(now unsigned) how not to match a sub-subdomain

[Marc Risse]

Hello everyone,

will ".domain.com" match "b...@sub2.sub1.domain.com" or only 
"b...@sub1.domain.com" in transport maps? 
"parent_domain_matches_subdomains" is not set and I don't want it to 
match all subdomains on all levels.


Best
Marc
