We have upgraded to a T1 line. The T1 line provider (CTC Communications) provides our Internet connectivity, but we are continuing to use the same company we have in the past for our email (SoVerNet). In order to send email to SoVerNet over the T1 line, they require authentication and a different mail server from incoming mail. The outgoing email SMTP server is smtpauth.sover.net, whereas the incoming POP3 is mail.sover.net.
The POP3 Connector Manager in Exchange 2003 and the Internet and Email configuration wizard in Windows 2003 SBS Server do not provide separate outgoing (SMTP) and incoming (POP3) options.
The only way I have gotten our email to work is to set up a POP3 account on each individual XP machine, because that interface does differentiate. However, this is not a longterm solution because users must choose their intranet or internet account prior to sending email and we cannot email both within Exchange and outside at the same time.
Is there a workaround that would enable me to have all our email routed through Exchange?
