Hotmail is notorious for silently deleting
mail. Had a similar problem
many years ago when working with a database developer who was working on
the company's electronic booking system. The system sent out
confirmation emails when people booked onto a course. However, we were
getting complaints about confirmations not being received. On further
investigation, we discovered that ALL of the affected people had Hotmail
addresses. Further testing showed that Hotmail was silently deleting
the automated emails, but manually sent email (i.e. from a regular
client) worked fine. Never worked out what Hotmail didn't like, but it
was highly annoying that it arbitrarily deleted email. Hotmail didn't
even place them in the spam folder, they were simply deleted.
Only surefire solution is for those affected to ditch their Hotmail
accounts. Anything else will work fine.
