I leave Thunderbird running on my computer at home to do filtering and to handle spam. My account is an IMAP account. When I access that IMAP account using the ISP's webmail interface while at work, it seems that -- often -- the filtering and spam handling on my home machine halts. This might be because I manually delete obvious spam and "should be filtered" emails using the the ISP's webmail interface. The Thunderbird app itself (at home) keeps running, though. Has anybody else seen something similar? That is to say: Deleting messages on an IMAP account using the ISP's "native" webmail interface results in a separate instance of Thunderbird (running somewhere else, but at the same time for the same account) losing functionality? (not crashing outright, but filtering and spam handling stops) TIA! Home tech details: MacOS 15.3.1 (24D70) Thunderbird 128.7.1esr (64-bit)
