Email Notifications Stopped

[judan]

Hello. MantisBT users have stopped receiving email notifications for a while now.
The notification setting: $g_enable_email_notification = ON; is in the config_inc.php file. Settings weren't changed so i'm not sure why notifications have stopped.

Here is a snippet of the logs when '$g_log_level = LOG_EMAIL;' is enabled:

2014-05-30 10:40 ART mail Issue = 0000060, Type = bugnote, Msg = 'email_notification_title_for_action_bugnote_submitted', User = @U12, Email = 'user1@banksdih.com'.

The provided information is not sufficient to provide any help in resolving the issue.
All I can say at the moment that MantisBT tries to send 502 mails and all went well in MantisBT.

You should provide at least your email configuration (do you use SMTP, mail or sendmail?)
Did you check web server and mail logs? Are there any warnings or errors in it?

Are you able to sent emails from same system by using other applications?

BTW, having a look at your settings (especially the green ones)
Do you really want to sent that much emails?
e.g. administrators and managers get email whenever any user adds a note to any issue.
Maybe this is also the reason for your problem as your emails might get rejected as some kind of spam.

Are you referring to the Email configuration in the config_inc.php file for mantis? If so then the only email configuration i have for mantis is:

$g_enable_email_notification = ON;

This is all i had and it was working.

[atrol]

$g_enable_email_notification = ON;

As a side note: This is the default setting. You don't need to set it again in config_inc.php.

You didn't respond to my other questions.
