I installed mail using the following comman: ee stack install mail
I can create mailboxes, log in and send e-mail, but when I try to send e-mail to one of the mailboxes from my gmail then receive error message:
Delivery to the following recipient failed permanently:
Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain webiq.lv by webiq.lv. [220.127.116.11].
The error that the other server returned was: 554 5.7.1 <info@…lv>: Relay access denied
