We have our company website hosted on a Linux machine. It is sending mail via postfix. The emails are working and being sent to all email clients like Gmail. However, we are not receiving the emails on our exchange server.
When we look at the logs, we see that the connection is being refused, presumably by the exchange server.
postfix/qmgr[11865]: DA6D42FF13: from=<[email protected]>, size=3166, nrcpt=1 (queue active)
postfix/smtp[12474]: connect to mail.sanitizeddomain.com[XXX.XXX.XXX.XXX]:25: Connection refused
postfix/smtp[12474]: DA6D42FF13: to=<[email protected]>, relay=none, delay=172915, delays=172914/0.03/0.07/0, dsn=4.4.1, status=deferred (connect to mail.sanitizeddomain.com[XXX.XXX.XXX.XXX]:25: Connection refused)
We do run Barracuda.
We cannot telnet from the linux machine to our mail server b/c we get the same message.
