From: bruce on 4 Mar 2010 20:44 Hi. System A has postfix, and can relay successfully email through Gmail. System A is 192.168.1.56 System B is 192.168.1.59 System B has Postfix, and has the line relayhost [192.196.1.56]:25 I'd like to be able to have System B, relay it's mail through the configured Postfix on System A. When I simply try on System B, to send an email, I get a "Connection Refused:" err in the log file of System B. The docs imply that the Postfix on System A should be "open" to connections from other systems in the same 192.168.1.x subnet. There is a "mynetworks" line that's set to its default. Is there something else I missed on this. Thanks
