With Avast VPN secureline active (5.25.87922) no mail can be sent.
Mail can only be sent with VPN secureline deactivated.

Interesting, you’re the 2nd person here that mentioned this problem. I assume you are using mail clent software that’s separate from your internet browser, and that you have working VPN internet connectivity otherwise. If so, it wouldn’t be related to the VPN protocol that Avast is using. I would recommend going into online chat with an Avast tech to determine the problem.
