Android Question SMTP Email Send: To must include at least one recipient

I keep crashing on SMTP Email Send with TO must include at least one recipient

WHO is placing this restriction on Send?

I have 3 email address in the BCC's but none in TO.

I do not want anyone seeing who is getting this EMail.

In real life I do this all the time (Sending Emails with CC's or BCC's and NO To's)

So is this a BUG? An Android Restriction? Or a Restriction of this SMTP library?

BCC's should be considered as a TO:


IS there a way around this (of course without including a TO)
