Many thanks for helping me solving my problems After a few conf tweakings, dovecot works so well that I may put it on prod tomorrow. Many thanks to Timo!!! A few questions though: I had to raise the number of auth_process to 10 to avoid tons of messages "can't connect to socket 'default' is that ok? After tweaking my postgresql database to authenticate virtual users I notices that SQL userdb MUST have home AND mbox file. Not wanting virtual users to have anything but INBOX, I've set home dir in query to /tmp/%u. is that ok too? Best regards to all and many thanks again. -- Olivier PRENANT Tel: +33-5-61-50-97-00 (Work) 15, Chemin des Monges +33-5-61-50-97-01 (Fax) 31190 AUTERIVE +33-6-07-63-80-64 (GSM) FRANCE Email: ohp@pyrenet.fr ------------------------------------------------------------------------------ Make your life a dream, make your dream a reality.
