I haven't received any mail for 2 days on one email address, my busiest one, it is being passed by my forwarder - so it vanishes somewhere here.  I am beginning to get a feeling of Deja Vu.

It's beyond me why anyone would depend on Plusnet for email.

[#5]

I have received NO e-mail via my plus.net account. I use a mail forwarder which sends my mail to both my plusnet account and also a yahoo account.
So I know that all the e-mails on Yahoo should be coming in via Plus.net and yet nothing has been received.
My forwarding service is now warning my of delays as follows (edited to remove specific addresses)

Did this just start today? Whereabouts are the e-mails coming from? Are e-mails coming through from UK based ISP's or well known providers (like GMail)? It's possible it might be related to this. Have you tried e-mailing yourself?

Probably, ALL of my emails are filtered by an external antispam provider (they do an excellent job), and then forwarded to a box that that I collect from, rDNS doesn't work on then so that they can't get spam attacked!!!
Sound like time to change provider ......
This is crazy.
</rant> it is not a fix, do do it without proper notification has to be irresponsible to say the least.

Not have an rDNS will not stop them getting "spam attacked"
Not having an rDNS is against RFC1033 ( http://tools.ietf.org/html/rfc1033 ) which your spam providers should be following.
In short, your spam provider should have an rDNS entry for their delivering server.
Running a mail delivery server without an rDNS entry is irresponsible, to say the least.

I may have it wrong, can you check them then for me please , here is a header from an email earlier this week:
Received: from [217.72.243.41] (helo=uk.advascan.com)
  by pih-sunmxcore09.plus.net with esmtp (PlusNet MXCore v2.00) id 1Icorv-00027s-Is

Thanks

Do a Reverse DNS lookup at http://www.dnsstuff.com/tools/ptr.ch?ip=217.72.243.41 and you'll find the answer is:
217.72.243.41 PTR record: uk.advascan.com. [TTL 14400s] [A=217.72.243.40] *ERROR* A record for uk.advascan.com. does not point back to original.
That's probably why it doesn't work!

The server above should be fine. Whilst the forward and reverse DNS entries don't match, it does have rDNS configured:

Looks to me like it's sorted now. You still having the same problems?

Hi,
Are Plusnet mail servers refusing connections? I've received about 25% of my normal mail today. Mail sent to my own address has not been delivered and  mail which I know was sent by a Shan friend (Myanmar/Burma) is also missing. (Myanmar is partially connected to the outside world again.)
Thank you.

They definitely appear to be accepting connections and we're not aware of any issues:

C:\Users\Bobby>telnet mx.core.plus.net 25
220 mx.core.plus.net ESMTP Exim Sat, 06 Oct 2007 19:57:29 +0100

C:\Users\Bobby>telnet mx.last.plus.net 25
220 mx.core.plus.net ESMTP Exim Sat, 06 Oct 2007 19:59:00 +0100

Does mail sent to your address get bounced back to the sender? Is it mail that's being sent from a specific address that's not getting through? Have you checked your 'Spam' folder?

[#14]

Thanks for the prompt reply.
Mail is not bounced back as far as I can tell.
Various addresses appear to give problems.
I check my spam folder at times like this.... and I'm bound to say that your Spam filtering does a pretty good job. Only the odd false positive... which is why I've started using PlusNet for my mail once again. 
The tricky bit is that this problem appears to be intermittent.

[#15]

Yes, I know it's only 20 minutes, but it is a " PlusNet - Thank you for your question" email.
Header shows a delay - probably by EXIM:
