I’ve been using Gmail’s “send mail as” feature for years but now they require you to use your own external server (Since last 2014 apparently) when setting up a new address.
My mx records for inbound are setup and forwarding to my gmail account just fine, now I need to get the outbound working.
Has anybody successfully set this up? Which ports do I use? Can I just use 25? I’ don’t really want to go to the expense of buying an SSL certificate.
Any and all help greatly appreciated…
