updating with yum

I installed a few month ago a postfix on a fedora core 5 box, I followed this manual:

fedora_virtual_postfix_mysql_quota_courier

today I was checking my server and when I checked for updates

Code:

yum check-update

I noticed the following updates were listed:

If I update this modules specially ldap, courier* will my postfix installation still work without a problem? will I need to reconfigure courier-mysql? and all the other files?

Hope you can give a hand on this.

Regards,

 

I do not now if you have to reconfigure anything in your special case.
But I noticed in all updates I have done with yum in the past, that if yum or the updated package changes any configfile, that it notices you about that and the old is saved as *.rmpsave (or sth. similar), so that you can check with diff or anything else if something critical has been changed.

 

Thanks Ben,

Then I´ll try to update my sistem hopefully it won't cause any problem with my postfix instalation.
