[Dovecot] auth-worker temporary failures causing lmtp 500 rejection

2012-01-26 Thread Mark Zealey
Hi there, I'm using dovecot 2.0.16 with a mysql user database. From time to time when we have a big influx of messages (perhaps more than 30 concurrent rcpt to: sessions at the same time so no auth-workers free?) or when we have a transient issue connecting to the database server, we see the

I've tried reproducing by having long running auth queries in the sql and KILLing them on the server, restarting the mysql service, and setting max auth workers to 1 and running 2 sessions at the same time (with long-running auth queries), but to no effect. There must be something else going on

Hi Sounds very cool. I already have dovecot set up as a proxy, working, and it should allow me to forcefully disconnect users and lock them out while they are being migrated and then once they are done they'll be served locally rather than proxied. My main problem is that most connections

Hi Yeap, taht's what I'm doing to do, except that I would have to proxy more than just IMAP and POP - it's a one-does-it-all kind of machine accepting mail delivered from the outside, relaying outgoing mail, does webmail, does all this things very poorly... I have the choice of forcing all
