One might think that at first glance since most red-dot messages in the 
screenshot are listed in bold text, but look at the 1st message in that 
list: blue dot.

Also: mid-list, 3 messages, non-bold text (meaning they've been read) 
but they have a red dot...

It means that you use another client in addition to MailMate with that 
source account and that the other client handles message deletion in a 
classical IMAP mode. This means that messages get marked with the 
"\Deleted" flag when the user deletes them, but do not REALLY get 
deleted until the mailbox or (if the server & client support the UIDPLUS 
extension) the individual message is purged. Some servers auto-purge 
mailboxes or individual \Deleted messages based on various criteria and 
some clients do as well, although some client+server combinations will 
never purge anything unless the user explicitly commands it.

So: a red dot in the "Read" column means that something other than 
MailMate marked the message for deletion but has not yet told the server 
to purge it.

The mechanics of handling message deletion and presentation of 
recoverable "deleted" messages vary broadly between IMAP clients. 
MailMate uses a very conservative approach of not purging messages it 
did not flag \Deleted, although I don't know how it manages that on 
servers without UIDPLUS support (which was a requirement for early 
versions of MailMate.)
