Recently i installed HestiaCP on my server, and everything is working well. (You have a fine product here).
The only thing i have difficult with, is the mail server - which can receive email from everywhere, but can send only internal mails. if i try to send it outside, it’s not reach. in logs i can see connection time out, and later i receive mail:
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:…
Tried to check DNS records, and it’s seems to be ok.
Telnet to google in port 25 failed, but does succeed in 465 or 587.
I’ve managed to connect outlook to my mailbox - and again - i can send to myself, receive from everywhere, but can’t send outside.
Check in this forum and other places, and i must ask this question:
Do i must configure rely SMTP server if i want to send email out’ or it can be done all by my own server?
