address rejected: unverified address: Address verification in progress

Tait Grove
A handful of my email users are getting an error message from external
servers mailing to our servers. This error occurs when you change the letter
case in the email address. Example, if you send from Yahoo! to my server
using the address ‘[hidden email]’ the email will go through, but if you
email from Yahoo! to my email server using the same address with case
changes ‘[hidden email]’ you get a bounce back message stating “address
rejected: unverified address: Address verification in progress”. What causes
this error in these cases?

I attached a copy of the bounce back below.

Hi. This is the qmail-send program at yahoo.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<: [hidden email] >:
38.119.86.21 does not like recipient.
Remote host said: 450 4.1.1 <: [hidden email] >: Recipient address
rejected: unverified address: Address verification in progress
Giving up on 38.119.86.21.
I'm not going to try again; this message has been in the queue too long.

You have configured Postfix with reject_unverified_recipient.

Look in your logfile with

    $ grep "[hidden email]" /var/log/maillog | grep deliverable

and see what reason is logged.

The suggested grep returned nothing. So I ran this....


$ cat /var/log/maillog  | grep "[hidden email]"

And I got the following log results:

Aug 20 15:49:02 post-app2 postfix/smtpd[23676]: NOQUEUE: reject: RCPT from
ug-out-1314.google.com[66.249.92.174]: 450 4.1.1 <[hidden email]>:

Looks like you have 'sender address verification' enabled.

I'm not sure many people do this anymore...

What is the result of:

$ grep [hidden email] /var/log/maillog | grep deliverable
