what is this sender option?

[devSajan]

here we have email and sender in options, email: 'name@example.org', sender: 'name@example.org'

if we are aws ses so do we need to add aws mail in the sender option or it will be the same as email like shown in the doc example?

Sender is for when you are contacting the mailbox of the recipient you need to provide a sender address when doing that in compliance with the SMTP protocol

https://github.com/mfbx9da4/deep-email-validator/blob/master/src/smtp/smtp.ts#L45

The default is simply name@example.org

https://github.com/mfbx9da4/deep-email-validator/blob/cefb37abc6e42d3a1551d38f9706d4ff538226e5/src/options/options.ts#L3

Probably you don't care about the sender option and it should work just fine.
