hello dear experts

On Linux there are a few open source alternatives to the Thunderbird email client. There’s Evolution, KMail, Claws-Mail, Alpine (if you’re really old-school), and a handful of other clients (most of which, don’t live up to anyone’s expectations).

well i need to have encryption - so the question is:

should i use kmail as a alternative to tbird!?

but wait: i heard bout Geary, the new default IMAP email client for the GNOME desktop (and the likes of Elementary OS Freya).
Geary is an interesting beast. It offers a very low-key interface design ─ similar to what you might see in an Android app. It’s flat, clean, and incredibly easy to use.
Geary features:

A modern and straightforward interface

Quick account setup

Support for Gmail, Yahoo! Mail, Outlook.com, and popular IMAP servers (Dovecot, Cyrus, Zimbra, etc.)

Mail organized by conversations

Full-featured HTML mail composer

Fast keyword search

Desktop notification of new mail.

look forward to hear from you

and what is with webpg-firefox can i have a lean and lightweight replacement for tbird & enigmail with webpg-firefox
