BT Email receiving emails OK but not sending

Hi All

Would really appreciate some help for an issue my Dad is facing. Normally i'd be over there looking to find a fix as he is not too savvy.

He says he is receiving emails OK but they are not always sending. He first had the error on 25/03 and then it cleared (after i told him to try a restart!) and he was able to send mails. But today he has said he has the same issue. I am including below the response he received first time round from "SYSTEMS ADMINISTRATOR" (so he says). NB: I am the intended recipient "Chris X" "Your message did not reach some or all of the intended recipients.

The following recipient(s) cannot be reached:

  'Chris X' on 25/03/2020 10:55

        550 spam, or phishing or malware.  Please check or edit your message and try sending it again. (6-1-3-2) ID (5E3A16DE0792B914)


Advice really appreciated so i can text him how to resolve.

Thank you!

Get onto Teamviewer and do it on his PC. Do try the "My server needs authorisation" trick

he has confirmed he has NOT received any undelivered messages that he did not send himself.

Thanks for confirming that.

It's still a mystery why BT thinks your dad's a spammer. Getting a new IP address may help so ask your dad to turn his router off for 30 minutes (or longer if possible). When he turns it back on he'll be assigned a different Internet address and that may fix things.

Note that disabling "My server requires authentication" can only help if your dad's ISP is BT. If he's with a different broadband provider then it'll make things worse and he'll end up with two sending problems.

Thanks Secret- squirrell

I will advise him to switch off router for a period of time.

noted on the "My server requires authentication" - His ISP IS BT
