Unable to send email via JavaMailInvalid Addresses message.

We have a FusionAuth server that refuses to send email. The handy email test tool in v1.16 tells me Unable to send email via JavaMailInvalid Addresses. What could this mean?

I'd confirm you can send email via the configured SMTP servers using the command line (swaks is a good tool) to take FA out of the equation.

It looks like "updating" the password with the same value it had before resolved the issue. Weird.

@dan can you please elaborate where to do this on command line?

@faizan

I'm not sure what you are asking for, but have found swaks to be a good tool for testing SMTP functionality from the command line.

Here's the swaks website/docs: http://www.jetmore.org/john/code/swaks/

Does that help?
