I have gigabytes of mail on my own computers dating back farther than that.

Which is precisely why I don't use IMAP. IMAP and POP are both just protocols. But the clients that implement them tend to enforce different expectations of how they are to be used. I'm using Thunderbird, which is pretty popular. (I used to use Eudora, but its IMAP was not good enough to consider; that program enhanced POP to its limits.) For POP, it simply assumes that you're downloading the mail to your client, keeping it there, and deleting it pretty soon from the POP server. The server, then, is one simple holder for new mail, and it doesn't need to store much -- a few weeks' worth, if that's what you set the delete-after time to. It's well suited for ISPs.

But Thunderbird, like some other clients, assumes that IMAP is only used when the server is the final permanent storage place for mail, and you thus can't delete it from the server without deleting your local copy, which is just a cached, sync'd copy. The server has folders, and mail is manipulated there via IMAP. This is how some corporate mail systems do work, where everyone at their desk at the company building is on the LAN, and thus IT manages everyone's mail carefully. But it's not how an ISP would probably want to work! It drastically raises storage requirements.

Of course it is theoretically possible for a client to use IMAP as a smarter POP, adding some useful capabilities (which Eudora had) that standard POP omits. But often they just assume that if you use IMAP, your mail is on a corporate server, period. Bad design.

A smartphone typically doesn't have much storage so it might be better off using IMAP to peek into the current server-based mail that a wireline-based client program might then pull down using POP. You usually don't archive mail on a smartphone. So a smartphone app might make better use of IMAP then Thunderbird does, and IMAP could be the better choice of protocol. But it's not a clear cut answer. It looks as if the Verizon Android Mail app has its own server which goes in between the phone and the actual mail server. So the Android link to Yahoo mail drops every so often even though their POP server works and their own app probably does too.

    Well, thanks to our new server people we can offer both. Our old
    provider wasn't able to do IMAP until real recently. So it works
    both ways. On the iphone deal I map not a big deal, its just the
    other settings that get skewed
    thanks

    Just curious if others have been having the same issues with
    IPhone over the last few weeks. I think I have seen it in the
    past, but for the last 3 weeks I have been getting calls, I think
    due to a recent update, of users having email issues with their
    Iphones. When we walk the customer through the settings, account
    types were switched from pop to IMAP, outgoing security had been
    changed, as well as server ports. Settings that would never,
    usually, be changed by the users. It doesn't help that these
    happened during a mail conversion we were doing right before. No
    calls on droids. Anyways, if this is true due to a IPhone update,
    is there a way to tell the phone not to change?
    thanks
    heith
