There is no built in criteria in Casper that will do this for you. But, you could build an Extension Attribute or 2 that would pull info on setup Mail accounts per user on the system and then you could use this for your Smart Group criteria.
I just put this script together. Not well tested, but give it a try.
#!/bin/bash
while read user; do
MailAccts=$(ls /Users/$user/Library/Mail/V2/ 2>/dev/null | egrep "IMAP|POP" | sed 's/^IMAP-//g;s/^POP-//g')
if [ ! -z "$MailAccts" ]; then
resultArray+=("$user: $MailAccts")
fi
done < <(ls /Users | grep -v "Shared")
if [[ "${resultArray[@]}" != "" ]]; then
echo "<result>$(printf '%s
' "${resultArray[@]}")</result>"
else
echo "<result>None</result>"
fi
It should hopefully pull the accounts that are set up per user and reports back. I'm specifically excluding Exchange accounts in this check, but that could be added as well if needed. Note that I only have an IMAP account set up on my Mac, so I can't check to see how some other accounts look once they've been set. But I think this should capture the most common types - IMAP and POP.
Note that I did not really research this much. There may be a plist file you can read with defaults or something that would get you the same info, though it would still be a unique plist per user account anyway.
