So, two last questions from me then...

1. If this is put off until after Maildir is working correctly, will it be:

a) just as hard to fix as before


b) harder to fix, due to maildir now being a new factor to consider?

As long as fixing maildir first doesn't actually make this much harder 
to fix later, then absolutely just focus on maildir...

2. Will Maildir only be for POP accounts? I really can't see where/how 
it could be used with IMAP accounts...

This is getting OT, so I won't pursue this question any further, but I 
will be posting a new question about IMAP soon (since Thunderbirds IMAP 
capabilities is about the only area where I still have lots of issues)...
