On my Andriod tablet I wanted to email a document (pdf) to myself so I could pick it up off my laptop and print it... but the message kept getting bounced with a message stating:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
[email protected]
SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mx6.freeola.com [109.71.173.47]: 550 Sender address has been blacklisted
Some excellent responses reading through the logic.
Personally I'd rather stuff etiquette and not alert anyone I'd blacklisted to the fact that there is a live address at the end of their spam. If I was a spammer I'd get a list of te blacklist rejections parse through them and send out more spam under a different guise.
If anyone I knew got the blacklist message then they'd know where I was to sort it out.
If someone sends mail to a non-existent e-mail address at the server it should just 'fail' and issue a DENY command to the connection SMTP server.
The blacklisted response should be fairly quick and this will need to be looked into. Ideally checks should be done in an order a bit like this:
Address exists > address not blacklisted > address not spam > deliver to mailbox. The first 2 checks are very quick and not very processor intensive, spam and virus checking is what slows things down.
I have just tested EmailPro by blacklisting an external address and then sending from it and immediately got
550 Sender address has been blacklisted
. Its seems (for me) that failures for standard email are instant but emailpro is around 30mins as I've now had a failure for that.
Shame, as I liked Bob's previous logic regarding dictionary attacks.
Re. Blacklisting.
I'm glad JTD picked this up as I didn't realise it was working like this.

As this is more designed to prevent spam messages, then prevent contact from someone that you just don't want to speak to, the blacklisted response is used.
With regards to not sending a response, I've passed a request on to our systems team to see if a separate list could be implemented where emails from addresses would be accepted, then deleted, or moved to another folder, with no reject code sent.

host mx2.freeola.net [78.33.48.243]: 550 5.7.1 <[email protected]>:
Recipient address rejected: Unknown user
This should really confirm that the reject codes given are the same on both services.
My test was from:
Standard email > EmailPro and
Standard email > Standard email
I've just tried sending from an EmailPro account and that does produce the error. So it also depends on which service the sending account is on.
Perhaps you could find out from the team that looks after Email how things should be behaving? Especially the 'blacklisted' response?
Thanks,

EDIT:
I was testing/writing when you posted there.
As JTD picked up on - it's the 'blacklisted' response that needs to be stopped.
The smtp.freeola.net mail server does not send bounces if a message could not be passed on as far as I am aware. This is to do with the sending server, rather then the receiving server.
