My email client or In premise Mail Gateway server is unable to send mail via Connect Xf Mail server: Connection Refused

Parameters to check and the remedies

Parameter Steps
1. Check the outgoing mail flow
  • Check the smtp routes on the client's gateway server using the following command:
cat /var/qmail/control/smtproutes

Get the MEM URL/IP from which the mails are relyed outside

  • If there is no access to the customer server then use the following commands to check which server is getting used to send mails to outside domains:
cat /var/log/messages | grep "mail from" | grep <customer domain name> | more

This will show the entries of mails sent from indiacom users to remote domains.

  • On the MEM server from which the mails are getting relayed check if the customer ip is blacklisted
cat /mithi/mcs/modules/mithi-bl/conf/server/mithi.system.blacklist.fw.conf.sh | grep <customer server ip>
  • If the ip is listed in blacklist remove it from the file:
vi /mithi/mcs/modules/mithi-bl/conf/server/mithi.system.blacklist.fw.conf.sh
  • Add it in whitelist
vi /mithi/mcs/modules/mithi-bl/conf/server/mithi.system.whitelist.fw.conf.sh
  • Restart the firewall
/etc/init.d/iptables restart
  • The IP blocking happens due to the rate control.
