SMTP error 530 authentication required for my company’s domain to receive emails
I'm a network admin for a small company, and recently one of my users purchased an account with an email marketing company. She is going to use their website to send out a newsletter. When she tried to email the newsletter within our domain, no one receives them. However, when she emails them to @yahoo, @gmail, @hotmail, etc. it works. She received an email about the problem:
<mycomany's mail server> rejected your message
at the bottom of the page:
[my email]
[mycomany's mail server]#<[mailserver] #5.0.0 smtp; 530 SMTP authentication required> #SMTP#
