My Local Folder is pretty full. I do try to compact my inboxes on a regular basis.
Definitely A, but still can't see anything in the log file that shows anything odd. Which leads me to this.
Would I lose anything (actually lose anything rather than 'is it a risk worth taking', I mean) by uninstalling Thunderbird then reinstalling or would it go Pete Tong?

Before you attempt to re-install Tbird, I suggest you try bypassing it completely by either (best) testing a direct connection to the IMAP server, or (second best) installing an alternative lightweight mail client such as claws. (I use claws all the time).
I'm assuming that you are using IMAPS and not plain IMAP so you cannot just test the connection with telnet, you would need to use openssl. So try the following (replacing imap.host.name with whatever your ISP's host is called):
1. openssl s_client -crlf -connect imap.host.name:993
If succcessful you will see the message "CONNECTED" followed by a lot of details about the certificate in use (see my test to my server below)
Now login with your user name and password
2. a001 login admin@rlogin.net password
(the a001 bit is just a tag, it can be anything you like)
If succesful, you will get a message like:
a001 OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SNIPPET=FUZZY LITERAL+ NOTIFY SPECIAL-USE] Logged in
Now list the mailboxes
3. a001 LIST "" "*"
You should see something like:
* LIST (\HasNoChildren \UnMarked \Junk) "." Junk * LIST (\HasNoChildren \UnMarked \Drafts) "." Drafts * LIST (\HasNoChildren \UnMarked \Sent) "." Sent * LIST (\HasNoChildren \UnMarked) "." Queue * LIST (\HasNoChildren \UnMarked \Trash) "." Trash * LIST (\HasNoChildren) "." INBOX a001 OK List completed (0.002 + 0.000 + 0.001 secs).
Now select a mailbox to check
4. a001 SELECT INBOX
You should see something like:
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft $Forwarded *)] Flags permitted. * 88 EXISTS * 0 RECENT * OK [UIDVALIDITY 1567098095] UIDs valid * OK [UIDNEXT 1025] Predicted next UID a001 OK [READ-WRITE] Select completed (0.001 + 0.000 + 0.001 secs).
(So in my case I have 88 messages in my admin mailbox)
If that all works OK just logout
5. a001 LOGOUT
and you should see:
* BYE Logging out a001 OK Logout completed (0.001 + 0.000 secs).
All the commands above are noted in the RFC for IMAP at https://tools.ietf.org/html/rfc3501
If any of the above fails, or takes far too long, or you get error messages, note the failure message - it will be useful in discussions with your ISP. In my test all the responses from my server were almost instantaneous.
If you don't fancy trying any of that, just install claws and configure it to connect to your ISPs server. Now connect and go to "Tools" -> "Network log" to see details of the network transactions. Again any errors shopuld be fairly obvious.
