I use Amazon SES as a mail relay service for my emails as my server host blocks connections out on port 25. SES works great, however occasionally users send large attachments (>10MB). Whilst I could just every time suggest they upload their attachments somewhere and send a URL, this becomes tiresome and sometimes too complicated for my users.
I'm thinking this is really really super simple, but I can't figure out what I need to do. I don't mess with Postfix much (Just let it run and do its thing) so I've got no idea where to even start with this.
We have postfix currently configured to relay all mail out through SES using the code below.
I installed postfix on a bare bones Ubuntu Server 12.04 by typing the following in the terminal.
sudo apt-get install postfix
When asked to choose a mail server configuration type, I chose Satellite system. For the System mail name, I entered ww1.example.com and for the SMTP relay host, I selected mail.example.com. Note that I replaced example.com with my own domain.
