  • 1.  messagelabs.com "Connection timed out" from my mail server

    Posted Jun 20, 2017 07:26 AM

    Hi,

    I'm trying to send an email to a messagelabs.com address but unfortunately it's being rejected. This is from the logs:

    Jun 20 12:00:34 melkor postfix/qmgr[780]: 106FF1D4: from=<XXX>, size=1266, nrcpt=1 (queue active)

Jun 20 12:03:04 melkor postfix/smtp[3072]: connect to cluster3.eu.messagelabs.com[85.158.136.3]:25: Connection timed out                                              
Jun 20 12:03:04 melkor postfix/smtp[3072]: 106FF1D4: to=<XXX>, relay=none, delay=150, delays=0.09/0.01/150/0, dsn=4.4.1, status=deferred (connect to cluster3.eu.messagelabs.com[85.158.136.3]:25: Connection timed out)

    Ths server I am using is a VPS which I know has had spam sent from it in the past (judging by the number of blocklists I had to be removed from), but it should be clean now. Could someone have a look?

    This is my server:
    melkor.jcowgill.uk. 2209 IN A 185.145.46.63
    melkor.jcowgill.uk. 3156 IN AAAA 2a07:4580:b0d:7b9::1

    Thanks,
    James
