well, its a mobile device so it would actually make sense to download only last 20 emails and load more when needed.
No one wants to download 2-3 Gb of email data to a mobile devices and that would make sense only on PC.
and why are you using POP3 when IMAP is a lot better
Thanks for your input but I want an email app that gives me all of my emails.
Why bother reply if you have nothing comstructive to share?
It was constructive. POP email works by downloading full messages from the server, and due to data plans and storage size limitations, most folks would NOT want their entire mailbox downloaded to their device, just recent messages. My work email box is currently at ~3.5 GB, and I definitely don't want to consume that much of internal storage with old emails. I understand you may want more than 20 at a time...just that when using POP the amount of data you're downloading is a concern to many.
Using IMAP, however, is a better protocol for several reasons. For one, it is fully synced with the remote server, so you don't have to deal with messages in different statuses across your various mail clients. Also, IMAP clients only need to pull down the header info for messages until you actually open them, so there's a lot less to download if you want to be able to see your entire mailbox.
You may not have access to IMAP, but if you do I'd suggest it over POP3
Try the K9 app, its widely regarded as the best for non-Exchange accounts, and its free to boot!
I've used K9. It's simple in it's interface, but it is free and has a lot of configurable options when it comes to setting up POP3 and IMAP mail accounts, which is awesome. I believe K9 app is actually a branch of the original Android email app that was developed before GMail acquired Android...could be wrong about that though. Definitely worth checking out if you don't like the default email client.
