Hi everybody,

Happy new year.

This is the fifth year I have been using these newsgroups, and all of you
have helped so much and I am very grateful, (humbled even).

I only wish my bank and garage was so obliging!!! (two chances of that -
slim and fat!!).

Anyway, to business.

Could you possible let me know what this error message means.

Thus:- ""Remote MTA squall.mail.adnap.net.au: SMTP diagnostic: 550 Reverse
DNS is not setup correctly for this host.""

Many thanks

Steve

I'm going to guess that you sent a message to someone at adnap.net.au
and it bounced back to you with that error message in the body.

It means that the adnap.net.au mail server (squall.mail.adnap.net.au)
attempted to verify that mail was coming from the mail server that said
it was sending it by looking up the IP address of the sending server and
comparing via Domain Name Service (DNS) look up. It's a way to catch
spam from servers that claim to be a legitimate service.

This typically means that you ISP's mail server is not correctly set up
to allow reverse DNS.

It could also be a temporary glitch in the reverse DNS lookup and if you
resend the message, it will work next time.

Hi,

First in reply to bear, here is what I believe is the whole message:-

"These recipients of your message have been processed by the mail server:
"realnameremoved"@adam.com.au; Failed; 5.1.1 (bad destination mailbox
address)

Remote MTA smx1.mail.adnap.net.au: SMTP diagnostic: 550 Reverse DNS is not
setup correctly for this host."

Please let me know if there is any more info you need.

Michael, what a guess!!, are you also a medium, (or maybe a large).

What I forgot to mention, is that it is a friend who is having the problems,
he often sends e-mails to multiple recipients of which I am one.

The notreal@adam.com.au address has been current for at least a year or
more, The rest of us are able to send to this address ok, my mother sends
regularly with no prob's.

Since two or three weeks ago our friend has had the notreal@adam.com.au
bounced back whilst the rest of the recipients get through ok.

He says he has received e-mails from notreal@adam.com.au (but not in return
to his e-mails) , but cannot send to them.

Many thanks.

Steve

The 2 error messages seem to be talking about different errors. Are
they appearing in the same bounced message? If he i sending to multiple
people, then there could be 2 recipients that he is having trouble
sending to.

The first one

"These recipients of your message have been processed by the mail
server:
"realnameremoved"@adam.com.au; Failed; 5.1.1 (bad destination mailbox
address)

would indicate that adam.com.au there is no one with the e-mail address
of "realnameremoved". In other words, that the sender has the wrong
e-mail address for the recipient. Possibly due to a type in the e-mail
address, perhaps in his address book.

The second error message

Remote MTA smx1.mail.adnap.net.au: SMTP diagnostic: 550 Reverse DNS is
not
setup correctly for this host.

indicates that the recipient's mail server doesn't like the sender's
mail server becuase of the reverse DNS is not set up by the sender's
mail server. In that case, the sender needs to contact his ISP
regarding the issue.
