This question has already been asked here but no satisfactory answers were given. Some say to go to trash folder and select mails one by one then delete; I will NOT select 250 mails one by one!! Others say to go to the mail providers web site... if I wanted to do that then I would not ask this question. Anyway, even if I do that (I'm not talking about g-mail, but other providers I have accounts with) the mails will remain physically on the android phone in the trash folder...
The problem is that in the default Android mail app, there is no Select All option for messages, and there is no Delete from trash option. There must be some way to do this?
Thanks
