Accessing other user inbox


I want to start by expressing my thanks for this great piece of software. It is very easy to use and has worked without problems.

I only have one question: is it possible to gain access to a user’s mailbox without having to change the account password? I searched high and low for a solution but to no avail so far.

Alternatively, is there a way to implement a mail forwarding so that when the respective user sends or receives e-mail, it will be forwarded to another e-mail address?

Thank you in advance for your assistance in these matters!

Best regards,

Follow the above instructions to create your master user & password file.

I added the conf stuff (“auth_master_user_sepa…”) to this file:


Then in order to integrate it easily into the web on roundcube use this older but functioning plugin:

I have tried it and it works well for my needs. Make sure the password is super hard and long and does not get out!
