after a week of struggling with postfix i finally manage to configure
Dovecat+sasl+postfix
i can send and receive emails now the problem that i am facing is i
can use sasl for SSL IMAP however i can not secure my SMTP so that no
one can send mail bombing and spamming through my mailserver.
i know i can setup smtp with authentication so when every user sends
email smtp will authenticate username and password then accept email
but i can send email with out authentication. so please guide me for
the required facility.
actually one of my service provided providing us a mail facility and
they are authenticating with the same user ID password for smtp as the
credentials are created on main server. so i want to authanticate
emails in same way.
please help
please accept my appology for my poor english
