Comcast.net back on UBL spam blacklist

Come on guys, this is getting old.  This is the second time in the last couple of months that Comcast was blacklisted.

 

Here is the error message:

P  L  E  A  S  E resolve this.  I regularly need to send email to the Miami Dade Police Department, and they use UBL to filter spam.

Lashback is an interesting list.

 

We've reached out to the MDPD, hopefully they'll get back to us soon.
