Thanks. > You can compile from source if the RHEL4 postfix package does not suit your needs (source compiles of latest postfix offers more featues for example or get you mysql database support). Other than that I do not see any other advantage. Disadvantages to either method...none besides the rpm not offering the other features available. postfix has not had a security problem since one issue in version 1.x which is perhaps not too surprising given that Wietse is also the author of tcp_wrappers so you do not need to keep track of security holes unlike sendmail.
