For the 3rd time in the past 10 months, I cannot receive or send emails through Thunderbird on my laptop. Again, a pop-up states IP address is temporarily blacklisted and another states cannot login to imap.comcast. This always happens after a Thunderbird automatic update. (Last auto-update was Jan. 22, 2025. Haven't been able to access Thunderbird email since then. Have checked settings and all are set as required. Have reset modem and router. Have deleted all junk emails. Know it's not a Comcast issue as I am getting my Comcast emails on my cell phone via my BlueMail email app. (But cannot work on emailed documents on my cell phone.) The other 2 times this happened, email began loading after 10 days of no activity. No rhyme or reason. Have checked the box for a status update but reports come through via email... which is currently not accessible via Thunderbird. Why does this continue to happen? Please help!
