Sent emails not received by Hotmail.

Emails sent from to a Hotmail address from my LineOne address stopped being received about 6 weeks ago. All settings have been checked by myself and by the Hotmail address owner. the addresses have been communicating with each other perfectly well for over five years. I can receive emails from the Hotmail address, however when sending from my end, although they are marked as sent, they are not received.

Any ideas, anyone?

I've spotted the problem. Take a look in your blocked senders filter. You have your own email address in there. If you take that out you should find sending works normally again.

Correct! I can receive but not send - yet TalkTalk mail is logging it as sent.

Ady, 

All connections / settings checked at both ends, no problem with other email addresses. Potential receiver is having no problems, and I can receive emails from them. Note that this little mystery first occurred a few weeks ago and I have been trying to track down the cause without success.

Meaning its just 1 hotmail email address that can't receive your mails?

Ady,

All settings checked and OK, no problems at all, and as noted I am receiving and sending to all other email addresses with no problems. It’s a mystery!

Hi 1Dunsden1, have you checked that your sending to other addresses? You've checked for filters in webmail?
