Can Dovecot Use Wildcard TLS Certificates?

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

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?
