我有一个邮件服务器组成的postfix + dovecot + roundcube在debian挤压一些问题。
从roundcube发送和接收邮件运作完美。 但是我不能从Outlook等外部客户端发送邮件。 我仍然可以完美地阅读来自POP3或IMAP的邮件。 我总是有同样的错误，但我无法在网上find解决scheme：
client.hostname: Helo command rejected: need fully-qualified hostname; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=client.hostname 这是我的后缀的main.cf：

有人有什么想法吗？
在SMTP交易中，当有人向你发送邮件的时候，对话就从试图向你发送邮件的人开始，如下所示：
HELO rmotehostname.domain.com
你得到的错误：
: Helo command rejected: need fully-qualified hostname; from= to= proto=ESMTP helo=
是说他们发送的主机名不是完全合格的主机名。 因此，不要发送诸如“remotehostname.domain.com”之类的东西，而只是发送“remotehostname”。您拒绝这样做是因为您明确地在您的smtpd_recipient_restrictions设置了smtpd_recipient_restrictions 。
