Hello i am unable send email after configure per domain relay. If anyone pls help me out to configure SMTP Relay per domain.
What does Exim’s log say? The log is here /var/log/exim4/mainlog
here is the log message ::

That’s not the first message:

after remove the DOMAIN BASED SMTP RELAY msg delivered successfully . No template remain default
I see two things:
1.- Your server sent the mail directly once you removed the smtp relay.
2.- You modified Exim’s conf and you are not using the default Hestia’s conf.
Bro I have very little knowledge in Exim.
My colleague did some changes after its not working, then revert again to default file.
Anyway how could i will make it work & possible to share my config files.
If you are now using the default exim’s conf for Hestia, then just configure the smtp relay in Hestia with the data provided by swift and try again. I want to see the first message in the log when you try to send again a mail using the relay. Also, your provider should let you know the changes you should do to spf, dkim selector…
Here is the log::

Are you sure that the right host for the smtp relay is swift.telnet.net.bd?
Have you openned the outgoing TCP port 2525 in your firewall? Could yo do a telnet to it from your hestiacp server?
By example:
$ telnet swift.telnet.net.bd 2525

smtp relay is swift.telnet.net.bd its in production each day we send 2000+ zabbix notification email
I can’t see the first error message yet, maybe it is in one of the archived logs.
Show the output of these commands:
exim -bt [email protected]
echo "Test body" | exim -v -odf -f [email protected] [email protected]
Please, when pasting the output here in the forum, select the pasted text and Ctrl+e or click on button </> to format the output correctly.
Well, reviewing your error message:
retry time not reached for any host for ‘xxxx’
means that exim is not trying to send anything “until” the retry time for that “xxxx” domain is gone. It means that you surely have some emails in your exim mail queue from time ago pending to send to that domain.
You can review your mail queue with:
exim -bp
and you can force a delivery of them, ignoring retry time, with:
exim -qff
Then, if any of them is really sent, you can show the exim log to notice which new error appears in it with the correct description that comes from your smtp relay server and not from your own exim due the retry time not reached.

I thought sel.com.bd was an external domain, but it looks like it’s a local domain.
Anyway, looks like exim can’t found a valid authenticaton mechanism:
I want to see the AUTH mechanisms announced by the smtp relay, execute this command and show the output:
