Troubles with Mautic setup on AWS SES with domain on Wix

Your software
My Mautic version is: 4.2.0
My PHP version is: 7.4.28
My Database type and version is: 10.3.34-MariaDB

Your problem
My problem is: The test connection on the email settings gives the following error:

Connection to tcp:// Timed Out Log data: ++ Starting Swift_SmtpTransport !! Connection to tcp:// Timed Out (code: 0)
++ Starting Swift_SmtpTransport !! Connection to tcp:// Timed Out (code: 0)

Steps I have tried to fix the problem: My domain in AWS SES has been verified, I didn’t set up any ‘Custom MAIL FROM domain’ because my DNS provider Wix doesn’t let me (or I can’t figure out how); in the SMTP settings part of AWS I created a user with a password, considering that the interface changed from the one that appears on the videos from YouTube, I did it the simplest way I could. I tried different port connections on Mautic; I changed the ‘Service to send mail through’ option from ‘Amazon SES’ to ‘Other SMTP Server’ and added down below the ‘SMTP host’ which appears on the page of AWS ‘

I basically checked out all the videos in YouTube that I could find with the search “AWS SES Mautic SMTP” and the queries from Google didn’t prove much useful.

Have you tried connecting via api rather SMTP? Its an option in the drop down for amazonSES config. Requires a slightly diff config on Amazon SES.

I would use API instead of SMTP on AWS SES.

I know most tutorial on internet setting up AWS SES API on mautic is outdated but try setting it up anyway. The AWS dashboard in tutorial is what outdated so you will have to do some digging around in AWS to get it all sorted out and working on API.

With API, you can also set up bounce and unsubscribe which I think is easier than setting up on SMTP anyhow.

I wrote this rough and ready guide to remind myself each time I do it.

On DNS server - we need to add amazon ses cnames to DNS
