hello, I had a message saying my inbox was full, so I deleted many emails, and then emptied the trash. Now, the message comes up that the trash bin is full (even though it shows empty on my machine) and people trying to email me report emails are bouncing back. The odd email is getting through

Hello, what mail service are you using with eM Client? Are you using a POP or an IMAP account, unless you’re using IMAP the messages are only removed locally, but a copy can be kept on the server, to avoid this setup the POP account based on your preferences and mailbox size in Tools > Accounts > Your account > POP > Server settings.

You can chose to remove items when removed from trash in eM Client or to keep a local copy only and remove items automatically from the server.
