Sending Email via using AWS SES - Timeout issues

dev google-group-archive
1

Using Lucee 4.5, I have a some processes that send batch emails out to a
set of users. Sometimes a few hundred emails will be sent. When this
happens, the first 10 or so will be sent fine and then the rest timeout,
and are added to Tasks that will be re-executed at a later time.

  1. The first question is why do you think I’m getting a connection timeout
    when sending emails via SES?

  2. The next question is there a way to detect this situation so I can
    notify an admin, or possibly run some code to re-execute the threads?

Looking at an email task in the Tasks page, here’s the error I’m getting:

email-smtp.us-east-1.amazonaws.com Could not connect to SMTP host:
email-smtp.us-east-1.amazonaws.com, port: 25; nested exception is:

Hi JP,

I use SES with Lucee no problem, but I have it configured to use port 587
with TLS enabled and this has never caused me any issues and I regularly
(more than once a day) send 1000s of emails at a time without issue. I
never had any luck using port 25 with SES, so maybe try the secure port
instead.

Kind regards,

Andrew
