Hello,

I'm trying to send mail:

Sending via mail...

gnutls-negotiate: GnuTLS error: #<process smtpmail<1>>, -15



Ein unerwartetes TLS-Paket wurde empfangen. == An expected TLS package

Small correction:

    an *un*expected TLS package has been received

As to your original question... no idea, sorry. Except  you could try
tcpdump or wireshark to spy on the conversation, perhaps there's something
to learn from it.

Could you check if mail works unencrypted first?  That could help narrow
down the problem.

Of course, sometimes these days SMTP servers don't support that.

I'm guessing the email is *not* being sent to the mail server's port 
number 587.  And, though there's not much evidence to go on, I'd guess 
again that it should.
