RE: SBC's SMTP server quit working with SMTP connector

I think you misunderstood the problem. Nothing is wrong with the
configuration of the SBS 2003 servers, and my concern does not pertain to the
SMTP connector and default SMTP virtual server. The problem is that I am no
longer able to send emails via SBC's SMTP server. However, I switched the
SMTP connector to use my SMTP server to make sure everything is functioning
okay, and the servers are both able to send mail now. However, I'd like to
get them back on to SBC's SMTP. Is anyone aware of any changes to SBC's SMTP
servers?
