Re: Kolab 3.1 postfix relay access denied

[Tomas Kucera]

Hmm, that looks like it could but it looks like it is quite manual thing to enter all the possible email addresses.

I thought of some configuration that would enable the smtp such as some for example telco providers have their "open" smtp servers. You need to have a username and a password to be able to authenticate yourself but that`s it no email setup or anything.

There`s gotta be some simple way.

But I guess that this is not the appropriate mail group.

Well, if someone would have any idea for a solution, I will be happy hear that.

Thanks all that participated.

Kind Regards,
Tom.
