I'm trying to setup a Sonciwall NSA 4500 at a remote office to probe my HQ, and in the event of a down probe, send an email to gmail. There is currently no local mail server in the remote office*.
I would like to set this up for direct SMTP sending from the SonicWall (as opposed to spinning up an SMTP relay server or linux node to run the probe.) For the life of me, I cannot figure it out. I have seen threads on settign the SMTP server to gmail.smtp.in.l.google.com, but this hostname doesn't seem to resolve.
I have used:
Mail server: smtp.gmail.com (as well as gmail.smtp.in.l.google.com)
I've tried all combos of authentication:
1. Enabling SMTP Authtication
2. Changing the port
3. Using the Authentication meathod
I'm interested that there is no option for TLS (although we can change the port, so...)
