Re: [Exim] Exim_MySQL problem

I still have a problem with Exim and MySQL. My config works on other systems
very well (for example on FreBSD), but on RedHat Linux7.2
I have a problem when Exim tries to connect to MySQL database. This is my
config file:

When I go to test Exim by telnet I get this error message:

....but when I connect to MySQL "manually":

                > mysql -u exim -peximpass

...I have no problem !!!! The connection is passed !!!
Where is a problem ? What can I do to fix it ? By the way, without MySQL
"part" in configuration file, Exim works well !!!
