i'm involved in product development, user register company. once becomes user of our product, need send announcements,newsletters etc. users on behalf company.

for purpose company email , password, need validate email valid , he's given correct password email id or not. i'am thinking 2 methods validate email , password,

  • send test mail smtp authetication
  • try open inbox.

i feel first 1 better later. because if user given wrong passwords, there chances considered attack.

any 1 can tell me there better way validate given email password.
