Hello,
my omv 4.1.26-1 running fine but...
i prefer to use postfixadmin -> http://postfixadmin.sourceforge.net for postfix.
I agree that omv is not and will never be a full MTA config system - so it shoud be possible to (1) disable the postfix config option in omv and using simple mail command, independend of the MTA ... postfix/exim/sendmail/...
The additional and optional choice may be, (2) omv using the "postconf" command to manage/modify postfix configs as designed by postfix
or (3) do config postfix in a optional Step selected by Hand or even ask if it shoud do this...
But not write postfix configs all Time like a Bulldozer!
IMHO sending by an MTA using mail command like mdadm or smartd do... and configuring an MTA by writing MTA blind configs ... are 2 totaly different and independend Tasks. Shure, both Steps are nessesary to send a mail in a simple setup but there is no Reason to bundle them in this inflexible way.
Thank you
best regards
