Smart Group to identify Mail.app users

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.

Give this a try..

#!/bin/bash

# Name    : show-MailEmailAccounts.sh
# Author  : Nick Smith
# Date    : 20150803
# Purpose : Query /Users//Library/Mail/V2/MailData/Accounts.plist for active email accounts.

# Variables
currentUser=`ls -l /dev/console | cut -d " " -f 4`

# Begin script
theResult=$(defaults read /Users/$currentUser/Library/Mail/V2/MailData/Accounts.plist DeliveryAccounts | grep "CanonicalEmailAddress" | awk '{print $3}' | sed 's/[";]//g')


/usr/bin/printf "
$theResult"

@Snickasaurus Ah, see I knew there was some plist somewhere with that info.
Unfortunately, the script you posted doesn't actually produce a result on my Mac. I can see the Accounts.plist "DeliveryAccounts" has data in the array, but there is no "CanonicalEmailAddress" entry in it, so doing a grep for that doesn't yield a result. And I have a Gmail account set up within Mail.app, so its there for sure.

I don't know if it has something to do with a different version of Mail.app. I'm trying this on 10.9.5. Maybe that only works on 10.10.x?

@mm2270

Must be the OS difference then.. (OS 10.10.4 | Mail 8.2)

@tharr00 Give me a list of client versions in your environment so I can change the script up a bit.

Clients are 10.9.5 to 10.10.4 Thank you1

@tharr00

I will finish the script + testing tonight. Work swamped me this wekk.

has anyone been successful with this?
