I receive about 6000 emails a year from customers and elsewhere (not including spam) and have been trying to deal with it by creating a main folder called /Archives and adding a year folder with a sub Sent folder and moving all inbox emails to those folders starting about March 1st. This keeps my inbox to less than the seemingly magical 5000 emails in the inbox number where clients like Thunderbird can operate without issues.
Is there any kind of automated functionality in SmarterMail that I don't know about that can automate that process for us and our customers? Perhaps set the Inbox and Sent mailbox to automatically move emails into those /Archives/yyyy and /Archives/yyyy/Sent folders once an email is, perhaps, three months old? This will keep our Inbox slim and nimble, and probably lessen the risk of corrupted mailboxes, which can really hose an SM install.
If this functionality doesn't exist I propose putting it on the wishlist.
