Using Magicspam some smtp accounts are rejected and some not

[nawak]

When Magicspam is enabled with default parameters, some smtp accounts are rejected and some works fine.
We use smtp authentication .

For example : on smtp.nawak.com user : julien@nawak.com works
on smtp.nawak.com user : smtp@nawak.com is rejected (only when Magicspam is enabled)

MAIL on my computer gave me this message :
READ Sep 22 11:29:50.174 [kCFStreamSocketSecurityLevelNegotiatedSSL] -- host:smtp.nawak.com -- port:465 -- socket:0x17d6af50 -- thread:0x15144f20
250-deb3067.oxyd.net Spam Protection provided by MagicSpam www.magicspam.com
250-PIPELINING
250 8BITMIME

What should I do to fix this problem and use Magicspam?

If you need more information don't hesitate to ask.

Thank's in advance.
Best regards.

Hi there,

We just tried sending emails to julien@nawak.com and smtp@nawak.com and got:

553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)

Please post your system setup (OS, mail system) and your user setup (anonymized).

Thanks.
