The fastest IMAP email client - Opera Mail for Linux
I was devastated when "upgrading" Opera on Kubuntu 16.04 only to find out the OPERA EMAIL component got removed. I sit with gigabytes of email, and by far Opera Email (using large IMAP folders) was the fastest
email client on the planet.
Please please please port the Opera Email application to Linux! You already have the source code from
the last version, if it cannot be ported to new render engine, please just extract it out of the old
version using the older render engine, and make it a loose-standing application.
Both Kmail and Thunderbird are MUCH slower than Opera Email, and Opera email (being QT-based), fits in perfectly with KDE Desktop.
Can the Opera Developers please comment on this plea?

We have requested this but it probably won't happen.
However, you can just run the old Opera 12 side-by-side with the new Opera, and just use Opera 12 as an email client.
Opera Mail is just Opera 12 with some tweaks to hide the browser stuff (which also introduced some bugs etc.). It was never finished and is no longer being worked on (besides the recent security update, which only applies to win and mac as there's no official *nix build). The version that's in Opera 12 works better.
You can still use Opera 12 for mail. In the advanced preferences under "programs and features", just add/set the http and https protocols to open in the Opera browser so links in emails open in the browser.
You can start Opera 12 with the -pd "path to directory" to make it use a specific profile folder if you want. You can put your old mail folder, contacts.adr, operaprefs.ini, wand.dat and opcert6.dat there. Or, just let it use the default .opera profile folder if the upgrade to the new Opera didn't take it over.
Disable updates to Opera 12 if it tries to force you to upgrade to the new Opera.
