I need a solution
Running a private mail server.
Every mail that I want to sent to a domain that uses messagelabs, the mail bounces.
Maillog shows the following error:
postfix/smtp[1767]: connect to cluster8.us.messagelabs.com[216.82.249.147]:25: Connection timed out
Sending an email from e.g. gmail to an account of that domain works fine.
Anything to look at?
