Greetings, Maybe this question is not referring to security, but is very useful for to work in a domain with NIS and NFS. I have one server that is the principal server for e-mail, ftp, NIS and NFS for the users in te network local. The server and workstations have Linux Red-Hat; the users can read their mail in any worksation without to make a telnet to server principal; but, when they send a mail to somebody, in the section of FROM appear user@localhost.localdomain. Then when the user that receive their mail not know the e-mail direction correct of "user". How can I do for to make that appear the e-mail direction of user correctly when they send a mail to somebody?? by example: user@server.domainIP I will be appreciated your help. Thanks! ------------------------------------------------------------------------ To unsubscribe email security-discuss-request@linuxsecurity.com with "unsubscribe" in the subject of the message.
