List of Mailboxes in WHM/cPanel

The well-known Plesk stores mailbox records in a mysql database. Meanwhile, you can get a list of mailboxes in WHM cPanel using the following script:

#!/bin/bash
for f in $(ls |grep -v "^\.\|virtfs\|lost+found\|cpeasyapache\|quota.user"); do
  f2=$(echo $f |sed 's/\/$//g');
  for box in $(ls "$f"/mail/ |grep -v "^\.\|new\|cur\|sent\|tmp" ); do
    m=$(ls -l /home/"$f"/mail/"$box"/ |awk '{print $9}' |grep -v "^\." |sed '/^$/d');
   	if [ "$m" != "" ];then
     	for m2 in $m;
     	do
       	echo "$m2"@"$box"
     	done;
   	fi
   done;
done;
