I recently took over a Mantis Bug Tracker system version 1.2.0 (Schema182) and found one issue with "Lost your password" email notification.
All other notifications such as when creating a new ticket, sending a reminder and so on work good but when I select "Lost your password" at a logon page and type in the ID and registered email address then "Submit", I get no email.
The SMTP server is our internal one and the working notificaitons are all being delivered through that. I just in case restarted the SMTP server but didn't solve the issue.
I truly appreciate if anyone knows where to look into?
