Subduck:
It's all good, like I said, the problem (for me) is now resolved, and while it took time to do things, as long as the software on your end is being looked at, hey, that's all good. Maybe it was the differing paypal and order email address? I use my gmail account for things I absolutely NEED to get through, because it's not as strict as my own spam filters. Then again, with over 150 domains, I've got to be pretty strict on filters.
Another issue entirely:
For those interested in a usergroup limitation to this, I am in the process of putting this together and testing it out based on
this mod, some template hacks, htaccess mods and file renaming. If enough people are interested (and the integration author gives permission (I won't redistribute the LA files, but I'll tell how to get it working)), when I'm done testing I'll put up a workaround for it.
