vSphere Web Client E-mail Alerts - Can't get working
Running vCenter 6.5 using vSphere Web Center I've configured the SMTP Server, Sending E-mail address and in the advanced setting I've set the username, password and port. I assigned an alert for testing to e-mail me when a VM is powered on or off. I can see in the events that the system says it sent me an e-mail, however I never receive it. I've tried two different smtp/port/authentication configuration and neither has worked. I see no way to define TLS, but looks like its on by default.
How can I see the actual SMTP logs, so I can figure out what is going on? I've tried looking at /var/log/vmware/vpxd/vpxd.log on the vCenter server, but I can't locate an useful errors. Been using "more vpxd.log | grep SMTP" to look the huge log file.
If it help I'm trying to connect to Office 365 and an internal, locked down, open relay server used for printers and other devices.
