Need RCPT command error

mrf3049 — Sat, 28 Feb 2026 16:28:38 GMT

My internet connection is fine and I can receive emails with TalkTalk webmail but I cannot send or reply to received emails. I get a '503 5.5.1 Error need RCPT command' and if I try again a '503 5.7.1 Reject for policy reason' I have now spent nearly 3 hours with help and support trying things but the problem remains. I'm exhausted and wonder does anyone know where this problem may suddenly have appeared from and has anyone had this problem and had it resolved ? Technical support appear to be floundering and I'm insufficiently adept with systems to know what I'm doing if I make adjustments.

It sometimes seems to happen if the server misinterprets what you are trying to send as Spam, @mrf3049.

The forum search engine will take you to threads on this topic - select the "forums" option or you won't get many answers. I typed in the number of the error message to see what came up.

Unfortunately staff are not back on here to offer support before Monday, @mrf3049.
