Hi. Since the Thunderbird update in March/2026, my Bell sympatico.ca email is no longer able to send emails out through Thunderbird. No error messages but emails never get to destination (I tried sending to myself on both gmail and sympatico accounts). I receive emails without issue. I tested the sympatico from the web or my iPhone and it works. Seems something changed in T-bird back in March?

I validated the Outgoing SMTP server settings and all seems OK (See attached file for screenshot of settings). Any idea why and what changed to cause this?

Tx, Robert Ziwani

Suddenly, I can no longer send emails anywhere. I can still receive emails. I use KDDI, and I contacted them, but they said there are no issues with their servers. I can send emails using webmail. It seems to be an issue with Thunderbird. The message shown in the attachment appears, and I get an error. Please let me know how to fix this.

macOS Sequoia: Two copies of a large Inbox folder in Profiles folder

Hello,

In my Thunderbird Profiles folder, I can drill down to ImapMail. I see multiple subfolders prefixed with my imap server name. eg:

- imap.server-5.com 10.85GB - imap.server-3.com 8.83 GB

and so on. The datestamp on each is different.

Within the two examples above is a large Inbox folder taking up ~8.8GB.

The size doesn't concern me as much as the fact of having two of these. I'd like to understand what Thunderbird is doing under the hood here. Does it create new imap.server-#.com folders periodically as backup/recovery folders?

I'd like to recover space where possible but if these are protective measures, I could live with that. However, if it creates future folders and replicates 8+GB of data multiple times, I'd like to know what steps I can take to free up disk space.

Thanks,

I was just notified that my email provider is ending service after 30 years. I need to move all my folders and messages from my old Provalue account to a new Gmail account. Is there an easy way to do this? Can I just change the account name and password as well as the server settings? They are both Pop3 accounts. I also need to point 131 message filters to the new Gmail account. Is there a way to do this without having to rewrite all of the filters? Do I need to copy all of the folders and messages to the new account manually? I have 30 years of emails that I still refer back to occasionally. I need help, what do I do? Thanks in advance for any help I can get.
