Your /etc/mail/smtpd.conf may be useful. However, here is an excert from
table(5) that I think applies.
In a listener context, the credentials are a mapping of username and
encrypted passwords:
user1 $2a$06$hIJ4QfMcp.90nJwKqGbKM.MybArjHOTpEtoTV.DgLYAiThuoYmTSe
user2 $2a$06$bwSmUOBGcZGamIfRuXGTvuTo3VLbPG9k5yeKNMBtULBhksV5KdGsK
But, I'm not sure if you are talking about in a listen context or not. I'm
currently sharing my users table in a passwd file with dovecot with no problems.
I do have a seperate creds table in the above format for my listen context.
/etc/mail/users passwd file
-rw-r--r-- 1 root wheel 214 Aug 3 2015 users
relevant doveconf -n
passdb {
args = scheme=BLF-CRYPT username_format=%n /etc/mail/users
driver = passwd-file
}
userdb {
args = username_format=%n /etc/mail/users
default_fields = quota_rule=*:storage=1G
driver = passwd-file
}
I hope this helps.
