Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I am trying to send a mail from my website through port 587. I verified the credentials and even tried to send the email from Gmail by adding the account there and sending through it. On Gmail it works, on my server it doesn't

I get the following error :

{ [SenderError: Mail from command failed - 501 5.5.4 Invalid Email address] name: 'SenderError', data: '501 5.5.4 Invalid Email address' }

I am using nodemailer to send the mail

Can anyone give me some information about this error message ?

Turns out the module that sent the email didn't specify a from field and it was sending it blank. The Outlook smtp server wasn't tolerant about this and threw an error.

Specifically adding from to the email solved the problem
