Using external DNS and mail servers - why do e-mails still end up on hosting server?
When a domain uses an external DNS server and external mail server, shouldn't none of the e-mail make it to the server hosting the web site?
It's been like this for over a year, so I don't think it's an issue of slow propragation of the DNS info. And most of the e-mail does get properly routed to the external mail server. But a bunch of e-mail still ends up in the catch-all mailbox of the hosting server. And it looks to be all junk mail. Is this due to the way spammers send junk mail?
