Hi Timo and All, how does Dovecot act when an MTA tries to deliver a multiple recipient message to a LMTP proxied system? Does it uses server affinity table for each recipient? I use lmtp_destination_recipient_limit = 1 setting in postfix to avoid multiple recipient delivery. Is it right? I use lmtp_destination_concurrency_limit = 1 too, but i think that it's useless or, maybe, it can make performance worst. Luca

...ecipient within single session. It seems, that Dovecot LMTP restores root privileges not between each recipient delivery attempt but after whole transaction. The only solution is throttle Postfix to send single message with multiple recipients as many small transactions - all with only ONE rcpt. lmtp_destination_recipient_limit=1 makes this magic. Otherwise you can find: Dec 12 03:30:36 vm dovecot: lmtp(3580, info at xxx.com): Fatal: setgid(48672 from userdb lookup) failed with euid=33001, gid=43570, egid=43570: Operation not permitted (This binary should probably be called with process group set to 4867 2 instead of 43...

...ot via LMTP, it often gets an error "451 4.4.0 Remote server not answering (timeout while waiting for reply to DATA reply)" from the Director. Service LMTP is configured with "client_limit = 1" on Director en backends (others limits are default ones). Postfix is using "lmtp_destination_recipient_limit = 1" and "lmtp_destination_concurrency_limit = 1". I want that incoming messages are stored one after one per recipient (have a queue per recipient). I does not seem to be done actually. I think Postfix is sending too many messages at a time to Director. How do you do to handle...

Hi, I'm not sure if this is a deliberate design decision or a technical limitation that I've missed. Please briefly explain if so :). Or a bug or feature request? When LMTP receives a mail with a single recipient it adds a Delivered-To header. However if the message is delivered in a batch that header isn't added. At first I thought maybe the LMTP was doing something with hardlinks

This is my master.cf line for dovecot virtual users: dovecot unix - n n - - pipe flags=DRhu user=vpopmail:vchkpw argv=/usr/local/libexec/dovecot/dovecot-lda -f ${sender} -d ${user}@${nexthop} -m ${extension} I would like to also write every mail, before delivery to the user, to a backup location like /backup/imap/mm/dd Possible? -- 'On whose authority?'
