I can receive an e-mail from a paraticulair address but I can't send an e-mail to the same address without getting a delivery failure. Even if I reply to a message sent I still get the error message
If it is only one email address you are unable to send to, the problem is likely with that party's ability to receive email. If you have more than one email account, have you tried emailing this person from a different account and does it result in the same error?
If you copy and paste the delivery failure message here, we may be able to find out what the problem is. I would recommend removing any email addresses from the delivery failure message to keep these private before posting it here.
What error do you get? I remember Shaw having an issue with a few symbols in an outgoing email, but that may have just been webmail too.
It is just this one address
The following message to <> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 550-'5.1.1 Recipient address rejected: User unknown'
That says the email address doesn't exist.
If the person you are trying to email, is using Outlook, it is very possible they entered their email address wrong into their email program, so you can't reply.
Can you contact them in another way, to confirm their address?
