XF 1.2 Zend_Mail_Transport_Exception

[Magic]

Hi folks, i seem to be getting errors in the server logs all similar to below.

I am however still getting email alerts from conversations, and users have been signing up following the email confirmation links.

Can anyone throw some pointers on where i could look to troubleshoot this?

Thanks

What version are you running specifically? If you're not running the latest beta, make sure you upgrade.

Otherwise, this is really just a generic mail error. Your server mail log may have more details.

Hi Mike, Im using the lates beta, 1.2.0 Beta 3

I will investigate further, and thanks for the reply. It doesnt appear to be affecting anything, so all is good
