1und1 mail problem #227

Closed webbird closed 10 years ago

webbird commented 10 years ago

Testmail is not working on 1und1 servers since v1.0.2.

webbird commented 10 years ago

Problem seems to be that 1und1 uses STARTTLS, which means port 25 and switching to TLS internally.

I am still having problems to solve this, so I have to postpone it.

Using the correct configuration, mail is working on 1und1.

Do NOT enable SSL, you need to have a valid certificate in this case! Just use basic configuration. In fact, there is no need to use encrypted transport here, because the servers are located in the same server pool and communicate internally, not over the Internet.
