I would like for my webmail to delete my mail after Thunderbird downloads it (I have it set to IMAP not POP; correction from original wording), so that I will only be storing my mail on my machine.
However I can't figure out how to set this. All of the help I searched up references an account setting that isn't available on the version I have. (38.1.0/OSX). I've seen people reply to those walk throughs with the same issue I'm having, but haven't been able to turn up a solution or anything more recent than 2013. I'm an above average user but I'm not advanced. Is there something I have to do on the cpanel of my webmail to enable this? Or do I do it in Thunderbird?
