As others have said, it's a total misunderstanding. Mail coming from subdomains is a perfectly normal thing. For example, many big corporations and/or universities do not have a single top-level mail service for the whole entity, but they have separate mail servers at department levels. It's totally normal that you will see emails from [email protected]. Also take into account that many countries use two-level domain registration scheme - for example someone already mentioned UK, where you have *.co.uk for companies or *.ac.uk for universities. Also my country uses for example *.com.pl, *.edu.pl (not mentioning *.gov.pl !) addressing scheme - to be more confusing ;), in parallel to direct registrations in *.pl, and to geographical per-city scheme like *.krakow.pl, *.waw.pl, *.gda.pl etc. And please look at my email address as well :) -- Regards, Jaroslaw Rafa [email protected] -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
