Internet Providers Should Find Their Way to IMAP
Rob Pegoraro, Washington Post 2004-03-23

If it weren't irreplaceable, e-mail would be intolerable. Spam and viruses are

all a pain, but the biggest hassle with e-mail is simply managing the volume of

it all.

Answer this, forward that, file the other thing -- then try to keep track of it

all on more than one computer: It's like a checkbook that will never be

balanced.

A big part of this problem is the way most people check their e-mail -- an old

standard called Post Office Protocol, POP for short, that was developed for a

far simpler time.

If we downloaded e-mail to only one computer, POP would still work. But between

work and home computers and Web-mail options, it's easy to have three different

routes to one inbox -- something POP was never designed for at all.

Trying to check a POP account from two computers is always a mess. If you

download each e-mail to only one computer, you lose track of who sent you what.

But if you keep your messages on your Internet provider's computers until

you've copied them to every machine you use, you can expect that mail server

will eventually forget which messages you'd already retrieved, sending down

fresh copies of every one and flooding your inbox with duplicates.

A better mail setup that solves those problems was developed over a decade ago

and has been tested extensively since. But IMAP (pronounced "eye-map," it

stands for "Internet Mail Access Protocol") suffers two flaws of its own: One

is that most Internet providers don't offer it. The other is that most users

don't know it exists.

I can't do much about the first thing, but this is my attempt to change the

second.

Like POP accounts, IMAP allows you to use the e-mail program of your choice.

Unlike POP (but much like Web-mail), IMAP gives you the ability to access all

of your e-mail from wherever you log in, while also tracking what you've done

with each message.

So you can check your e-mail from different places, yet never lose your place.

Log in from every computer you use, borrow a friend's e-mail program, or use a

Web-mail interface -- and every time, you can pick up where you left off by

seeing which messages you've read, replied to, forwarded, flagged for follow-up

or filed away in their own folders.

You can even start writing a message on one computer and finish it on another,

since an online Drafts folder is a regular feature. So is a Templates folder

for your stationery.

Spam and viruses are easier to deflect, since your mail software can peek at

each new message before downloading it, then wipe it off the server before it

gets to stain your hard drive. But if your computer does get wiped out by a

virus, you won't lose your e-mail from it.

This setup functions best over broadband connection, but since IMAP mail

programs can automatically "mirror" your online folders on your hard drive, it

works over dial-up too. Even if you can't get online, you can still see every

message that had arrived when you last checked your mail -- unlike Web-mail.

Finally, when you do want to archive e-mail -- for example, when your account

starts to bump up against its disk quota -- it's easy to move messages to a

local folder on your computer for permanent storage.

The odds are that you've used something like this once before. America Online's

mail system was built on similar principles, and it remains one of the

company's biggest advantages over its competitors. (In one useful aspect, its

ability to store your address book online puts AOL ahead of IMAP itself.)

Making use of IMAP means finding an amenable Internet access provider. AT&T

Worldnet, Comcast, EarthLink, Juno/NetZero, SBC Yahoo and Verizon all offer

only POP and Web-mail access.

The usual explanation is that consumers don't want IMAP, and it would cost too

much to offer anyway.

"We haven't seen a large demand from the pure consumer segment," said Stephen

Currie, EarthLink's director of product management, in an e-mail forwarded by

the service's PR department. He also noted the added processing capacity and

disk costs needed by IMAP, concluding, "I don't think it would be feasible to

offer a mainstream free IMAP product."

Further down the food chain, however, many smaller providers are doing just

that.

For example, three local firms, Silver Spring-based Atlantech, PatriotNet in

Fairfax and Rockville's Heller Information Services, reported that anywhere

from 15 percent to a third of their customers had switched to IMAP.

What's particularly impressive about those numbers is that two of these firms

barely mention their IMAP support on their own Web sites. That's typical;

you'll probably have to ask your own provider if it offers this option.

Should your provider be so enlightened, switching to IMAP will involve noting

the change in your e-mail program's setup screen.

The quality of your software, however, may be an issue in its own right. Two of

the most widely used mail applications, Microsoft's Outlook and Qualcomm's

Eudora, suffer from strangely sloppy IMAP support. The Mozilla browser's mail

component, Apple's Mail program for Mac OS X and Microsoft's Outlook Express

work better -- but even then, little defects such as Mail's habit of creating a

"Sent Items" folder instead of using the standard "Sent" folder for outgoing

messages can lead to confusion.

But these problems should all be solved in the usual course of development;

someday, every e-mail account will work like this. Until then, IMAP should be

on your shopping list the next time you look for an Internet service.
