AquaMail is an email app for Internet and Exchange mail, for Android 4.0.3 and higher.
Easy automatic setup for popular email providers:
Gmail, Yahoo, Hotmail, FastMail, Apple mail services (@me.com / @icloud.com), GMX, AOL, and more. Recognizes mail accounts hosted at Google Apps, Yahoo BizMail, and others.
Works with many other email services via standard Internet email protocols (IMAP, POP3, SMTP).
IMAP push mail (instant incoming email delivery) for those servers that support the IDLE extension (Gmail, GMX, AOL… not supported by Yahoo, for Hotmail please see the FAQ the app's web site).
Microsoft Exchange is supported via IMAP or EWS:
Exchange (EWS) accounts provide access to server side contacts (personal and global, with search), and Calendar sync. Recognizes mail accounts hosted at Office 365 and Exchange Online.
Plays well with other email apps that you may be using to access your IMAP or EWS mailbox. Uses existing folder structure, can synchronize drafts, sent, and deleted messages.

Can save attachments as files.

Rich text formatting when writing messages (including embedding images, in the signature too).

This is the Lite version, which is limited to two accounts, no identities, and adds a promo signature to all outgoing messages with a link to the program's web site.
You can add more than two accounts, use identites, and remove the promo signature by purchasing the Pro Unlocker app here on Play.
The app is available in (translated into) more than a dozen languages. Please see the web site for the list, a Google Play policy won't let me include it here.
