We have the Sendy (www.sendy.co) email newsletter system installed on one of our boxes, and one of the recent ASL updates has stopped the login screen completing. Switching off the modsec_10 rules allows the login to do it's redirect (it authenticates with sendy.co for its license) and lets the site load. Switching modsec_10 back on at this point has no adverse effects on the operation of the site thereafter (or that I've identified so far; not having started a send-out since hitting the login issue), so it appears to only be affecting the login procedure. (sendy.co and amazonaws.com with whom it auths are whitelisted globally for the license check etc.)

Does anyone here have any experience with sendy, or is there a list of the recent modsec rule updates (for approx the past two weeks) so I can narrow down which one I need to target?

Cheers in advance
