Is the log from "doveadm user" enough? It's like below.

Oct  6 16:11:03 box5 dovecot: auth: Debug: master in:
USER#0111#011wellington.epaminondas=sbu.org.br#011service=doveadm

Oct  6 16:11:03 box5 dovecot: auth: Debug:
prefetch(wellington.epaminondas=sbu.org.br): passdb didn't return userdb
entries, trying the next userdb

Oct  6 16:11:03 box5 dovecot: auth: Debug:
sql(wellington.epaminondas=sbu.org.br): SELECT pass AS password,
mail_location AS mail, concat('*:bytes=', quota, 'M') AS quota_rule FROM
mail_users WHERE  user = 'wellington.epaminondas=sbu.org.br' AND
server_id = 1

Oct  6 16:11:03 box5 dovecot: auth: Debug: master out:
USER#0111#011wellington.epaminondas=sbu.org.br#011password=$1$gT9MJF7o
$mactR0nGXtu8X6G.3mJuF0#011mail=mdbox:/var/spool/imap/partition7/b7/wellington.epaminondas=sbu.org.br:INDEX=/var/lib/imap/user/b7/wellington.epaminondas=sbu.org#011quota_rule=*:bytes=1024M

Truncation appears in the "master out" string.

Thanks,
Andre
