I’m using AWS SES for outbound e-mail and messages are only going to queue, it looks like Exim want’s to send e-mail not via SMTP Relay, but my port 25 is blocked on outbound. How can i fix that?
Global (and tried domain based) SMTP relay port is 587 from the beginning. Webmail works, Hestia mails work, but e-mail forwarding gives error to log and I think the same as the man who posted, that forwarding is not based on relay, try to use default 25 port, which is blocked by multiple hosting provider. Error in log is:
R=dnslookup T=remote_forwarded_smtp defer (-54): retry time not reached for any host for '[mailto-domain.tld]'
And the solution based on that topic is opening port 25. This shows the same for me, that e-mail forwarding is using port 25 instead of global or domain based SMTP relay. Am I right?
Without open port 25 there is no connection between servers, other ports are just for encryption such as 465 and 587. So in any case it is worth opening 25
Indeed it isn’t the solution, well, it will work because seems Exim is not using your smtp relay conf. If you configured a smtp relay using a port like 2525, it must work even if port 25 is blocked by your hosting provider.
Could you please show the output of these commands?
Last days I tried a lot of things. I ordered and set three new VPS at two provider, my last try was to comment on topics here. This afternoon I destroyed all the new VPS, which have problem, I delayed moving to one of them from current VPS. So now I can not show output, because all three VPS died. Thank for your time and answers. If anyone else will similar problem, please help @sahsanu and run that script. Info: I got this error on two DigitalOcean and one on Hetzner VPS.
