Regardless of what the warn should or should not do, it is in fact the

the ACL, it is as I copied it.
It's the use of the "require" verb. From the docs:
If all the conditions are met, control is passed to the next ACL
statement. If any of the conditions are not met, the ACL returns
“deny”
You'll find that in Ch40:

Hi Graeme, thanks for the reply,
I am unsure that I follow it completely. In my understanding, the
require verify should only apply if the condition is met.
Not so. The ONLY condition that applies to that 'require' is the one
immediately following it on its OWN line...
How it should behave:
If recipient domain is in /etc/staticroutes then do a recipient callout
verification. If the verification fails with a permenant error, reject
message. If the verification fails with a temporary error, accept and
queue for retry.
No recipient verification callouts should occur if the recipient is not
in /etc/staticroutes (ie the condition is not matched).
This is not what happens because recipient verification callouts are
happening (and failing) on domains not in /etc/staticroutes.
Regards,
Colin
Re-write it this way (fix MUA line-wrap!):
=====
deny
## do a check for presence in static routes file
condition = ${if eq {1}{${lookup{$domain}lsearch \
{/etc/staticroutes}{1}{0}}}}
## .. carry-on if found, bail-out if not found
!condition = verify recipient/callout=30s,defer_ok,use_sender
## having arrived here IF found in the static routes file...
## attempt recipient verification by callout
## trigger the 'deny' entry verb if callout FAILS
## ( the '!condition' of success)
=====
