Since this morning, our qmail reports the following when we try to send a mail:

The only change since yesterday:
The virus scanner has updated (like every night). We use mcafee and the system is a SuSE Linux.
The responsible person for this mailserver is not rechable.
Has anyone an idee how to fix this? This is very urgent.
The service faded out since yesterday. Yesterday at 6 pm we received the first errors (once every 5 to 10 minutes), then it got worse and since today 10 am we are not able to get or send any mails.
are you sending mails directly or are you relaying through another server ?
if its the former, try manually telnet to the port 25 of the mx server of one of the domains like fedex.net from the qmail server and try sending a mail
in case you need here's the reference for trying to send mail via telnet.
this way it can be isolated to a system level issue ( like dns not reachable, firewall problems etc) or a qmail configuration issue.
