I am getting the following message when trying to send something via SMTP from one of our copiers. We've had it work from similar setups, and I am hoping that adjusting this timeout will make it work (perhaps latency or a slow connection is causing it to timeout).
Oct 19 16:47:13 mail postfix/smtpd: timeout after RCPT from unknown[xxx.xxx.xxx.xx]
Oct 19 16:47:13 mail postfix/smtpd: disconnect from unknown[xxx.xxx.xxx.xx]
Can someone point where I can adjust this timeout?
