Question

Problem Statement:

I'm getting TO email in FROM email which of course will not be verified in Amazon SES in POST password/email.

---

Description:

Let to@example2.com will ask for Password Reset Link via email. Generally from@example1.com will send password reset link. However, In my case to@example2.com is trying to send password reset link to itself.

In Amazon SES we need to verify email to send mail through SES service. So I've verified from@example1.com.

Note: Both domain are different example1.com and example2.com. example1.com is setup on Amazon SES.

Exception:

Swift_TransportException (554)

Expected response code 250 but got code "554", with message "554 Message rejected: Email address is not verified. The following identities failed the check in region REGION: to@example2.com "

It seems to me like your AWS mailing service or Laravel is not correctly setup

https://aws.amazon.com/premiumsupport/knowledge-center/ses-554-400-message-rejected-error/

You could try using mailtrap.io out of the box to test stuff.

That kind exception usually raises when the Server that's supposed to send the e-mail is rejecting it. Usually the case for SMTP or AWS SES. There is also a possibility that you're trying to send through an outlook account through SMTP and security policies won't let you send the message.

However if I got this right you want to send emails as if people sent them theirselves. That won't be possible because you don't have the ability to verify all emails. *@*

As a solution you can use reply-to option, or no-reply as the sender if you don't want the user to be able to reply.

If you are not trying to send mail as to@, but instead from@ make sure the MAIL_FROM_EMAIL is correctly set in env.

Emails should not be sent unencrypted

Email ports to use:

Protocol    Security Setting    Port Number(s)
SMTP (sending mail)     Encrypted - TLS/STARTTLS    465
SMTP (sending mail)     Encrypted - SSL             465
SMTP (sending mail)     Unencrypted                 25* (or 26)

POP3 (receiving mail)   Encrypted - TLS             995
POP3 (receiving mail)   Encrypted - SSL             995
POP3 (receiving mail)   Unencrypted                 110
IMAP (receiving mail)   Encrypted - TLS             993
IMAP (receiving mail)   Encrypted - SSL             993
IMAP (receiving mail)   Unencrypted                 143
