Could you please post the contents of the return messages so I can work out where the problem is occuring?
Remember to cut out any email addresses from the text before posting and replace them with [My email] and [destination email]!
i am receiving e mails ok from this person but she is not receiving mine it comes back saying postmaster@mc3-s39 delivery notification status notification failure and we have emailed for months and on msn messaging thank for your reply
If no changes have been made to your email settings, I'd suggest your friend checks that their inbox isn't full. Sometimes, systems can stop you recieving email when you have too much stored.
