SuiteCRM email settings always provide authentication error - UCS on AWS EC2 + SUITE CRM

[hassepedro]

Hello suiteCRM Community,

Did install a UCS EC2 AWS solution and SuiteCRM on top of it. Did not configured anything on the UCS side, just follow the wizard. SuiteCRM seems to be working during the install process was obliged to run twice.

Now trying to setup e-mail communication using the e-mail settings options on suiteCRM and tried it with gnail and other email providers but always get failure authentication with no code on the logs. AWS outbound traffic is allowed.

You can get some extra logging with this

Problem to send a test Email [Performing Task - "One moment please..."]

Have a look at this send() function here there are several commented lines there that you can use to troubleshoot. This will help you see what is actually being sent out to the SMTP server, edit those fields for tests, and get a full SMTP log.
