've been using mercury for 15 or so years and it's been pretty reliable. At one point I thought it was the log file size so I deleted the log, restarted, and all the mail came thru. Then I thought one particular computer was getting stuck. Needless to say, nothing is repeatable.
Any Ideas?
Thanks
