How to send a mail from non existing mail? Example: [email protected] using Spring Mail Sender Configuration. A mail doesn't exists so that reply to email address should fail.

Solution with java mail also preferred.

I tried with this too. It is not working with spring framework. (Unknown Sender) when sending email with pdf attachment created in iText from java application

[email protected]

If you're not using SMTP authentication then it doesn't matter whether the email exists or not.

You can send email from addresses that doesn't exist without using SMTP authentication but that's usually a bad practice because such email's are usually evaluated as spam by most of the spam filters.

See this answer for more details.

Hence it's best practice to send email using SMTP authentication. But when sending email using that way you should have all credentials like email, password, outgoing server, port etc... and so you'll need a email that does exists.

  • I tried without using SMPT authentication. It got failed. I tried this way, "By configuring with authenticated login like [email protected] in configuration but to set the sender [email protected] with mimemessage.setfrom as mentioned here.http://stackoverflow.com/questions/1567467/setting-the-from-name-in-a-javax-mail-mimemessage I received mail from [email protected] but not from [email protected] – Arunkumar S Jul 19 '16 at 12:54
  • You can post what problem are you getting as a saperate question or you can append it in this question itself. Bottom line is you should always do it using SMTP authentication. Otherwise what's the use of sending mails when all of them are delivered to `junk` or `spam` folders? – Raman Sahasi Jul 19 '16 at 12:57
