Disable spam/amavis on domain?

Hi all,
I've got a client who can receive emails from @domain.com but form the same server they got an ERP which sends email and are not coming through.
Under mail.err there is nothing while under mail.log I can see among others (changed IP and domains):

Code:

Oct  5 16:00:59 email1 amavis[1883]: (01883-02) Passed CLEAN {RelayedInbound}, [79.129.1.1]:63881 [79.129.1.1] <[email protected]> -> <[email protected]>, Queue-ID: 2B88A2300C, Message-ID: <[email protected]>, mail_id: KP7DXKAF-1Hu, Hits: -, size: 33394, queued_as: 9DE642300D, 266 ms

If I go to email accounts and disable completely the spam is it going to work?

 

Ops, sorry it was supposed to post it under ISPConfig. If admin can move it I will appreciate it.

 

If the e-mail is not delivered, is it still in mail queue?

Code:

postcat -qv 9DE642300D

What did your mail server do with that e-mail?

Code:

grep 9DE642300D /var/log/mail.log
