I have an EC2 instance running the standard LAMP stack (Linux, Apache, MySQL, PHP). I am using PHP to send out a few e-mails a day (4 or 5 at the most). This is working without a hitch.
Every once in a while, I will need to debug or test some of the e-mails that are sent. To do this, I will run a particular e-mail sending script 10-20 times in succession. I noticed that some of those e-mails are never received by the listed e-mail addresses. This is sporadic and happens when the script has not been changed. I am assuming this is because EC2's built-in SMTP server is throttling my e-mails.
How do I view the logs for the SMTP server on EC2?
If your application is using your localhost as SMTP server, your logs should be in /var/log/maillog.
Note: There is a limitation from AWS for emails sent from EC2 instances:
AWS EC2 email sending limit when using third party smtp server
Amazon EC2 mail limit reached while using external smtp server to send emails

Setup: Node.js app running on EC2 Linux box. No outbound rules currently defined
Goal: To allow Node.js app to send email using AWS SES (via aws-sdk).
Issue: Cannot send email(running into timeout errors)
How should I go about setting up the EC2 security to only allow sending of emails via AWS SES?
Please refer troubleshoot SMTP timeout issues with Amazon SES document from AWS.
I'm wrote an java application that send Gmail SMTP messages from AWS EC2 Ubuntu, the problem is that google blocks any connection not authorized, Google delivery a page, to access from a browser, that enable access to Gmail from same IP of page access, but in EC2 Ubuntu there is no browser to SSH character environment. There are some way to set server ip to some Gmail permition list?
Just use AWS simple mail service instead.
I'm running a wordpress multisite install on a linux AWS ec2 server.
We're having some issues with emails sent via sendmail being blocked by the end user. The issue is generally not a problem with personal email accounts, more so with larger organisations with nasty firewalls.
At the moment, the server doesn't have a public domain name... So I'm not sure how to configure my php.ini file's sendmail_from
Any help would be great!
I'm running a nodejs server hosted on AWS (Ireland) and using emailjs to send emails. The email account I'm using is a gmail account and I can send emails from my local machine without any issues, but the emails fail to send from the production server.
Outbound firewall is set to allow all traffic on all ports.
The error message I get is "authorization.failed".
Gmail blocks IP addresses from AWS by default.
After logging into gmail locally, visit the following URL.
https://accounts.google.com/DisplayUnlockCaptcha
Once you verify that you want your AWS server to be able to access your gmail account then your server will be whitelisted.
I am building a ASP.NET MVC3 application that will be running on a couple web servers. Instead of each server/app sending its own emails(Asnyc) per request, I would like to leverage something like MSMQ and send messages to an email server that would pick up the messages and send an email.
I have an idea of how to do this with a console app, windows service and MSMQ but was looking for some direction from anyone who has had success/experience implementing something similar. Any guidance, experience, technology, blog posts would be appreciated.
From what I see you're simply after an e-mail relay service. You could just use a dedicated IIS to do this for you. IIS SMTP has builtin queued mail relay functionallity. Preferably you want to cluster this IIS SMTP service for max. reliability.
Regarding the consideration in the article linked I can't see the difference between the users page process waiting for sending a message to an SMTP server and sending a message to a MSMQ.
I believe when it come to redundancy you'll find it much easier to set up a clustered SMTP service than clustered MSMQ.
