There are known issues with any IMAP servers having issues or lack of 
support for IMAP keywords. Usually, this means that the tags become 
local-only, for example, they are lost if rebuilding the database.

Suddenly losing the tags could happen if the server appears to be 
supporting IMAP keywords, but for some reason doesn't really handle them 
properly. It could also happen if the server does not support IMAP 
keywords at all, but happens to change the UIDVALIDITY for mailboxes. An 
example of this would be Exchange IMAP.

(In both of these cases, there are workarounds which could be 
implemented in MailMate to make it more robust.)

If you have a reproducible issue then I'll naturally be willing to look 
into if there is also a MailMate bug which can explain it.
