Problem solved with 0.9.0.
Thx for your advices and answers

@Julian : Yes

@psychobunny : Nope, i have a message like this "No email was sent, no emailer plugin was installed" (my Nodebb is offline, I can't test)

@yariplus : yes, i did that
@AOKP : do you know when will be released the 0.9.x ?

For example, I asked to follow this topic, my email is valid, no mail in spam => no mail about answers

Hi,

I have installed NodeBB v0.8.2, but, I can't send any email

I have tried :

• nodebb-plugin-emailer-mailgun
• nodebb-plugin-emailer-sendgrid
• nodebb-plugin-emailer-mandrill

But after reload/restart, I still have this message "Emailer not installed"
Did I miss something ?
Do I activate another plugin before ?

Thx for your help
