OSEM pulled last week confirmation email seen as SPAM

[redimido]

Hi,

My ISP's anti-spam tool is detecting the registration confirmation email as SPAM, with this headers in the email source:

X-Amavis-Alert: BAD HEADER SECTION, Improper folded header field made up
    entirely of whitespace (char 20 hex): X-Spam-Report: ...that system
    for details.\n \n Content previ[...]
X-Spam-Flag: YES
X-Spam-Score: 2.201
X-Spam-Level: **
X-Spam-Status: Yes, score=2.201 tagged_above=-999 required=2
    tests=[HTML_MESSAGE=0.001, HTML_MIME_NO_HTML_TAG=0.001,
    MIME_HTML_ONLY=2.199] autolearn=disabled

how can I prevent this from happening?

By the way, we are new to OSEM. Loved the high amount of quality work you guys have put on it, and are looking to help back at least on the translations area.

I am receiving feedback about this issue. Most of the submitters are finding their emails in the quarantine because this header field.

One of them commented the score is pretty low, mainly because of this field.

Please raise the importance so this is fixed sooner
