Sendmail + SMTPProxy



Hi, i´m having some trouble with the mail system. I´ve have a Firewall machine that´s running Postfix on the loopback interface (lo) and a SMTP proxy (smtp.proxy is 1.1.3) on the public IP. Behind that Firewall i have a machine running SENDMAIL 8.9.3/8.8.7, with AMAVIS 0.2.1 (not perl). The problem is that sometimes, it´s like the connection gets lost (perhaps time out i think?) and i believe that it is a problem generated by the SMTP proxy because when the server recieve mail from machines on the lan this doesn´t happend.
Any ideas?
Advices??
Can i use postfix to forward ALL the incoming mail to the server with sendmail?????
Here it´s part of the log. May be it´s useful for someone.
Thanks in advance.
