Only 5 domains are looked at until Thunderbird stalls...why?

jimtippins

I have a Postfix/Dovecot server that hosts 10 of my domains from one IP.

When you open Thunderbird, it checks the domains you have preset. I have two. This happens immediately, especially if there is no new mail on the server. Everything works fine.

If you have other domain mailboxes open, and I have eight more, and you click the inbox on each one, Thunderbird stalls at the fifth mailbox, regardless of the inboxes' selected order.

tail -f /var/log/mail.log - confirms this.

I have reset or modified everything I can think of. My server is not throttling Dovecot.

This must be something internal to Thunderbird, possibly related to only using a specific mail server IP for all domains.

Google AI suggests assigning a unique local IP alias to each domain on my server so Thunderbird thinks it’s talking to 10 different machines. This seems extreme.

Any solutions?

No response from the developers?

"Stall" is too generic. What do you see in Thunderbird UI, status bar or activity manager?

p.s. this is support - developers typically are not here.

Stall seems appropriate. I fully described the issue. And if the developers don't look at support forums, something's amiss.

Well, a developer isn't going to guess either. So you can continue, or not.

  • Is this imap or pop?
  • What is seen in Tools > Activity Manager or Error Console?
  • A developer will want to see logs https://wiki.mozilla.org/MailNews:Logging - which, if you are running your own server, you can likely read to get a sense of what Thunderbird is seeing.
