Sendmail + SMTPProxy

2001-07-24 Thread Fernando Casas 



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.

Use the source Allen:

 /* Receiver dastardly shrinks window. Our retransmits
  * become zero probes, but we should not timeout this
  * connection. If the socket is an orphan, time it out,
  * we cannot allow such beasts to hang infinitely.
  */

line 329 /net/ipv4/tcp_timer.c

its a bug fix.

May the source be with you.

Pete
