> Is anyone having a problem with postfix (Imgate) not delivering >Hotmail and MSN accounts?
it happens from time to time. their MXs get very slow, and postfix "smtp_*_timeouts" timeout when trying to send smtp_connect_timeout = 30s smtp_data_done_timeout = 600s smtp_data_init_timeout = 120s smtp_data_xfer_timeout = 180s smtp_helo_timeout = 300s smtp_mail_timeout = 300s smtp_quit_timeout = 300s smtp_rcpt_timeout = 300s smtp_rset_timeout = 20s either you wait for msn/hotmail to clean up their mess, or you increase your SMTP timeout JUST to handle the msn/hotmail mess. The problem is that increasing your timeouts affects all postfix sending to all MXs, not just msn/hotmail. If you look for other "smtp.*timeout" in your maillog, you will get some feel for the situation. with 9000 backed up, you better increase your SMTP timeout dramatically just to bet the mail delivered.
