when i am send a mail to other account my email address showing "username@domainname@domainname". plz help me



How are you sending email - from Usermin on port 20000, Squirrelmail, Roundcube, Outlook, Thunderbird or some other program?

its working perfectly in usermin port 20000 and outlook. when i am sending through squirrelmail its shows username@domianname@domainname

when i am logging through squirrelmail (name : username.domainname) squirelmail is opening but if type full email address its not opening

You may need to set the actual From address in the Squirrelmail settings in order for it to use the correct address.
