It's very nice of you "being around". My knowledge about those things is very vulnerable, so there is no surprise many times I did some illiterate guessing. Thanks, still can't resolve the hostname. Perhaps will wait for Monday and contact someone. I did configure the exim4 and hours ago was a bit happy about that. Now it still does not work after purging the exim4. BTW, any suggestions about how to examine are sincerely welcome.
