Delete multiple emails from email server (pop)

Question

I have to delete emails that are older than six months and bigger than 1mb from multiple accounts, and my email webclient doesn't allow me to filter by those at the same time, so I'm looking for a way or tool to do it.

I tried adding the accounts to thunderbird (latest build), and use custom filters, but when I try to run the filter, thunderbird doesn't delete those emails from the server.

Any suggestions?

Answer 1

Set up the account as IMAP then sort the emails by date and size. You can then easily delete the messages that fit your criteria.
