Unable to get Zabbix to send e-mail alerts

[centenor]

Hello,

I've been troubleshooting our Zabbix for a while and can't seem to figure out what's wrong with my implementation. We installed a brand new instance of Zabbix 3.0 and have compiled it with SMTP & SSL support. We are trying to use Amazon SES to send e-mails. We've verified that user in SES and I believe I have all the information input correctly. The issue that I'm running into is that Zabbix never sends the e-mail. I just get an error that says "SSL connect error: Encountered end of file". We're using port 587 and SMTP credentials. I've verified all port connectivity is open between Zabbix and the SMTP endpoint.

I also set debug level up on Zabbix and all i'm getting from that is this

22068:20170515:092741.903 In send_email() smtp_server:'email-smtp.us-east-1.amazonaws.com' smtp_port:587 smtp_security:2 smtp_authentication:1

 22068:20170515:092741.909 * WARNING: failed to load NSS PEM library libnsspem.so. Using OpenSSL PEM certificates will not work

Also, we have setup Zabbix with HTTPS. To get that setup we just made a change in the Apache sites-enabled file that just points to the signed certificates. Not sure if that would be causing a TLS handshakes failure with the smtp server or not, but thought I should at least mention that.

Any help or feedback would be appreciated!

Thank you
