I have just installed Sylpheed email client.....I have it setup to monitor my gmail accounts...2 of them
I have noticed an additional mailbox ??.....I am actually not sure if that is what it is......the screenshot below shows "Mailbox (MH).....then a list,...Inbox,sent,drafts,queue,trash and junk....all are empty.
The 'tree' then goes on the show my email address, followed by Inbox and the rest of my folders etc
The "Mailbox (MH) perturbs me.
Any clues ?
