But in recovery instruction I read this.
If your account was hacked
Email
recoveries...@bitcointalk.org,
ideally from the account's email address. Include your username and a brief description of the details of how/when the account was hacked. A signature will likely be required (see below).
Can he recover his account just with the signed message or email address is mandatory ?

Ideally =/= necessarily.
AFAIK they check a lot of things like IP addresses and activity. Not only a signed message and if the email matches.
