Error message in thunderbird that the IP address for my email address was blacklisted

It just happened this morning.  I have consistently received 'Alert from account <account name>.  Temporarily blacklisted IP address..'.  It has never happened before.  I'm logged in from home using Xfinity's WiFi.  Any thoughts?

Depends on the exact error.  This article can help:  https://docs.hetrixtools.com/how-to-remove-your-ip-from-the-comcast-blacklist/  Temporary could be a violation of:

– max 25 simultaneous connections from each individual sending IP address  (email client gone insane and respawning can do it, reboot).
– max 100 recipients for each individual email message
– your IP address reputation may impact these limits

Public IP address change recently?  Someone might have had a bad reputation before you got it.

@XfinityCSAEmail can tell you more.

Hello @user_e16940! I wanted to touch base with you and see if the great tips that @flatlander3 provided helped resolve your concern with the Thunderbird mail client?

@XfinityBillie​ No, but the reply triggered my looking at my account profile and saw that a setting was somehow changed.  I reset the setting and it seems to be working now.  Thanks.
