mail / postfix problems.

Howdy,
I think I need to reinstall postfix, or reconfigure it but don't want to damage anything omv so wondering if there's an omv way to fix it.

I'm setting up a cron job to mail me when a disk fails in my raid ( lsi add in card, not managed in omv ), but having issues with using postfix to mail.

so i ran chckconfig which told me this
chkconfig postfix on
insserv: warning: current start runlevel(s) (empty) of script `postfix' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `postfix' overrides LSB defaults (0 1 6).
insserv: warning: current start runlevel(s) (empty) of script `postfix' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `postfix' overrides LSB defaults (0 1 6).

and there's no S* scripts for postfix in /etc/rc*, but lots of kill scripts.

should I apt-get remove then apt-get install postfix? not terribly familiar with debian package management but if so, plan on walking through this page https://wiki.debian.org/Postfi…iguring_Postfix_on_Debian

thanks for any advice.

partially answering this myself,

not necessary to do apt-get install postfix ( unsure if it would harm things still ).
proper way is go to omv web interface -> notifcations, fill that out and enable it. this adds the start scripts to rc*.d/ and probably other stuff as well.

didn't notice it in a guide yet, so for google I think either port works 587, ssl/tsl enabled, smtp.gmail.com then have to 'enable less secure apps' for your google account. that enable less secure apps makes it seem like i've messed up somehow though ( https://www.google.com/settings/security/lesssecureapps )

edit: adding that, since mozilla thunderbird also has to 'enable less secure apps' it can't be too bad and not worth figuring out how to set up google oath with a mailserver on debian.
