I can't quite figure this out. Has anyone ever encountered a problem whereby people using the webmail send emails that randomly appear to come from a totally different user on the system?
For example, abc@domain.com sends an email but it appears to come from xyz@domain.com instead! Also, when entering the settings, user abc@domain.com sees xyz@domain.com users settings.
This happens randomly, sometimes it will happen, sometimes it wont and the user that gets substituted changes randomly.
I'm aware that a proxy can cause this but the people in question aren't using a proxy. Any tips or pointers would be greatly appreciated. |
