E-mail Command troubleshooting

E-mail Command troubleshooting

Hi,

Is there any way to troubleshoot e-mail commands processing?

We've always had a bit of issue with some mails not getting processed correctly, but it has gotten worse after updating to 14.3 from 14.1.
The emails are generated by a website form, so should be consistant in design/data. Manually mailing the helpdesk works just fine though, so I'm not entirely sure what's the difference.

We got "@@@" in the subject, which is removed as the email gets processed into SDP, so that far it seems to work even on the mails that have the issue.
We use "@@" as command delimiter.
The information we're trying to set is fairly minimal, and kept in the end of the form. Example of the relevant mail content:

##SystemParameters##
@@REQUESTEREMAIL=Test@testdomain.com@@

Thanks in advance for any input on the matter.
