Assuming you're using IMAP:
Go to Mail.app > Preferences > Accounts.
Choose the mail account having problems.
Switch to the tab mailbox behaviour.
Disable the checkbox "Store deleted messages on the server".
If that doesn't help, revert these steps.
Choose your Trash mailbox.
In the Mail.app menu > Mailbox > Use this mailbox for > Trash
If that didn't help either, please provide some info on the account in question.
