after hours and hours I have no more ideas what to do...
I want to set up a scalix-installation, to send mails over an external smtp-server.
some details:
smtp.isp.de --> the external smtp-server
imap.isp.de --> the external imap-server, where I want to receive mail (with fetchmail)
user@domain.de --> user to gain access to the external mail-server, and also user in my scalix-environment (my mail-domain is domain.de)
I really don't know how to set up scalix/sendmail to be able to send mails to "the internet".
I've read the wiki, 100000 of Forum posts, I asked google 10000000 times.....
but it is still not running.
What do I have to configure (sendmail....)
Right now I don't want to say what I tried/did, cause I hope someone can give me a step-by-step guide, what I have to do.
I would be really happy, if in the end scalix understands what I want

Greetings
Florian
