VCSA 6 Email alerts not working

This post was originally published on this site

I am trying to get email alerts from VCSA 6 working – to no avail. I am hoping someone here knows the solution?


<rant>I have opened a case with VMware support, but in most every aspect, the support representatives seem to know less about the VCSA than I do! Moreover, some of the KB articles they have suggested have blatant and obvious mistakes! Take for example VMware KB: Emails sent from VMware vCenter Server Appliance are rejected , the file is mis-represented and not valid in the format VMware presents it! It is missing quotes FEATURE(genericstable)dnl which render the remainder of the file invalid!</rant>


Does anyone have an idea what’s going on, or have email successfully configured on VCSA?


I have the following situation: VCSA 6 with open-relay SMTP (no authentication, any email address from my IP). On the VCSA 6, all /var/log/mail* log files are empty.


I have tested port connectivity to with :  curl -v telnet://target ip address:desired port number (VMware KB: Using Curl to test port connectivity in VMware vCenter Server Appliance)


Here is the redacted transcript of a failed email from: /var/mail/root
