Our outbound smarthost smtp server is carefully monitor, has never lost a single mail message, and screaming fast at getting email out. After all we also run commercial opt-in bulk emailing for large clients and we do know how to get 100's of thosands of messages out in a real fast way. Probably mork work has been put into our smarthost than any company has bothered to put into thier smtp relay. Your work also has a serious security concern if it allows this you to directly attatch to it's port 25. Can you say firewall circumvention... I thought so. -- Rod Grimes - KD7CAX - (RWG25) rgrimes@gndrsh.dnsmgr.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
