Hello,

After upgrading from CGP 5.1 to 5.2.0, our routing records behave differently (and not because of relay/norelay).

The record in question is:

  norelay:sbcglobal.net = sbcglobal.net@127.0.0.1.2500.smtp

(We have a problem with CGP and SBCGLOBAL, so we offload outbound messages to SBCGLOBAL to a local postfix daemon listening on Port 2500.)

The output of the Test (Mail) button in the Router page is:

  Routed to SMTP host 127.0.0.1:2500(xxxyyy@sbcglobal.net)

But actual messages fail to be delivered as per:

  Failed to deliver to 'xxxyyy@sbcglobal.net'
  SMTP module(domain @70.96.128.85:127.0.0.1:2500) reports:
  host name is unknown

It appears that CGP is trying to resolve the string 2500 instead of interpreting it as a port:
