FAQs About SMTP Hosting

What is SMTP?

SMTP stands for simple mail transfer protocol. It is the standard protocol used to send email messages.

How does SMTP work?

When you compose and send an email message, your email software opens a connection to an SMTP server. This normally involves logging in using a password.

To transmit the email, your software sends text-based commands, including details about the sender, recipient, and content. The server confirms each command, and once the message has been received successfully, it uses DNS records to find out the IP address where the email should be delivered.

Is SMTP secure?

Not always. If you want to ensure that nobody can read your emails in transit, use PGP encryption.

What is the difference between SMTP and POP3/IMAP?

SMTP is for sending email. POP3 and IMAP are for receiving email.

Are there any alternatives to SMTP?

There are some vendor-specific alternatives to SMTP, but these aren’t offered with regular web hosting accounts.

Where do I find the SMTP settings for my hosting company?

Before you sign up for a web hosting account, check that email service is included. Some hosts do not allow you to create email addresses alongside your web hosting files. Assuming you can create email addresses, you must create mailboxes in your hosting control panel. Then ask your host for the necessary server information to connect to it.
