   Hello, i followed this nice guide and everything seems to be working fine - https://www.howtoforge.com/perfect-...-bind-dovecot-ispconfig-3.1/#-install-mailman
   
   But my ISP blocks port 25 and requests clients to only use either port 587 or 465. while using their SMTP server name - smtp.ltk.lv
   
   What would be the correct way to configure postfix? using mynetworks?
   
   Thanks.

   You can set the relay server in ISPConfig under System > server config.
   
   Use as relay server value: "smtp.ltk.lv:587"
