Here is the basics, ISPConfig 3.0.5.4p9, Centos 7 Perfect server setup via howtoforge. We have IBM mainframes on location that use IBM MVS SMTP CS V1R11 to send email to the server to be sent from there (RELAY) How in jumping christmas can I get the server to just allow the relay? Note: In all their infinite wisdom, I can not figure out how to tell this IBM monstrosity how to simply authenticate, so I need this thing to be able to send from the server without AUTH Debug snipet from Mainframe 221 e-server.ddci.net.datadallas.com running IBM MVS SMTP CS V1R11 closing connection EZA5200I 06/28/16 09:06:52 1> Connecting to IP: x.x.x.x EZA5198I 06/28/16 09:06:53 1< 220 ********************************* EZA5200I 06/28/16 09:06:53 1> HELO e-server.xxxxxxxxx.com EZA5198I 06/28/16 09:06:53 1< 250 mail.xxxxxxxxxx.com EZA5200I 06/28/16 09:06:53 1> MAIL FROM:<@e-server.xxxxxxxxxxxx.com:[email protected]> EZA5198I 06/28/16 09:06:53 1< 250 2.1.0 Ok EZA5200I 06/28/16 09:06:53 1> RCPT TO:<[email protected]> EZA5198I 06/28/16 09:06:53 1< 454 4.7.1 <[email protected]>: Relay access denied EZA5200I 06/28/16 09:06:53 1> QUIT EZA5198I 06/28/16 09:06:53 1< 221 2.0.0 Bye
Here is the snip from main.cf mynetworks = 199.xx.xx.xx/28, 127.0.0.0/8, 199.xx.xx.xx/32, 199.xx.xx.xx/32, 199.xx.xx.xx/32, 199.xx.xx.yy/32 the one ending in yy/32 is the mainframe I want allowed. But still gets EZA5198I 06/28/16 09:06:53 1< 454 4.7.1 <[email protected]>: Relay access denied
