Title: Unable to send mails, rejected and not in mail queue
Post by: idc on July 20, 2016, 10:01:28 AM

Hi
All of a sudden I cannot send any emails with mail client.
Error is
Server Error: 450
Server Response: 450 4.7.1 Client host rejected: cannot find your hostname, [my isp number]

The message does not appear on mail quueue in web panel

The only change that I know of is my isp number is dynamic; and has changed today after reboot of router.

I can receive emails without issue.

ANy ideas how to fix?

Hi
I have checked mail logs and nothing abnormal is showing up.

I can send email with roundcube without issue, but I cannot send anything with mail client.
