Postfix / sendmail again

Sorry for my seccond topic about postfix.
I read many problems with postfix and ispconfig, postfix is easy to configure i know, but i will change to sendmail.
I use very large mailinglists and i can´t run it under postfix.
Maby can someone write how to migrate postfix/maildir to sendmail/mbox step by step.
My software is CentOS / ISPConfig Version: 2.2.3

Thanks, Herbrert
