Sendmail masquerade
Hi,
Please tell me what is sendmail masquarade and what is the use of it?
Its pretty confusing
..
Is it all about like when mail is sent from sender to receiver, the receiver cannot see the hostname/internal username of sender..
And I found they constitute various classes like class w, class M and class E.. What they all about mean to?
Please correct me if am wrong anywhere..
Please help..
