Hi All, I'm having some problems getting postfix to relay mail. I'd appreciate any tips. Perhaps there are some settings which I may have missed, somewhere. The postfix mail server is on VLAN 250 (192.168.250.0) whilst I have several other users on other VLANs (e.g. 91, 92, 93, etc... 192.168.91.0, 192.168.92.0, 192.168.93.0, etc...). So, if I had a PC sitting on VLAN 91 with IP 192.168.91.1, I am unable to relay mail BUT checking mail via POP3 works fine. In /etc/postfix/main.cf, I have set the following:- mynetworks_style = subnet mynetworks = 168.168.91.0/28, 127.0.0.0/8 Do you know what setting I may be missing? Thanks.
