After making the first contact with their postmaster team, I receive a 
response requesting to send an example to a special mailbox. I comply 
immediately, even if off the clock. After that, I don't get a 
response.


I've found BT's postmaster team to be very responsive in the past.  I 
invariably get replies from actual humans.


Perhaps many/most of those humans were on holiday last week and they're 
now catching up with a backlog?

I am sometimes asked for our opinion on which "address verification" service
we might recommend when providing our deliverability consulting service,
usually as part of launching a new customer for our software.

If they are also hosted on our network (our "cloud" solution) I point out
that, if they intend to upload and send to a washed list, we will know about
it almost immediately, and will notify them that they have been terminated for
AUP violations.

For others ("on prem" solution), depending on my mood and the apparent
character of the customer (total babe-in-the-woods, ambitious newbie, seasoned
spammer) I tend to ask how much money they have to waste.  You are paying
someone else to burn down their IP range determining whether some finite
quantity of spamtrap addresses are valid at RCPT TO time.  One poor sod, who
gave up after a major network provider toasted their account due to Spamhaus,
SpamCop, SORBS, and other issues, noted in sorrow that he had spent close to
$5K getting to that point.  

Perhaps he can take up chinchilla ranching.

Our team is discussing this internally, and curious about others position on 
addressing list washing services.. Some are better than others of course, 
identifying themselves correctly..



But then there are those on Digital Ocean or AWS that use throwaway domains, or 
no clear identifiers..



While the idea of 'validating' an email address seems like a logical thing to 
do, some of the list washing services appear to be just used to wash old lists, 
or email address harvesting..



What is the position of the industry on these issues..



Eg..

 I think this is a test address to verify if the server supports valid user

If Validity (new owner of Return Path) hasn't retired this address,
then it's probably the best place to report this:
Return Path 

They manage the FBL in question.

(hit send on the wrong email - to continue...)

fbl.senderscore.net is what they've used in the past so perhaps it's a user
on-boarding issue.

However, I wouldn't have any expectation that emails sent to RFC2142 type
addresses would pass spam filter tests. Was it a valid RBL report?

[mailop] BT Internet postmaster contact

[Mawutor Amesawu via mailop]

Hi there!

I've opened several cases with them concerning a false positive spam issue
for a high profile client. A third of their messages are being marked as
spam with the following error:

"Your message looks like SPAM or has been reported as SPAM"

The messages are transactional in nature from a high profile retailer.

After making the first contact with their postmaster team, I receive a
response requesting to send an example to a special mailbox. I comply
immediately, even if off the clock. After that, I don't get a response.

Any help would be appreciated.
