Recently I started using Amazon SES. My first attempt was to use port 25, but I had a lot of connection problems. After some search I found that EC2 throttles port 25 traffic to avoid spam, so I changed to port 587, but from about 1000 daily emails, about five times I get SMTP connection exceptions in my application.
I'm considering it random because the few emails that fail are in different parts of the application and I didn't found any pattern between them.
My sending quota is 10000 and there are less than 50 recipients in the emails. Is it normal that sometimes sending fails?
Thanks in advance.
I'm using apache commons email 1.3.2 with the following settings:
setCharset("UTF-8");
setHostName("email-smtp.us-east-1.amazonaws.com");
setFrom("..."); // email from a verified domain
setAuthentication("...", "..."); // amazon smtp credentials
setSmtpPort(587);
setStartTLSEnabled(true);
setStartTLSRequired(true);
Exceptions:

Solved the problem by using SMTPS with port 465.
Commons Email doesn't seem to handle SSL well, since isSSL always appears as false in debug mode. So I overrided the send method from HtmlEmail:
@Override
public String send() throws EmailException
{
buildMimeMessage();
// Implementação padrão de send() não conecta corretamente via SSL
Transport transport = null;
try
{
message.saveChanges();
transport = getMailSession().getTransport("smtps");
transport.connect("email-smtp.us-east-1.amazonaws.com", 465, <<amazon SMTP username>>, <<amazon SMTP pasword>>);
transport.sendMessage(message, message.getAllRecipients());
return message.getMessageID();
}
catch(MessagingException e)
{
throw new EmailException(e);
}
finally
{
if(transport != null)
{
try
{
transport.close();
}
catch(MessagingException e)
{
throw new EmailException(e);
}
}
}
}
