Router emails trigger error 553

Question

I sometimes want my Netgear ADSL router to email me it's log, but this now gives me Error 553. Netgear are baffled and so am I. Can anyone tell me what precisely causes the BTYahoo SMTP server to send 553? The router's email is effectively from me to me so it shouldn't trigger the anti-spoof trap.  Driving the BTYahoo SMTP server manually with TELNET seems to point to the MAIL FROM: command failing but I can't figure out why. If I manually send MAIL FROM: <me> and RCPT TO: <me> it succeeds, and I had assumed that is what the router does.  MAIL FROM: <someone_else> fails with 553 of course.  A friend who has the same router finds it works fine on another ISP, so BTYahoo are doing something odd.
BT's helpline didn't understand my problem at all.  I hope someone here does!.

I have to ASSUME that the router tries to send this email FROM me TO me, which should be perfectly acceptable to the SMTP server. I don't know if it does this because this email never gets sent forward and never gets sent back!  All I see (if I later access the router via its web interface) is the Error553 message in the log.  I asked a pal with the same router to try it. It worked with his ISP and the message HEADERS showed the To: and From: headers were [email protected] , but there's no way to see what the addresses were in the MAIL FROM: and RCPT TO: commands in the SMTP protocol (these are NOT the same as the "To:" and "From:" headers in the message body).  I haven't been able to get Netgear to tell me what addresses their router does use (should be [email protected]) so I am trying to work from the other end and find out what it is that the SMTP server at BTYahoo doesn't like when it throws a 553 at me.  I know it does this if I manually type MAIL FROM: [email protected] into TELNET.  I am certain this isn't a verification problem, it's a clash between the way BTYahoo's SMTP server is (now) behaving and the way the Netgear router is behaving.

Hi Peter. Welcome to the forums.
It is a verification problem, and the "From" email address should be enough to be honest, much like a normal email. What Netgear router is it ?
Can you say for certain that you have provided one of your @btinternet.com email addresses and corresponding password to the netgear settings ? (sorry for the obvious question).
Do you know if it has ever worked for you ? I expect there are other users of that router, so wonder if they have a similar problem.
Are you getting any response emails at all (e.g. in your spam folder, typically only accessible via webmail) for this problem ?
