Error sending mail with qmail

[Stuart Whittaker]

I have a client who sends mail via authenicated SMTP on my Linux system with Plesk 12.0.18 Update #78.

The mail agent is qmail.

He is sending and receiving mail quite happily except when he sends to one email address in particular. The message bounces everytime with the following message:


Hi. This is the qmail-send program at ***name of server***.
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.

<[email protected]>:

Connected to xxx.xxx.xxx.xxx but sender was rejected.

Remote host said: 550-Requested action not taken: mailbox unavailable

550 invalid DNS MX or A/AAAA resource record

I've attempted to do the same thing from the linux command line using my clients credentials and this is the extract from the mail log:

Is anyone able to shed any light on this?

Thanks in anticipation

This might be due to a unpatched qmail install not handling DNS queries correctly (we moved off qmail years ago but reading around suggests its still not patched in most upstream packages of qmail)

Switching to Postfix or applying the patch to allow for the larger ANY DNS queries would rule this out as a cause.
