Looking at your old mails, you seem to be using passdb static for director, but
userdb sql? So you could switch to:
passdb {
driver = sql
args = /etc/dovecot/dovecot-sql.conf
}
password_query = select 'y' as proxy, 'y' as nopassword, if('%a'=143, 1430,
9930) as port
where you'd change the if() to something that handles %s=imap vs %s=pop3 vs
%s=lmtp and %a=143 vs %a=993 vs %a=110 vs %a=995. Maybe a "case" statement
would be less ugly. Or simply make it a real table in sql. Anyway, that's the
basic idea.
