Just noticed that our mail servers are unable to connect to labs.sophos.com to send spam feedback (is-spam@labs.sophos.com) and it's not just me.

All connections to Mailservers port 25 have failed. The standard port for SMTP transactions is 25, so your servers should be operating on that port. It is recommended that it be fixed in order for your mail service to operate properly. The Mail Servers that failed are:
193.128.114.115 | failed message send with: failed cx open with: failed socket connect with: Operation now in progress
193.128.114.120 | failed message send with: messaging failure: Time out occurred or Remote server closed connection prematurely
193.128.114.121 | failed message send with: failed cx open with: failed socket connect with: Operation now in progress
The other interesting thing is the SOA record.
Primary nameserver: ns-1276.awsdns-31.org.

A serial number of 1 indicates that this is just newly hosted which should not be the case.
