i already configure sendmail using webmin, when i run it, i only can send an email to local user that's mean user in my box only, when i try to retrieve an email from another computer using outlook express, it's failed. can anyone tell me what the posibble cause?
check /var/log/maillog as you try to send an email and let us know what it says
To retrieve mail from your linux system has nothing to do with sendmail
If you have mail on your system and you want to access it from another machine you should run pop3s or imaps. then configure outlook express to connect to the pop or imap server on the secure port and you can get your mail.
To have people send mail to you or a user on your machine by sending it to your machine you need to have the sendmail smtp server listening on port 25
check this with telnet
telnet yourmachinenameoripaddress 25
you should get a server response
To send mail to someone on the internet using your linux box as a mail server you must configure sendmail as an smtp relay server.

telnet: connect to address 192.168.128.4: Connection refused
just now i configured my sendmail server @mailserver.com become relay for another mail server @mydomain.com, when i try to send an email from client using outlook ,an error occured said,
the msg could not be sent becoz one of the recipients was rejected by the server. the rejected address was <email@example.com>.........serverresponse 550 55.1........
