Smtp 550

clausbc
Hi,
I have SMTP proxy enabled on a ASG120 with no active AV or anti-spam licenses. Nevertheless I get:
 : host mail.domain.com[***.***.***.***] said: 
550 > 91.198.169.19>    is not allowed to send mail from mail.dk (in reply to RCPT TO command)

Why is that? And can it be avoided?

/Best regards
Claus, DK

    In the first 30 days, it's possible to configure "pay" portions; Astaro isn't perfect at turning that off when the license is applied.  I think this is a situation where you need to contact Astaro support.

    Cheers - Bob

    This does not sound as Anti-SPam to me, more like a SMTP-Relay protection. 

    Which means that you need to configure which domains the SMTP proxy is allowed to access and to which internal mail server he should send it to. 
    AND you need to configure which internal hosts are allowed to send email to external server (relay it). 

    If an external host wants to send email to a non-local, not configured domain, you get the following email message.

    Means:
    I can't really see it from the blacked out log, but is this an incoming email to the AStaro or an outgoing email from the Astaro to another SMTP server on the internet?
    Is the blocked ip adress internal or external?
    Is the target domain internal or external?
    Should the blocked ip be actually able to send an email to the domain?

    thx Gert
