#2 is a much weaker version of #1. It may have an earlier version of the mail include file which may be trapling on your newer ones somehow although I thought they were in different locations. Just reapply one of the mails with UE and upload the include files.
Use UE if you have it. Email Password was included in SecurityAssist in case they did not own UE as a quick substitute and shouldn't be used by people that own UE.
