got it working with few tweaks .... i had to return '127.0.0.1' as
host for local users ... without that, login process was segfaulting.
And had to return %w as password for the proxied-domains query.
query is: (with linebreaks for easy understanding)
endereco as user,
'/var/spool/mail/%u' as userdb_home,
'maildir:/var/spool/mail/%u' as userdb_mail,
8 as userdb_uid,
12 as userdb_gid,
concat('*:storage=', quota) as userdb_quota_rule,
'Trash:storage=100M' as userdb_quota_rule2,
'Y' as proxy_maybe,
'127.0.0.1' as host
endereco = '%u' and ativa = '1'
NULL as user,
'%w' as password,
NULL as userdb_home,
NULL as userdb_mail,
NULL as userdb_uid,
NULL as userdb_gid,
NULL as userdb_quota_rule,
NULL as userdb_quota_rule2,
'Y' as proxy_maybe,
imapproxy.host as host
imapproxy.dominio = '%d'
that worked flawlessly :) And i didnt had to use JOINs hehehehe
log from the main server, for a proxied user:
Mar 13 23:48:48 correio dovecot: imap-login:
proxy(some at proxieddomain.com.br): started proxying to 10.252.25.2:143:
user=<some at proxieddomain.com.br>, method=PLAIN, rip=127.0.0.1,
log from the 10.252.25.2 server:
Mar 13 23:48:31 correio dovecot: imap-login: Login:
user=<some at proxieddomain.com.br>, method=PLAIN, rip=192.168.1.2,
the only minor problem is that when local users get logged in on
the main server, logs shows that they were proxied to 127.0.0.1 ....
Mar 13 23:33:52 correio dovecot: pop3-login: Login:
user=<localuser at localdomain.com.br>, method=PLAIN, rip=127.0.0.1,
Mar 13 23:33:52 correio dovecot: pop3-login:
proxy(localuser at localdomain.com.br): started proxying to 127.0.0.1:110:
user=<localuser at localdomain.com.br>, method=PLAIN, rip=10.255.176.67,
i can easily live with that .... but i would like to see local
users logged as local connections not proxied to 127.0.0.1.
