A message I sent from work (Beverly Public Library) was returned to me, indicating that our server is blocked. I checked our mail server ip (North of Boston Library Exchange, a public and college library consortium, 18.104.22.168) and it is not blocked. But the server between us and the recipient is blocked. Should this happen? I contacted our administrator but since we aren't blocked, what can she possible do? Any way for us to resolve this problem? Does this happen often? Can we choose which servers our mail is routed through? I always assumed it was the luck of the draw.
Thanks for help.
Here is the returned mail with headers:
