no, and there's the problem. if the static-ip connection is down, postfix reports "warning: smtp_connect_addr: bind x.x.x.x: Cannot assign requested address" and then it binds to the dynamic ip and uses that. Why not add an option so that if the binding to the smtp_bind_address fails that postfix refuses to send mail. -- Best regards, Sven mailto:s...@clamav.net ClamAV, a GPL anti-virus toolkit http://www.clamav.net
