Comcast Mail Relays Blacklisted

Since 4/16/2018, comcast smtp relays are being added to blacklists.  So far, I've seen the following IPs blacklisted:

69.252.207.39
69.252.207.38
69.252.207.41
69.252.207.35
69.252.207.43
69.252.207.42

You can see the relevant blacklists using mxtoolbox:

This, of course, means that it is impossible to send email to recipients that use these blocklists (e.g. sourceforge).  Please fix.  Thanks.
