Relayhost issues in multiserver config
I have an ISPConfig multisite installation and I'm having issues with relayhost configuration of slave servers, I'll start explaining my configuration, I have three servers configured in a multiserver config, all of them are ubuntu 14 with a LEMP configuration, the ISPConfig is v3.1.1p1, I have configured the sendgrid servers as relayhost on the ISPConfig configuration for each one of the servers, but when i check on the postfix config it gets configured only on the main server
root@s1:/usr/sbin# more /etc/postfix/main.cf |grep relayhost relayhost = smtp.sendgrid.net:587
root@s2:/home/ubuntu# more /etc/postfix/main.cf |grep relayhost relayhost =
root@s3:/home/ubuntu# more /etc/postfix/main.cf |grep relayhost relayhost =
I've changed the configuration on the slave servers to none relayhost, waited several minutes and configured the relayhost back and worked for few days, but later it went back to no relayhost.
Could you check this please? is really anoying when i can't send emails from the slave servers
