comcast servers blocked by mailspike

comcast servers blocked by mailspike

My email is being refused by an organization that I've been working with for years due to blacklisting of Comcast servers by mailspike.net.  Here are bounce messages involving three different comcast servers from April 14, April 20 and April 21, 2016.

 

Diagnostic-Code: smtp; 550 sender ignored:69.252.207.36/resqmta-ch2-04v.sys.comcast.net was found in the MAILSPIKE.12 blacklist (see http://www.mailspike.net)

 

Diagnostic-Code: smtp; 550 sender ignored:96.114.154.163/resqmta-po-04v.sys.comcast.net was found in the MAILSPIKE.12 blacklist (see http://www.mailspike.net)

 

Diagnostic-Code: smtp; 550 sender ignored:69.252.207.44/resqmta-ch2-12v.sys.comcast.net was found in the MAILSPIKE.11 blacklist (see http://www.mailspike.net)

 

I've gone to to the mailspike IP lookup and requested the IP addresses be deleted, but there are many comcast servers.

 

Apparently, this blocking has been a problem before.  See:

Hope Comcast can reach out to Mailspike again!

Re: comcast servers blocked by mailspike

I solved the problem by switching my outgoing mail server to one provided by http://www.smtp2go.com.  It's free for less than 1000 outgoing messages per month. So far, all is well.
