Hi, All! Thanks to everyone who replyed on this message. I think problem is fixed now, and I would like to share my little experience. [ Hopefully people with real knowledge after reading this oversimplified nonsense may decide to put together FAQ with a bunch of examples how to really setup smail/mailreader for ordinary user :) ]
The fatal error message like: 550 '<[EMAIL PROTECTED]>' sender address target 'linuxbox.domain' is not a valid e-mail domain. is coming from the unavoidable stage of mail post protocol: MAIL FROM: <[EMAIL PROTECTED]>, which is caught by domain and rejected. It looks like that for some reason the domain where my box is sitting don't like the idea of every node sending and receiving e-mails. So probably there is a list of eligible nodes. (true?) In such situation domain provides central e-mail service for everyone, and I have official e-mail address "[EMAIL PROTECTED]". In my particular case the environment is friendly, and everyone is allowed to forward mail from "[EMAIL PROTECTED]" to any node, where he prefers to read e-mails. But in any case the solution is to "fool" program that sends mails on Linux Box so that it will generate line (for all users of linux box, not just me): MAIL FROM: <[EMAIL PROTECTED]> instead of MAIL FROM: <[EMAIL PROTECTED]> For Mail program (package mailx) it is done in file: /etc/smail/config visible_name=domain # !! HERE !! fake name if you wish... more_hostnames=localhost -domains hostnames=linuxbox.domain # here is the true name For EXMH/MH program one need to modify: /etc/mh/mtstailor .... localname: domain .... There is also file /etc/mailname - but I failed to understand how it matters in all this business.
