Am getting this error in catalina.out log file when users try to get a password reset sent to them.
[ERROR] com.concursive.commons.email.SMTPMessage - javax.mail.MessagingException: 501 Syntax: HELO hostname
[ERROR] com.concursive.crm.web.modules.login.actions.Login - Forgot Password -> Send error: javax.mail.MessagingException: 501 Syntax: HELO hostname
The local smtp server is running and requires no authentication (have confirmed with both a test email locally sent and event telnet:25 hand-crafted email sends too. I note that when I try to delete the username and password in the admin SMTP configuration page they automatically return when I go back in to check. The email is not sent however, how to fix this? Will they get sent again once the issue is corrected? Can I see a queue somewhere?
