I find the best solution to track the mail sent by us. i think it works
I forgot the Admin Password . when i try to get the password with the forgot option the mail is not received .but i know vbulletin save the password as MD5.
I give the MD5 for password even though it is not logged me. After a long time i found that they store the password as MD5 with the salt value
then i update the DB with the following Quert to set the new password as password for my admin login
set password = MD5(concat(MD5(‘password’), user.salt))
WHERE userid = 1
now it works fine for ME. i think it may be help you enjoy the Day 🙂
