Hi all!

Some times I got the following failure:

--
Jul 17 16:44:51 myserver postfix/smtpd[22200]: NOQUEUE: reject: RCPT from xxxxxxx .deli.com[11.222.33.4444]: 450 4.1.1 <OFFICE@our-domain.com>: Recipient address rejected: unverified address: Address verification in progress; from=<the.customer@deli.com> to=<OFFICE@our-domain.com> proto=ESMTP helo=<xxxxxxx .deli.com>
--

The address *OFFICE@our-domain.com* doesn´t match with *office@our-domain.com*

How can I solve this issue?

Thanks, mbsouth

Re: Address verification (lower/upper case)

Obviously, recipient server 'xxxx.deli.com' has some spam policy and it says "Address verification in progress".
It's better to contact its mail administrator to understand how it works and avoid this issue.
