New User Email Message password now always set to "both"

Yip I have got that as well when i tested it.

Thanks for this report. We are tracking this here: https://github.com/websharks/s2member/issues/689

Any idea when S2 will fix this bug?

I just replied to another support entry here regarding the same thing and recommended using the WordPress default in General Options > Email Configuration.

Is that the best option right now?

[edit] I changed my responses in the other thread and referenced the link above where the issue is being tracked.

UPDATE: Please see my summary of objectives here:
