I have three Postfix instances, A, B and C. A is an MX for B and C's
domains and the relayhost for B and C. B and C are mailbox and
submission hosts for their users. The servers presently use PLAIN
authentication. I want them to use DIGEST-MD5 authentication instead.
Software:
Dovecot 1.1.7 (on A for auth, on B and C for auth and IMAP)
Postfix 2.5.5 (all instances)
Cyrus-SASL 2.1.22 (on B and C for SMTP client SASL)
The username format is u...@example.com.
For the DIGEST-MD5 mech, Dovecot expects:
username = user
realm = example.com
however, Postfix sends:
username = "u...@example.com"
realm = ""
I haven't found any settings that affect how Postfix splits the username
retrieved from the smtp_sasl_password_map nor any options to change what
Dovecot expects.
How do I fix this?
