Failed 5.4.3. Router server Failure

[#1]

I noticed today I had about four random e mails when I usually have about 54. I have an e mail account with BT and Yahoo both these are returning mail I have sent to my PN account stating Failed 5.4.3. Router Server Failure. Also all e mails to my bt email are supposed to automatically be forwarded to my PN account but not one has since midnight Anyone any idea why I am getting the odd random e mail but the majority are not getting through ? Any help would be appreciated Many Thanks

As BT use Yahoo for email, the two accounts are likely to be sending via the same infrastructure.  A 5.4.3 Routing error is generated by the sending server so you probably need to contact Yahoo to resolve this.

Unfortunatley this goes beyond that now as I have asked two people with non BT related e mails and all have been bounced back I am actually receiving no e mails from anyone so this is PN not Yahoo or BT

Can you get the full bounce message from one of the people trying to end you email?  Obviously they can't email it to you
Are they sending to a <user>@<account>.plus.com address or do you have a domain name of your own?  If the latter, are the MX records correct?

I am just onto support now but I have a domain name but nothing has changed I even got Ebay to send an automated response to my e mail and that didn't arrive There is a 30 minute wait on the phone so I am trying to connect to live chat.I have been waiting for twenty minutes now they say I will transfer you and there are eleven customers in front of you it took twenty minutes for 6 I should have waited on the phone whats going on PN ????

Now its thrown me back to the opening screen Give me strength  I didn't expect this fro PN

[#7]

Two quoted Failed; 5.4.3 (routing server failure)
One quoted security issues and Microsoft would not be re trying to send ?

[#8]

I have now been on line 36 minutes waiting for a response with still 8 customers in front of me !!!!!!

This rather implies that the problem is NOT with PN's services.

Emails from whom using which mail providers?

[#10]

Looks like the OP's domain had expired. I believe the issue is now resolved.

[#11]

emails wont go out to vip@bingodiomond.com

Check you're using the correct address - the domain 'bingodiomond.com' is not currently owned by anyone (you may have made a simple typo when posting to this forum, or you may have mistaken the correct address in your failed emails).

@elizabeth2 Welcome to the forums.

Is the domain given a typo - as written it doesn't appear to exist? It does exist if an "a" is substituted and relay.plus.net will connect to it..

Since you posted in this topic I assume you got a 5.4.3 error when trying to send. Is that correct, and did you get any other information?
