Picture a mail store for virtual users.

After further research, I've come to the conclusion that this isn't possible; it's a form of file giveaway (because the postfix user would need to create files owned by backup). Looks like the backup program will simply have to run with group access to the mailstore, and thus be depended on to not change anything.

Is there any way to send a custom e-mail to custom recipients if any user tries to login or login to my system (RHEL6.7) ??

There are multiple ways to achieve what you are looking for. I will list out two ways to do it.

You may use procmail's locking to make multiple instances execute one instance of the perl script at given time. See man procmailrc and man procmailex
