Regarding handling suspened email accounts

Hello,

I have the following router setting or validating suspened accounts and
the perl validation is working fine.

suspendedcheck:
# check if sending user is suspened
driver = redirect
domains = +local_domains : $primary_hostname
condition =${if eq
{${perl{is_suspended}{$domain_data}{$local_part}}}{yes}{no}}
allow_fail
allow_defer
allow_freeze
data = :fail: Suspended account
no_more

But the problem is this email is still sending to transport and delivering
to the inbox. Do it suppoes to simply fail ?

Regards
Sherin A

First thought: it's not processed at all.

Do a debug run and check, if it's really used:

exim -d externaldomaintest@mydomain.com < /tmp/mail.fail

use the suspended address, fake a mail to that address and watch the
routers list to be processed. You can see, if the condition you created
really ->yields<- a "true" .

Best regards,
Marius

Consider adding a -N to that line, too.

Hello Marius,

You saved the day , removing {no} from the condition fixed the issue.
Thank you Marius and Jermy
