I'm new to Dovecot and will be using it with Postfix. I'm looking for recommendations regarding the use of Dovecot's LDA or LMTP for virtual mailbox delivery. Many of the simple examples on the wiki use LDA. So I've set that up initially. But apparently an advantage of LMTP is recipient verification. So, as I understand it, LMTP would let Postfix know whether or not the message was deliverable to a local virtual recipient without needing to have a separate virtual recipients map in Postfix. That sounds like a nice simplification. But I see in Ubuntu that the dovecot-lmtp package is not marked with the Canonical support icon, like the pop, imap, and other packages are. I don't have a contract with Canonical. But I'm wondering why they would not support the lmtp package when they do support most of the others. Is it possible that the dovecot LMTP package is not as stable or reliable? I'd appreciate comments from experienced users of postfix with dovecot. Are you using Dovecot LDA or LMTP and why? Thanks much, Michael
Hi Michael,> I'd appreciate comments from experienced users of postfix with dovecot. > Are > you using Dovecot LDA or LMTP and why?I have LMTP with dovecot running on Ubuntu 14.04 and Ubuntu 16.04. LDA is the worser solution, this is best explained in chapter LTMP in Peers dovecot book, which is unluckily in german and more or less out of print. But you can easily grasp the configuration details and reverse engineer the technical german phrases ...> > > > Thanks much, > > Michael > > > >-- kivitendo mit Schnelleinstieg zu RB-Druckvorlagen im Linux-Magazin 07 DELUG-DVD Ausgabe Richardson & B?ren GmbH Jan B?ren K?lnstr. 311 53117 Bonn USt-IdNr.

The most crucial difference is that LDA is intended for delivering email to a *real* user.

Thanks Jan. I've been trying to obtain an English copy of the Dovecot book for months, prior to starting this project. So far, I just can't find a copy. It's too bad that the author/publisher won't do a second printing or, if they're not interested in making any more money, then release it to the public domain as a PDF. Very frustrating.
