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.

@flatlander3​ Thanks for your quick response.  I got the error message through Thunderbird, but when I logged on to my email account through Xfinity, there was no problem in accessing my email--no error messages.

@user_e16940​ When you go in through the web interface, you're on their server, not your IP address.  They don't block themselves, but they probably still enforce max number of emails, and max recipients.  Also attachment size.  If you tried to send something huge and it's stuck in your outbox, you might hit that 25 connection limit quickly -- just something to check.

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.
