回答1:
You need to put the libmysql.dll in the C:\Program Files (x86)\hMailServer\Bin\ directory. If you've installed WAMP, you can get a copy of this .dll from the C:\wamp\bin\mysql\mysql5.x.x\lib folder.
回答2:
if you have a 64bit MySql server installed, using hmailserver, you will have to search LibMySQL.dll and download 32bit file. be warned to avoid error.
回答3:
- Go to https://dev.mysql.com/downloads/connector/c/
- Download Windows (x86, 32-bit), ZIP Archive
- Extract the downloaded folder
- Copy the libmysql.dll file from (extracted folder)\mysql-connector-c-6.1.10-win32\lib\libmysql.dll into C:\Program Files (x86)\hMailServer\Bin
- Right click the libmysql.dll file and click Properties
- If there is an 'Unblock' checkbox down the bottom of the 'General' tab, check that and click OK
- Restart/continue with the hmailserver installation
