​Mmm, of course,  I should have read the error number :)
Will post back with other tests a bit later...

​I guess both methods are safe?
or is there some advantages with one or the other?

I'm using it within a Livecode Mail Composer.
Based on an export of my server DB, I'm scanning some address,
build dynamically the html-email and send one by one all emails.
