Email - Field "From": Possible security issues -


i have question concerning security of from field find in emails.

here's use case: want allow customers send emails third parties through java application. from address same , email managed application. want allow customers set custom name in from field. example:

from: john doe <noreply@myapp.com>

so in example, noreply@myapp.com 1 of application email john doe value submitted customer.

i'd know possible security issues?

just make sure validate, sanitize , escape user input.

if app allow customers control body , recipient aware can send mails looks own mail. recipient not check address, @ name , name can 'ymansour'
