Hi: I just want one favor regarding mail server if anyone can advise for me. I have a small company of 100 users and have implemented Postfix mail sever when we were 10 users in normal P4 machine. Now a days users are facing lot of problem like mail is going in QUARANTINE, SPAMING AND MAIL GOT DISCARDED. Which is not good for our organization.
I want to implement such mailing system from which I can get rid of this type of problem and mail runs with 100% accuracy and no such incident happened. Please advise which is the best mailing system which I need to Implement in our organization.
