Did you overlook plain "debug"? You will need "debug: yes"
I did! Doh! Thanks so much.
Those logs are more illuminating, but ... not quite illuminating enough.
When Thunderbird connects it opens all of the folders, and it seems, keeps a connection open. I can see it doing `open: user phil opened XXXXX`.
But when Android mail connects, I get several `fetching user_deny.db entry for 'phil'` and then:
2023-08-02T22:41:39.106718+00:00 virt cyrus/imaps[3012571]: extractor_destroy((nil))
Sometimes it'll open one mailbox, and then just hang for a long time with lots of `fetching user_deny.db entry` entries... and eventually (~2 minutes) will get a extractor_destroy message.
What's weird is while this is far more common on cellular data, it also sometimes happens on wifi - the same wifi that my laptop is using fine.
I did a tcpdump and while it's hard to know for sure since everything is encrypted, it seems like the phone sends an unexpected FIN. I'll keep digging.
