Comment (by rockbmb):

 I received this email from Microsoft not long after I sent an email to
 libraries at haskell.org:

 Delivery has failed to these recipients or groups:

 Haskell Libraries (libraries at haskell.org)
 Your message couldn't be delivered. Despite repeated attempts to contact
 the recipient's email system it didn't respond.
 Contact the recipient by some other means (by phone, for example) and ask
 them to tell their email admin that it appears that their email system
 isn't accepting connection requests from your email system. Give them the
 error details shown below. It's likely that the recipient's email admin is
 the only one who can fix this problem.

 I'll try again.
