SMTP ISSUE 501

[angelochen]

Hi,

Setting up roundcube with a local exim4, got 501 error when sending, smtp log shows:

[14-Oct-2017 11:43:01 +0800]: <feajiaon> Send: HELO _
[14-Oct-2017 11:43:01 +0800]: <feajiaon> Recv: 501 Syntactically invalid HELO argument(s)

do define the 'smtp_server', like to know where to update to avoid the underscore after HELO, Thanks,

A

found the issue:

the nginx config needs a :server_name  example.org;  although there is no virtual host, round cube is the only one.
