Searching within all your mail takes quite some time.
Con Not possible to rename the accounts
You always see a mail address as the account name, it's not possible to change that.

It's not possible to sort the mail list, so you will always see the mail 'date sorted'.

Con No spam filter

Con Blocks and freezes all the time
Con Saves passwords in plain format
Con Too much bloat
some people dont like the simple design of slypheed so they forked it and created claws mail but it has become so bloated since itsbeginnings.

This takes more space on the HDD.
Con Interface looks old and setup is not easy
The icons as well as the rest of the interface look like an application from the early 90's, with this there is also no easy setup options built in like the more modern e-mail clients.
