Hi,
I have a problem when send e-mail from a e-mail client to external domain managed by my server:
client use test@xxxx.com send a mail to test@yyyy.com using outlook express, if test@yyyy.com is an external domain not configured in my IredMail panel is ok, but if test@yyyy.com is configured in my panel, i can see in /var/log/mail:

2013-08-30T09:15:27.197705+02:00 mx1 postfix/smtpd[14603]: NOQUEUE: reject: RCPT from unknown[151.12.xxx.x]: 554 5.7.1 <test@yyyy.com>: Recipient address rejected: Invalid HELO/EHLO; Must be a FQDN or an address literal, not 'DENIS'; from=<test@xxxx.com> to=<test@yyyy.com> proto=ESMTP helo=<DENIS>

i have tried to add ip address in /etc/postfix/main.cf but I have same problem.

how can I do?

thanks

Marco.

Re: invalid HELO/EHLO

1) Please show us output of command "postconf -n" to help troubleshoot.
2) Do you configure your mail client to perform SMTP auth before sending email?

2) yes, client is configured with SMTP auth, and dovecot relay correctly any email, but if destination domain is configured on my server no.

You can Help me?
Thanks.

Re: invalid HELO/EHLO

No idea yet. Could you please show us Postfix log for the full smtp session? Starts with 'connect from xxx' in log.
