Hi List
Email is sent to multiple recipients.
When for whatever reason, recipients have incompatible settings (one
wants spam to be rejected during SMTP Handshake, another one wants
spam to be tagged and delivered to his inbox as example)..
...during the 'RCTP TO' phase, we don't yet know what

Hi
Thank you for the feedback.
So I wonder if others might have found a clever solution to that
problem.
Goal 1: Do NOT send a delayed bounce. (aka backscatter)
Goal 2: Never have an email 'disappear' in the system.
Goal 3: Respect Recipient's anti-spam settings.
Consider an email sent to two

If both MTAs support PRDR you can selectively reject after DATA.
Few do.
Otherwise, you're doing the best you can. Train
No matter what, even if you use a sophisticated MTA that can identify
separate spam rules for each recipient, typically not all spam checks
can occur until after the DATA stage. If you accept one for delivery,
you have to accept all, however since you don't want to create

Logging alone is not good enough. Emails disappearing without a trace
(for the recipient and sender) are always bad.
Spam Mails usually are delivered to single recipients. So the

I’m sorry to hear about your father. Feel free to send me his address off-list

For us, for users in the same domain, we basically "make due" with a combo,
and I think our docs point this out.
We also have the problem of multiple domains, however, and we don't want to
try and combine rules across domains... so we reject with 451 4.3.0
As you say, many MTAs will do an ok job
Hi John,
We don't send as much mail as the ESPs you've mentioned but I'd be happy to
make sure your father's address is no longer emailed via Campaign Monitor
(if ever). Feel free to email me directly with his address.

John,
I went through the same thing after my mom passed... no fun for sure, probably
even more complicated that he has a say(Thankfully)!
Depending on the carrier, you could perhaps leverage alias functionality as I
did. I changed all of her transactional contacts to googlemail.com and created

Hello Benoît
How are your customers expressing that they want the message to be
"rejected"? And who sets the rule conditions?
I was thinking that maybe the best way to design such system would be to
convert the "reject" option to "delete this message automatically", but
actually saving them in a

Shoot me his address and I'll get it removed from all CTCT lists.

And, they are doing their own mailing, from mail-target.com, so I can't even
complain to their ESP.
Anybody have a contact?
Thanks in advance!

My elderly father is no longer able to handle his own e-mail, so I'm
doing it. He gets a mountain of junk mail, from every organization
with which he has ever done business, from the local community theater
to auto parts.

as far as I know you can ask Mailchimp's abuse department

Does the mailbox provider/MTA support restricting senders to those already
in the address book? I've seen this work very well in a broadly similar
scenario.
Or, there's always CR... ;)

I would much rather explain why an extra message was put into the spam
folder than explain why we didn't deliver a message.
