Error message MUST COMPLETE IMAGE PUZZLE BEFORE SENDING is seen periodically when using AOL as email provider



Using AOL as email provider the following error messages comes every two days:

2014-06-12 15:11:06 E-mail was NOT sent: 521 5.2.1 MUST COMPLETE IMAGE PUZZLE BEFORE SENDING. PLEASE GOTO


SmartStruxure Lite MPM



This is AOL trying to stop people using it's email service to generate spam, you are now required to periodically enter a series of numbers or letters from a web page in addition to normal username and password authentication.


See AOL help to understand the issue further. This post on the internet also notes the issue and unfortunately this is something that AOL have added and is not under our control.
