Need Quote: Improve Mail App

to display Mails in Nextcloud Mail App in text-only mode. This should be enabled, disabled with a switch in email account settings.

Current Mail App does not work well with HTML formated Emails (layout is broken) and with PGP encrypted messages. The encrypted PGP Block is not shown at all so it cannot copied to e.g. PGPApplet at all. In fact the mail app is not useable in its current state and some of my customers are turning away from nextcloud (e.g. to Bitrix24) because of this issue.

Will pay bounty, but need orientation and request a quote by experience nextcloud dev.
You may contact me via PN or via my website

Thank you in Advance

Save you money and install Roundcube. Is much more developed than the NC mail app (i have deleted it).
