I can't speak for Inet, but in my place of work our enterprise e-mail is protected by a complex and expensive filter system. This sits between our internal mail severs and the internet (called the dmz - http://en.wikipedia.org/wiki/DMZ_%28computing%29), and acts as the edge server to our exchange organization (http://www.msexchange.org/articles_t...t-gateway.html).
Boring stuff aside, this system is designed to block spam and remove dangerous mail. It is auto updated from black lists provided from various sources.
We also manually ajust it ourselves, blocking spammers, undesirables, and crooked domains. We also maintain a white list where addresses and domains can be added to allow mail through unmolested.
Even with this, hundreds of e-mails a week are routinely incorrectly classified and blocked. This requires a manual release, and normally someone wouldn't even know unless they we expecting mail and it didn't arrive.
Staff can be notified via e-mail, as can the sender if the mail is auto blocked, genuine mail can be released. Not a good idea for staff, as they wouldn't want a notification e-mail every time an incoming spam message was blocked (several thousand a week). Good idea for the sender though.
Anyway, it's possible this is where many of the phantom e-mails are going.
