If you’ve tried setting up your mail client and are struggling getting it to send your emails, you’re most likely dealing with what’s called an SMTP (Simple Mail Transfer Protocol), or outgoing mail server. The mail client will ask you for your “smtp server” but we continually get messages from readers that they’re left scratching their heads as to what that is. We are continually updating the list of outgoing mail servers below based on user requests. The table includes outgoing mail servers from around the globe. We’ll also show you how you can skip the need for an outgoing server altogether, which is especially useful if you’re on the road.
