Perhaps the DBD::mysql perl module hasn't been fully installed,
or perhaps the capitalisation of 'mysql' isn't right.

Personally, if an iRedMail installation has so many unexpected error/issues, i prefer to re-install server os then re-install iRedMail to get a working one.
I reinstall mysql and iredmail but it has still error and also i can't reinstall debian again.
Sorry, I don't know what these errors mean.
Thanks for your help.
