Some members of my yahoo group don't receive some of the mails even if their yahoo id is registered. why?

Question

my group has a mix of email ids. some yahoo and some are not. this problem is observed sporadically (no pattern).

Answer 1

This sounds like a technical issue that could be causing the problem.  I would recommend getting in touch with a Yahoo Groups customer service representative as well to see if they can help figure out what could be causing the problem.

Answer 2

it could be a server issue on their end, or yahoo's end. it could be the members own mail provider issue and the settings they have. they'll need to contact their server IP provider as well as yahoo
