IMAP Email Server on AWS

Too Long; Didn’t Read

Amazon Web Services (AWS) has determined that it is in their interest to block outgoing traffic on Port 25, the traditional SMTP port used for Internet Email. All other outbound ports are open for use. Amazon SES is the designated AWS workaround. For use only as an email server our instance does not require the other ordinarily present LAMP stack components, so Apache and PHP are not required. For example, we assume that you have a working basic install of Ubuntu 22 Server with the hostname set to a value similar to this template: mailyourdomain.tld
