I have been trying to use the Polarhome webmail interface to reply to emails and send new emails during the past couple of days. It always fails, no matter which machine I am logged into, whether I use my shell account login or a non-shell account login.
In the webmail client page I enter my reply or my new email, enter a Subject line, check the To address for validity, and press "Send Message". It always replies:
ERROR:
ERROR sending message to test@example.com
(Bogus email address substituted in example).
The From address, entered automatically, is always correct.
Am I just unlucky, or is this currently a known problem with Polarhome webmail?
Is this related to Polarhome's disabling of basic socket functions, etc, in PHP and the like to prevent abuses?
I can send emails from my shell account (on debian), no problem, so the underlying mail delivery system seems to be working happily.
