Hi All, I am new to perl & I need to send mails using my program, So I choose mail:mailer. My machine dns name is "helpdesk.luminalto.com". In my program, For my from & to addresses , This DNS name is getting attached(suppose if I give "root@helpdesk.luminalto.com" as from address, It is taking as "root.luminalto.com@helpdesk.luminalto.com", If I give "root" as from address, It is taking as "root@helpdesk.luminato.com") automatically at the exicution time which causes failure in the mail sending. Can any body Suggest me how to get rid of this problem. Thank you, Sudheer Tumu.
