Thanks for the quick answer!

Yes, an HTTPS-Proxy

A friend of mine is hosting my homepage and the e-mail-boxes for the
homepage. Actually it is not mine server, but it is the server I use to
send my mails. I would say it is the mailserver of my ISP.

I tried both commands:

nc -v 194.97.54.34 25
194.97.54.34: inverse host lookup failed: Unknown host
(UNKNOWN) [194.97.54.34] 25 (smtp) open
220 baloney.puettmann.net ESMTP Exim 3.36 #1 Sun, 06 Jan 2008 10:04:04 +0100

telnet 194.97.54.34 25
Trying 194.97.54.34...
Connected to 194.97.54.34.
Escape character is '^]'.
220 baloney.puettmann.net ESMTP Exim 3.36 #1 Sun, 06 Jan 2008 10:04:24 +0100

It works :)

If I understand it correctly, I have to send my mails with exim to the
mailserver of my ISP, and the server directs them to the recepient. Or is
it possible to send them without using the mailserver of the ISP?

That's why I asked :) Say me, what information you need, and I gave them
to you.
