For example the mx query might return:
10 mx1.exampledomain.com
20 mx2.exampledomain.com
0 exampledomain-com.mail.protection.outlook.com
For example I'm interested in the *.outlook.com domain - I want to know
if it is in the list of mx's - but I am essentially comparing a list
(the list of mx records) with another list (of whitelisted domains)-
which I guess is not possible.
Have a look at the foreach/forany expansion conditions, and to
trim the mx priorities away from the mx lookup try the map expansion.
Thank you very much for that suggestion - somehow I never noticed the
foreach/forany operators. As to the mx priorities, I just used the mxh
type lookup which removes them - so it worked out perfectly. I've
enclosed below what I ended up with - in case it helps others:
domainlist no_extended_callout_mxs = *.fussy_mx1.com : *.fussy_mx2.com
condition = ${if forany {${lookup dnsdb{>:
mxh=$sender_address_domain}}} {match_domain
{$item}{+no_extended_callout_mxs}} {true} {false} }
