Pimping MobileMe #1: Expiration dates on folders

Well, MobileMe does not yet support the expiration of mails in folders. Especially for mailing lists, I want this feature. After let’s say 90 days the mails should be automatically deleted. I do not need to store mailing list contents for longer. So I took the nice tool imapfilter and wrote a config file that expires old mails from a selection of folders. I installed a cronjob on my web server that now automatically calls imapfilter every night. The config file (~/.imapfilter/config.lua) looks like this:

Myaccount = IMAP {
   server = ‘mail.me.com’,
   username = ‘your.name@me.com’,
   password = ‘yourpassword’,
   ssl = ‘tls1’
}


folders = {‘folder1’, ‘folder2’, ‘folder3’}


for k,folder in pairs(folders) do
   foldername = ‘Mailinglists/’ .. folder
   results = myaccount[foldername]:is_older(90)
   myaccount[foldername]:delete_messages(results)
end
