Emails going to servers using mxlogic returning "connection refused"

Jump to solution

Hello,

My company has recently (Sat) changed the IP address of our email server. Today, we have received 'connection refused' responses like the ones below from domains that use MX Logic spam-filtering:

Mar 23 20:45:58 swmail postfix/qmgr[3825]: 6F6B9AC0009: from=<csbryson@swalter.com>, size=31588, nrcpt=4 (queue active)

Mar 23 20:45:58 swmail postfix/smtp[4159]: 6F6B9AC0009: to=<hschmidt@acmebox.com>, relay=none, delay=39986, delays=39986/0.09/0.27/0, dsn=4.4.1, status=deferred (connect to acmebox.com.inbound10.mxlogic.net[208.65.145.3]: Connection refused)

Mar 23 20:45:58 swmail postfix/smtp[4159]: 6F6B9AC0009: to=<srosenberg@acmebox.com>, relay=none, delay=39986, delays=39986/0.09/0.27/0, dsn=4.4.1, status=deferred (connect to acmebox.com.inbound10.mxlogic.net[208.65.145.3]: Connection refused)

Mar 23 16:52:38 swmail postfix/qmgr[3825]: A369CAC0063: from=<cmaglira@swalter.com>, size=15739, nrcpt=3 (queue active)

Mar 23 16:52:38 swmail postfix/smtp[14143]: A369CAC0063: to=<invoices@bunzlusa.com>, relay=none, delay=19706, delays=19706/0.07/0.27/0, dsn=4.4.1, status=deferred (connect to bunzlusa.com.inbound10.mxlogic.net[208.65.145.2]: Connection refused)

Thank You.

Hello dpreston,

It sounds like your new IP address is likely on a perimeter block.  If you have not done so already, you will need to contact your support team to open a request to review the IP and remove the block.
