Email Servers On Spamcop blacklist
 

Hi

Just to let you know that some (not all) of NTL's email servers are on spamcops blacklist. So a % (somebody like to hazard a guess, ive been told maybe above 50%) of your email will never be delivered to its recipent (unless there on the NTL network) are ntl going to get this sorted.

Doesn't surprise me. Spam seems to be a long way down NTL's 'things to be the least bit bothered about' list. The amount of spam I get is ridiculous and it's not just directed at me. I see dozens of other ntlworld.com email addresses in the 'to' box. A lot of these spam emails are faked to look like they come from NTL emails so it's not surprising that the servers are going to start showing up on anti-spam listings.

It's hardly surprising - ntl's mail servers are some of the busiest in the UK.

However, they don't accept smtp connections from IP ranges *outside* their own network blocks, (i.e aren't open relays), and employ a spam harvesting algorithm to stop customers using dictionary attacks.

quoting from the Spamcop website: "This blocking list is somewhat experimental. This system and most other spam-filtering systems should not be used in a production environment where legitimate email must be delivered."

"The description of the algorithm used for deciding whether to block a host may be out of date, and is subject to change without notice.There is no warranty associated with using this system. It is provided as is."

It appears that mta08-svc.ntlworld.com has been placed on the blacklist due to the amount of email it sends. It's a mail server for one of the UK's largest ISPs, it always sends a huge volume of emails a day.

If you find your emails being bounced/blocked I'd recommend talking with the admins of the receiving ISP.

Who's been a naughty boy then?
This is a might inconvenient - will have to resort to old dog-and-bone now!

Re: Email Servers On Spamcop blacklist
 

I've also had legitimate mails blocked because of Spamcop blacklisting though interestingly one address is mainly accepted, sometimes rejected. How does that work then?!

Re: Email Servers On Spamcop blacklist
 

not any more ;)

Re: Email Servers On Spamcop blacklist
 

Many automated lists expire blocks after some time, it saves having to administer removals.

Some do only clear it on request, and some (personal, not recommended for production use) make highly opinionate judgements on large address blocks and whole ISP's (actually, for personal use, blocking the entire APNIC administered address range and the entire 24.x.x.x US cable ISP range would nuke 99% of spam, though possibly some wanted stuff too).

I've had a few messages from ntl users today that Mailwasher shows as blacklisted by spamcop.

Re: Email Servers On Spamcop blacklist
 

yup the mail servers have been blacklisted by spamcop again :rolleyes:

This is having a serious effect on my emails. Is there no one able to sort this out?

Oh hell, here we go, better get the dust off Bertie the carrier pidgeon.

Re: Email Servers On Spamcop blacklist
 

Well done someone!

Now can we shoot the customer who's causing all this grief? :D

Re: Email Servers On Spamcop blacklist
 

If there are any spamtraps (or do they mean user reports) on the NTL network, it seems that an innocent "intermediate" mailhost is being tagged...

The source IP does not tally:
69.40.140.63 = h63.140.40.69.ip.alltel.net (Proxy/Trojan according to CBL - abuseat.org )

Munged my email, and every ".com", to avoid giving spam harvesters targets that are reachable, if not valid

Re: Email Servers On Spamcop blacklist
 

As anyone who has read any of my other posts regarding anything vaguely technical will know, I'm a bit thick in this area. So can anyone explain the mail failure message from the NTL postmaster below, preferably in words of on syllable! Does Spamcop have a problem with NTL or the recipent, telegraph.co.uk?!

Cheers,

Andy

Spamcop has the problem with ntl-> details from spamcops site:

Re: Email Servers On Spamcop blacklist
 

Cheers Monkey,

I've contacted Spamcop to register dissatisfaction. Isn't there something NTL could do about this, like to take legal action. Spamcop is interfering with the operations of a legitimate business.... and hacking me off!

Re: Email Servers On Spamcop blacklist
 

Wahey! Success! OK, it might be short lived, but this message (plus the irate one I sent to prompt it) from Spamcop.....

The problem with the new NTL servers has been resolved. Your mail should
go through OK now.

Nice.

Spamcop, not a bad bunch of folks, well intentioned, and they will admit that their current blocking script should not be used as an absolute benchmark for preventing spam.
