Change of default message_size_limit

[PeterPtzn]

Hello,

how can i change the Plesk default postfix message_size_limit of 10000Kb permanently? After some microupdates my custom value of 51200 Kb was overwritten with the for me unusable default.

Thank you

What about

postconf -e 'message_size_limit = <necessary_value>'

?
