Hi, looks like we detected a serious bug in dovecot's lmtp proxying where e-mails are delivered to the wrong user. The setup is: *) Dovecot is configured with "lmtp_proxy=yes" # Support proxying to other LMTP/SMTP servers by performing passdb lookups. lmtp_proxy = yes *) Postfix uses "dynamic recipient verification", so Postfix starts sending a (verify) mail by LMTP to dovecot, but quits the lmtp-session right after the RCPT TO:. No DATA-stage is re...

...set up postfix to deliver mails to dovecot (2.0.16) using LMTP. On the other hand, I've successfully configured the IMAP proxy setting in dovecot in order to be able to distribute mailboxes among different servers. I wanted to do the same proxy at LMTP level, but it's not working. If I put lmtp_proxy = no, then everything works ok (assuming the mailbox is local), but when I set lmtp_proxy = yes then the user is not found when deliverying the message via LMTP, so the mail remains in the postfix queue. Users are validated through active directory. However, this AD hasn't the SFU installed, t...

I receive a local mail when I do a 'mail test' on a backend svr1 with this[0] configuration. However when I just add only one configuration change 'lmtp_proxy = yes' I am getting these errors[1]. I would expect this email to still be delivered locally, should this be working or do I misunderstand the lmtp proxy functionality?

...entials, and then forwarding to IMAP server running on backend. As a first step, I would like to continue using my files to authenticate uses (so passwd file , and users.DIGEST-MD5), but final goal will be using a MySQL DB. So my main question are : 1) I just made a test and changed "lmtp_proxy" to "yes" in my 20_lmtp.cong file, but, strangely, this did not cah nge anything ! The LMTP process still receives mails and stores them on the local host , 2) Are there any documentation describing this process in details ? I only found some pieces on wiki pages, but not enoug...

...f configured, but expects valid user credentials. The larger use-case is a migration from cyrus to dovecot. As it's not just the MDA but also the MTA installation that is being migrated I need a way to deliver mail from the old MTA to the new MDA. LMTP comes in handy. https://github.com/ixs/lmtp_proxy/blob/master/README.md#minmal-downtime-migration-of-users has a rough invocation of the steps needed for that. As I said, LMTP auth isn't critical for this, but would have been a nice addition. cheers, Andreas

Hi Aki, I also tried with changing the original ldap source to svr2. Although everywhere svr2 is configured, still mails keep being delivered locally on svr1.
