Hi
Any emails I send to hotmail accounts are returned undelivered with the following message
550 OU-001 (COL004-MC2F2)Unfortunately, messages from 78.***.17.** weren't
sent. Please contact your Internet service provider since part of their
network is on our block list.
Any ideas how I resolve this?
Solved! Go to Solution.

@MI5 Yes being an ex business user we were still being marketed to swap to adsl etc until the closure of the business last year . Now we are all on consumer contracts .
