I think you need proxy solution on top of dovecot, e.g create two subdomains allocating one for each server and configure dovecot with each, and use haproxy to forward each subdomain requests to each server mta or mail server(imap, pop3) i.e. dovecot ports.

I host two email servers, example1.com and example2.net. How can I configure Dovecot 2.4 to distinguish between the two?

When I was running Dovecot 2.3, I was able to send and receive email to and from example1.com and example2.net. I want to be able to do the same with 2.4, but right now when I try to start Dovecot I get an error message like this:

This most likely means you forgot to close with } an earlier section. v2.4.0 unfortunately gives a rather bad error message in that case. It'll be better in v2.4.1.

I've searched the dovecot.conf file thoroughly and can't find any unclosed brackets. Should I post the whole thing (with appropriate obfuscation, of course)?

A quick check would be if there is a different count { and }: diff <(grep -E "}" -c -r /etc/dovecot) <(grep -E "}" -c -r /etc/dovecot)

This executes grep -E "}" -c -r /etc/dovecot and grep -E "}" -c -r /etc/dovecot and prints any differences via diff

Okay, here's dovecot.conf in its entirety (with strategic obfuscation, of course).

## Dovecot configuration shipped with debian packages

dovecot_config_version = 2.4.0 dovecot_storage_version = 2.4.0

protocols = imap lmtp sieve lda

!include_try conf.d/*.conf

auth_mechanisms = plain login

sql_driver = mysql

# The mysqld.sock socket may be in different locations in different systems. mysql /var/run/mysqld/mysqld.sock { user = MariaDBuser password = MariaDBpassword dbname = MariaDBdatabase

#ssl = yes #ssl_client_ca_dir = /etc/ssl/certs } # Alternatively you can connect to localhost as well: #mysql localhost { #}

passdb_default_password_scheme = SomethingSecure

passdb sql { query = SELECT user AS username, domain, password FROM mailbox WHERE user = '%{user | username}' AND domain = '%{user | domain}' AND active= '1' } userdb sql { query = SELECT home, uid, gid FROM mailbox WHERE user = '%{user | username}' AND domain = '%{user | domain}' AND active= '1' # For using doveadm -A: iterate_query = SELECT user AS username, domain FROM mailbox }

ssl_server_cert_file = /etc/letsencrypt/live/mailserver.example1.com/fullchain.pem ssl_server_key_file = /etc/letsencrypt/live/mailserver.example1.com/privkey.pem

local 127.0.0.1 { local_name mailserver.example1.com { protocol imap { ssl_server_cert_file = /etc/letsencrypt/live/mailserver.example1.com/fullchain.pem ssl_server_key_file = /etc/letsencrypt/live/mailserver.example1.com/privkey.pem } }

local_name mail.example2.net { protocol imap { ssl_server_cert_file = /etc/letsencrypt/live/mail.example2.net/fullchain.pem ssl_server_key_file = /etc/letsencrypt/live/mail.example2.net/privkey.pem } } }

Timo suggested there might be an unclosed { somewhere before the section with the cert files, but I don't see any. Does anyone see what I've missed?

If } isn't here on its own line, that's one explanation.

Fixed that; thanks for pointing it out!

Also here seems to be missing two } lines.

Apparently I cut off the copy two lines short.  My bad.

Tried starting Dovecot again, this time got an "unknown protocol" error about lda.  Took that out of dovecot.conf and it started fine.

So why can't I log in from Evolytion?  Here's the error message Evo gives me:

Temporary authentication failure. [mailserver.example1.com:2025-02-13 12:37:22]
