SMPT Socket Error 10060

Post by katopodisp » Sat Oct 19, 2019 2:26 am

Hi everybody,
I would like to make a question about a usual, judging from the Google results, issue with MailEnable SMTP.
I have a Windows Server 2012 machine with everything set up and working finely, but although I have tried everything to correctly configure MailEnable SMPT (Firewall Rules etc) I am still getting "socket connectivity errors".

To be more specific I am pasting the error log here:

Fork/Split: Message ID [7BA2F0A04BB64718B80995C437B87389.MAI] requeued/split into 1 messages for delivery to target domains.

Hi,

Open up a Windows command prompt with elevated privileges on the MailEnable server and try to telnet to alt3.gmail-smtp-in.l.google.com on port 25. If you cant connect then you have a problem with port 25 outbound. Maybe your ISP is blocking port 25 outbound.
