NTL ISP email problems

As you may have noticed, I had been having problems with my email service. (It's all working now, so I do not need offers of other providers.) When you send emails to me through this site, my web site hosting service receives the email, rewrites the envelope to point to the email address provided by my ISP, and sends the email on to my ISP, so I can collect it using POP. This way, I can change ISP as many times as I need, and you never need to know, because I can direct the email to my new ISP. The email address you use never needs to change.

This is perfectly normal, and is done by many email users. Aditionally, it means I can create as many email accounts as I need, and direct them to any recipient mailbox that I want. And if I decide to change my public email address, I can do that without ever having to change my ISP. I actually use several hosting services, and depending on how everything is set up at the time, your email may go through more than one of these. But eventually, the last host (tomsk.portland.co.uk) should send the email to the NTL email server (smtpin.ntlworld.com).

However, on 15th March 2005, NTL (my current ISP) started rejecting every email that my host tried to send to me. About 100 emails a day were being rejected, including emails sent by any of you. I tried testing one of these myself, and tomsk.portland.co.uk sent me this bounce:

Final-Recipient: rfc822; foo@ntlworld.com
Original-Recipient: rfc822; original@mydomain.co.uk
Action: failed
Status: 4.0.0
Diagnostic-Code: X-Postfix; host smtpin.ntlworld.com[212.250.162.8] said:
452 Message rejected (in reply to end of DATA command)

For those of you who are unfamiliar with bounce messages, this is tomsk.portland.co.uk saying that it tried to contact smtpin.ntlworld.com to send it the email. smtpin.ntlworld.com said that it would accept the email, but then when tomsk.portland.co.uk actually tried to send the email, smtpin.ntlworld.com rejected the email without giving any reason why.

What follows is a transcript of the emails sent between me and NTL, provided (almost) in full, with email addresses changed to protect the guilty.

I sent them this via their feedback form (no email address listed on site):

28th March 2005

[Loads of information reguarding the account, such as the address and
post code, the type of account, etc.]

Account is held in the name of [NAME REMOVED] - I do not have the account
number to hand because I am out of the country right now.
 
I use the NTL email address:
foo@ntlworld.com
and my wife uses
bar@ntlworld.com
 
Neither of these email addresses are given out directly, and instead we
use email aliases for *@mydomain.co.uk
 
Since 15th March, neither of us have received any email at all (except one
spurious email on 18th march). Normally I would expect to receive about
100 emails a day - about 90% of which is spam, but at the moment I am not
receiving the legitimate email either.
 
I have sent myself a test email which finally bounced after 5 days (nearly
a standard retry period). The bounce email was sent by my mydomain.co.uk
hosting service: portland.co.uk, saying that the NTL servers rejected the
email after the DATA stage. I would attach it so you could see all the
headers yourself, but the NTL site refuses to give me an email address
(potmaster@ntlworld.com maybe?) and insists that I use a web page form
that does not allow me to attach emails. The bounce message is included
below, with appropriate headers.
 
This sounds like an over-zealous spam filter. If it is, please disable it,
because it is trashing all my legitimate email, and I am perfectly capable
of filtering my own spam. If it is not, is it just that you have blocked
my email alias domain because it sends you too much email? (it's an email
alias domain, it is meant to do that)
 
Cheers

I got this response (fast enough):

From: cablemodem_support@ntlworld.com

Hi
Thanks for your recent e-mail
 
We currently don;t have any active spam filters on the servers so I
would suggest you contact mydomain.co.uk for more information
 
I am sure you can appreciate, some faults are very complex and in some
cases there too many variables involved for it to be practical to
resolve the problem via e-mail. On these occasions, our Technical
Support Callcentre is open 24 hours a day, 7 days a week to help you.
The number is  0845 650 0121 . Calls are charged at  a local rate
 
I hope this helps to answer your queries. Should you need further
assistance, please don't hesitate to contact me again.
 
Yours sincerely

Emma,
 
thanks for the reply.
 
> suggest you contact mydomain.co.uk for more information
 
I am the owner of mydomain.co.uk, and an (ex) email administrator, so I am
quite used to the headers I am seeing  in this bounce email. NTL's servers
are rejecting my emails, not mydomain.co.uk. Since you have no spam filters 
blocking it, there must be some other reason for your servers rejecting the
emails that my hosting service is attemting to pass on. If it is not spam
filtering, it may well be a manual filter for certain recipient addresses
(or aliases), sending servers, or message content.
 
Unfortunately, I am getting no more information than the bounce message
itself (where your servers do not say why they rejected it, they just
reject it), so I probably need to get in touch with the NTL email
administrators.
 Would you have a direct email address I can use to contact them?

I am currently in Norway for a few months, so a telephone is not such an
easy thing to use, as international phone calls get very expensive

This number does not work from Norway.
I have added the 0044 international prefix (00448456500121) as for other UK
numbers, but it appears that 0845 is a special number that is not
accessible from international lines.
 
Do you have a number that will work from Norway?

I got no response so I sent this (for the first time, I did not include the email comment history):

I already sent this but got no response, so I am trying a resend.

This problem is, as stated, a significant inconvenience, as I have now been
without email for about 3 weeks. So I really want to get this sorted as
soon as possible. But since I am going to be in Norway for nearly another 6 
months, I cannot use an internal UK number.
 
 
Thanks

Again, I got no response so I sent this direct to postmaster@nlworld.com (just guessing - since all email domains are required to have this account for contacting the email administrators):

07 April 2005
To: postmaster@ntlworld.com

Hi,
 
I have tried going through customer services, but they have only given me a
phone number that does not work, so I will try contacting postmaster
directly;
 
I am an NTL broadband customer, and I use NTL's POP service for my personal
email. Normally, I would get about 100 emails per day, of which about 90%
are spam, but have received only two emails since 15th March.
 
I do not give out my NTL email address directly (foo@ntlworld.com) and
instead I use an email alias domain which I own (*@mydomain.co.uk, hosted
by tomsk.portland.co.uk). Since 15th, NTL servers have been bouncing every
email that is sent via my alias. Unfortunately, the only message provided
in the bounce is this:
 
"host smtpin.ntlworld.com[212.250.162.8] said: 452 Message rejected (in
reply to end of DATA command)"
 
Without any reason as to why it was rejected, so I do not know what I am
supposed to do to stop you bouncing it. 
Have you specifically blocked my host or alias domain?
 
 
I am currently in Norway for 6 months, so I am unable to use the 0845
internal UK number.

Miraculously, my email immediately starts working again.

Finally I get this response to an email I sent 8 days earlier:

11 April 2005
From: cablemodem_support@ntlworld.com

Hi
 
Thank you for your recent e-mail.
 
Unfortunately, I do not have enough information from your e-mail to
diagnose the problems you have been experiencing or locate your
account. We need a clearer view of your computer's activities prior to
this problem occurring. Can you please email again with a few more
details about the problem. I will then be in a better position to help
you.
 
I need to know the following:
 
<<insert technical questions here: no more than 4 unless its
essential>>
[The fact that they left that line in the email speaks for itself]
 
Also, can I ask you to include either your NTL username/email address,
or your full postal code in all future emails. This will enable us to
keep an accurate account of any correspondence between us, and avoid
repetition of the same advice.
 
I hope the above answers your query, however, should you need further
assistance, please don't hesitate to contact us again.

I sent this (unimpressed) email:

11 April 2005
To: cablemodem_support@ntlworld.com

Jason,
 
> Can you please email again with a few more
> details about the problem.
 
The original email sent to you (I got replies from Emma) had full details,
including the bounce message showing that your servers were bouncing email.
 
Emma also sent me a number saying I would have to call to sort out the
problem. However, the number did not work from Norway, and my reply was a
simple question; to get a number that _would_ work from Norway, something
that you have also failed to provide me with.
 
Maybe it might be useful to reply using individual email addresses instead
of the generic cablemodem_support@ntlworld.com, that way, when I reply to
Emma, she might actually get my response, and know what I was talking
about, instead of you, who (through no fault of your own) know nothing of
the history of this incident.
 
Nonetheless, I have now bypassed your customer services, and gone directly
to your postmaster. The problem has been solved. It is unfortunate that
this is the course of action I have to take to get a simple problem solved, 
when all that was needed was either to forward the original email to your
postmaster, or to give me a simple telephone number. Surely it is not
_that_ hard to tell me your international phone number. You are, after all,
a telecom company.
 
> Also, can I ask you to include either your NTL username/email address,
> or your full postal code in all future emails.
 
I will do so for all future contact - although in this instance the problem
was purely related to your incoming SMTP servers, so all that was really
needed was to forward my original email on to your email postmasters. My 
original email contained all the details that they needed and did not need
any further information.

AAARGH! Not only are they incompetent, completely unable to use the 'Forward' button, unable to send a phone number that works in the country I am living in, unable to read a simple request, unable to work out that it is not their name at the top of the email. They are also incredibly insulting; "noresponse" and the same useless phone number. Again!

So I used their complaints form to send this:

Enter your comments here:
Your email servers were misconfigured and were blocking me from receiving
email. It was a simple problem, and could have been fixed in just a couple
of minutes. But the sheer incompetence of the NTL staff who replied to my
requests was completely astounding. I have kept a full log of the
conversations, so you can see for yourself what I mean.

I am not saying that NTL are a bad ISP. You can decide that for yourself. In fact their broadband is very reliable. And their technical people (once you get hold of them) really know their stuff. But as the email transcripts from this loss of email service shows, trying to get hold of their technical people can be very difficult when they are hidden behind "customer service". NTL, try learning from this incident. Some of your procedures are in desperate need of review.
