Reset hMail Administrator Password
If for any reason you need to reset the hMail administrator password, edit the following file: C:\Program Files (x86)\hMailServer\Bin\hMailServer.ini
In the hMailServer.ini in section
[Security]
AdministratorPassword=xxxxxxxxxxxxxxxxxxxxxxxxxxxx
This is NOT a Blowfish or SHA Algorithm. It is really an encrypted MD5 Hash.
To reset your Administrator password do the following:
1) Stop the hMailServer Service
2) Goto your hMailServer Program folder (for example: c:\Program Files (x86)\bin\
3) Copy or make a Backup of your original hMailServer.ini file
4) Insert a new MD5 Hash and replace the old password with a new password.
This should look like this:
AdministratorPassword=cc03e747a6afbbcbf8be7668acfebee5
5) Open hMailAdmin and click connect, this will start the hMailServer and provide the password box
Your new Admin login password is: letmein
You can generate a MD5 Hash from some other password anytime for example at:
