Is anyone seeing non-delivery of btyahoo mail today? Two accounts are not sending even though the messages appear in the Sent folder.
Well I don't use BT or Yahoo, however my emails from my own domain to Google seem fine.
Do you get any emails sent back from the mail server saying it was unable to send the email?
I have had in the past emails delayed for some unknown reason by BT and I know it was BT due to back then we had two different connections with different providers and the other sent instantly where as the BT connection was just delaying them all.
Maybe the destination mail server is blocking the emails due to it thinks its spam.
So its worth looking everywhere both sides.
