More information on dict proxy
by Steve 09 Nov '23

09 Nov '23

Hello, I'm working on an implementation of a dict server. I've looked through all your documentation but can't seem to find how I can create the proper URI to direct the quota plugin to use a TCP socket instead of a UNIX socket. I'd appreciate any insight you can provide. Steve

mail boxes on net mounted filesystem with multiple Dovecots
by lejeczek 07 Nov '23

07 Nov '23

Hi guys. I see that with mailboxes stored on a network mount-point and more than one box with Dovecot using such a mailbox, Dovecots step on each others toes. ... lmtp(minemail(a)lemko.xyz)<2674357><uATxGqbaSGW1zigAn4O9eQ>: Error: lmtp-server: conn unix:pid=2600068,uid=89 [2]: rcpt minemail(a)my.private: Mailbox INBOX: Corrupted transaction log file /VMAIL/my.private/minemail/dovecot.index.log seq 4: ext intro: name_size too large (sync_offset=6368) ... Above happened if the same one user was having mail delivered on two Postfix+Dovecot servers at the same time. I hope experts who know Dovecot's internals better can tell... having such multiple node/server Dovecots "talking" to that same network mount-point but!.. only one Dovecot being active - having Postfix using it and other, however many, Dovecots only "idling" - not having Postifx using it (+ no client connections is a goal too) Would that make such multi-Dovecot setup safe & free from errors as above & any storage related ones? Or perhaps there are other ways to have many Dovecots with the same user-base, using same networked storage simultaneously? many thanks, L. Hi guys.

Can Dovecot Use Wildcard TLS Certificates?
by duluxoz 07 Nov '23

07 Nov '23

Hi All, Quick Q: Can dovecot use wildcard TLS Certificates? I'm having issues with a new dovecot/postfix stack set-up and I can't get mutt on the local box to connect via imap - its coming back with an SSL error, and as I'm using a wildcard cert for the domain I was wondering if that was my issue. If dovecot can use wildcard certs then I'll look elsewhere in my troubleshooting. Thanks in advance Cheers Dulux-Oz

Minimum configuration for Dovecot SASL only?
by Nick Lockheart 06 Nov '23

06 Nov '23

I have a Dovecot IMAP server and a Postfix server on separate machines. The user information is stored in a MariaDB database that is replicated on both servers. Postfix needs to authenticate outgoing mail against our valid user database. I believe this requires us to install a "dummy" Dovecot on the Postfix server so that Dovecot SASL can provide authentication to Postfix from the database. I think Cyrus had a standalone Cyrus-SASL package, but Dovecot doesn't? If I wanted to setup a Dovecot instance on the Postfix server just for the purposes of SMTP authentication, and not use it to handle any mail, what is the minimum configuration required to make that work? Is the dovecot-common package (Debian) enough? Or do I need the full dovecot-imap package? What protocols go in the protocols directive? Can you just make it "protocols = auth" to disable IMAP connections?

install/compile dovecot-pigeonhole
by joe a 03 Nov '23

03 Nov '23

Working dovecot 2.3, wish to be able to implement "server side" filtering. My understanding is that is done with "sieve". My further understanding is that "dovecot-pigeonhole" and be used to manage "sieve" in some fashion. Attempting to compile dovecot-2.3-pigeonhole-0.5.21 proves problematic due to its inability to find dovecot-config. Which is not astonishing as, on my system dovecot-config does not exist, dovecot having been installed as a vendor configure package. Sadly, no vendor package or binary is provided for dovecot-pigeonhole. At least that I am aware of. OS is opensuse LEAP 15.5. Any helpful commentary is welcome. Honest.

Sieve/Pigeonhole

For dovecot, I see there is a "sieve" download at dovecot downloads and separately there is a pigeonhole download. Are these parallel projects, distinct and separate?

Setting up a new server
by James Cloos 30 Oct '23

30 Oct '23

I'm in the process of switching to dovecot for my lan imap and have a couple of questions. I want to keep the folder names unchanged. For mailing lists I use the posting address (eg foo(a)bar.co) for others I use / as the separator. If I use mdbox, will those choices cause any issues? My impression is not, but I'd like to be sure. Also I'd like to use imap-specific passwds for each user. My tests so far have used the login passwds for each user. Not necessarily virtual users, just imap-specific passwds. There is already a pgsql server handy; I take it that would be the way to go for passdb and userdb lookups, yes? Thanks, -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6
