1) delete the "X" inbox and create a new one (same name, with same settings;

2) create a filter that would intercept any incoming "x" email and direct it to a newly-created, alternative inbox (eg, "x rerouted").   So far, I can't find any way to 'target' "x" emails by the actual email account name -- filters only seem to target recipient or sender names, or subject headings, etc.

I have three different email accounts at my web host. After working flawlessly for many years, one of the email accounts (I'll call it "X") no longer comes in to its Thunderbird Inbox, but rather goes directly to my "Deleted/Local Folders" box. I've checked and re-checked all the account settings for "X", but I can't see any setting that would account for this behaviour. I would like to ''fix'' the problem, but - if I can't - I'm wondering if either of the following workarounds would be viable: 1) delete the "X" inbox and create a new one (same name, with same settings; or 2) create a filter that would intercept any incoming "x" email and direct it to a newly-created, alternative inbox (eg, "x rerouted"). So far, I can't find any way to 'target' "x" emails by the actual email account name -- filters only seem to target recipient or sender names, or subject headings, etc. Thanks, in advance for any help you can suggest.
