Hi I run qmail as mail server SW. When I configured my Watchguard Firewall II to use SMTP proxy a lot of mails stayed in the queue, and I got "connection died" in the maillog. The problem arised when MX-records pointed to a "closed" server. I don't now why, but qmail never tried the other servers according to MX-records? If I delete the SMTP proxy, and only alow traffic on port 25 this works fine..... -- /hans
