Just no go out. Hm. From what I see it's more than just sendmail. Have y ou tried telnet, ftp, etc. to other servers in an interactive session? > God.

I'm getting paranoid about that rickety old Cisco. I'm trying it right now and I'm not getting anything past a connection. I'm running a traceroute from here and I'm not getting anything except * * *'s past 192.197.158.242 (one hop off `main-ethernet0.backbone2.toronto.uunet.ca'). > In conclusion, can anybody run off any kind of list that could cause > sendmail to time out all the time ?
