Proper way to implement postfix changes?

[adminsmc]

Being new to zimbra and postfix in general I've found myself having
to make changes to postfix settings for various and sundry items.
Adding in support for mailman, ensuring masquerading when using the
postfix submission channel are a couple of examples.
In order to make the first change I had to edit -
/opt/zimbra/conf/localconfig.xml
file to add in the "hash" entries for mailman's aliases files.
In the second change, I had to edit not only the localconfig.xml
file but also add an entry for the masquerade entry in zmmta.cf.
Are these the proper places to make such changes? Should I be
doing them differently? Will they survive an upgrade?
Just checking myself,
Thanks,
Doug

Hi Doug,

Try modify all the settings using "postconf -e" command.

After execute :

zmmtactl stop

and

zmmtactl start

this will make that the settings are write in the "main.cf"

Your English is great! This is exactly what I was looking for. Thank you.

So, just to get this straight: if I make changes to postfix using postconf -e, the changes will survive an upgrade?? This is contrary to what I thought I had read on the forums.
