I wouldn't necessarily call this a vulnerability. I ran into this when writting the Regex Scanner for QSQ. Find $skip_text_msgs and set it to 0 so that all e-mails, including plain text, are scanned. This only applies to the 1.2x versions, 1.1x don't have this feature. John Narron|

No I don't call it a vulnerability. The skip_text_msgs feature, intended to skip messages that just seem to be plain text, improves performance by not scanning messages that don't appear to have binary content. Admittedly, yes, its not perfect. Not being a user of QSQ 1.2x, I don't know if this
