Re: . NO [UNAVAILABLE] Temporary authentication failure

Guys, I have second problem:

If I use mail client (same as claws-mail), then I have this message in log:

554 5.7.1 <localhost>: Helo command rejected: ACCESS DENIED. Your email was rejected because the sending mail server does not identify itself correctly (localhost); from=<denis@example.ru> to=<mailuser@example.ru> proto=ESMTP helo=<localhost>

What do you think ? What is that ?
