Warning Issues: Unable to send mails and notify subscribers

Postby saurabh_kudesia » Tue Apr 04, 2006 11:40 pm


I am getting following message while posting emails to the subscribers. The mail system was working fine untill recently. Pl. help me as I am unable to send notifications to users.

This problem exists even when sending message to any user. I am using OJS v 2.0

Hi Saurabh,

This is probably a PHP upgrade issue; see http://bugs.php.net/bug.php?id=17322, for example. For a potential work-around, configure OJS to use its own SMTP client in config.inc.php (see the [email] section).
