POP, IMAP, and WebMail
November 21st, 2008There are three ways available to access your email on our servers: POP, IMAP, and Webmail. Here’s how each works and some tips on which might work best for you.
POP: POP stands for Post Office Protocol and it’s easiest to understand if you think of the server as your post office. Mail is sent, the post office (server) receives it, and then your mail program (Outlook, Eudora, etc) connects to the post offices and picks up your mail. The mail is then saved on your computer and is no longer on the server. Just like when you receive a letter in the mail, you end up with the only copy of that letter, and you don’t need to go back to the post office any time you’d like to read your letter. If your mail is critically important I recommend running regular backups of your mail program if you use POP.
POP works well if:
- You use one computer to access your email.
- You are the only one who needs access to the email account.
- You have a dialup connection or sometimes work offline and want access to your email without being connected to the internet. (Not required, POP works great with always on connections like DSL or cable as well.)
- You want to keep your mail stored on your computer so you can easily back it up to an external drive or online service like Mozy.
IMAP: IMAP stands for Internet Message Access Protocol. IMAP works in an “online” type mode where you connect to the server for your mail and all mail remains on the server, instead of being transferred to your computer*. You can create folders on the server and move mail around, delete mail, etc. and it’s all being done on the server. With IMAP you can then access that mail from multiple computers. Depending on your connection speed and how much mail is stored in your account IMAP can be slow to access. All mail is backed up nightly since it’s stored on the server and we do nightly backups. However, we recommend also keeping a local backup of your hosting accoung if your mail is critically important and not depending on the server backups (a server backup can be run to restore an account but only the entire account, not one single email account, and occassionally we have to go back a few days or a week to run a complete restore).* There are some IMAP programs which can be set to allow you to save a copy of the email on your local computer. You’d need to contact support for your email program to find out if your program supports this.
IMAP works well if:
- You need to access your email regularly from multiple computers.
- You are on a fast, always on type of internet connection (DSL, Cable, or similar).
- You regularly clear out old email and are able to keep the email in your box under the limit for your account (never deleting email that’s stored in an IMAP account can cause you to hit your account limit and make mail bounce back to senders until the limit it changes or old mail is deleted).
Webmail: We offer three choices of webmail programs you can use (Horde, SquirrelMail and RoundCube). With webmail all mail stays on the server and you can access it from any computer that has an internet connection and browser. You login to webmail through your browser and can read and send messages through it.
Webmail works well if:
- You want to be able to access your email online from multiple computers.
- You would rather check your mail in a web browser and not deal with configuring a program on your computer to handle mail via IMAP or POP.
- You regularly clear out old email and are able to keep the email in your box under the limit for your account (never deleting email that’s stored in an webmail account can cause you to hit your account limit and make mail bounce back to senders until the limit it changes or old mail is deleted).
