Hi guys,
I 've been brewing this shellscript, but I can't test it until next tuesday.
In the meantime I am too curious wether it will work or not, so I'd like to hear your comments.
Background:
I want to watch the user quota for mailboxes in various email-domains on a IMAP-server.
I have a list of directories in which the user mailboxes reside (domains.txt). The dirnames are named after the specific email-domain.
The users' mailbox quota is at 100 MB.
So if the quota will reach 100MB or more, it is written to a report for the mailserver admin.
And an email is written to the responsable person for the email-domain.
shell=bash
OS=Debian Linux
Thanks & regards, A.
