i am not sure about what your mail setup really means it doesnt not look right to me but that maybe a understanding problem why not simply use getmail with spamassassin on your internal mailserver http://pyropus.ca/software/getmail/faq.html#faq-integrating very easy to setup if you can configure your outside mailserver using clamav with sanesecurity sigs and rbls as well as other postfix antispam features should do the job fine, do not use catch alls there, always have a valid recipient list you may bypass outbound virus scanning for internal mailservers ip or sasl user ( recommended ) -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
