I like using thunderbird to have all my emails in the same place, in a unified inbox. This doesn’t allow me to access my inbox on my phone etc though, so I’m looking for a FOSS way to solve this problem.
My idea would be to selfhost a website, like a webmail site, that has the functionality of connecting to different mail servers and unifying the inbox to get all my mail in the same place. Should be accessible by android phones and iPads.
Is there a better way to do this? Maybe with nextcloud? If anyone has an idea, let me know.
Tested Stalwart, the all in one option with both JMAP and IMAP. Looks fairlygood, works fine with IMAP and SMTP, but making it work with JMAP clients took me some time. This page helped for the F-Droid client lrr.rs. With Cypth it was a no go. SnappyMail webmail software is not mentioned on the JMAP clients page at all but it is with development 1/2 done with JMAP implementation. In a few months time Stalwart is expected to have a web interface for admins. Looking forward to testing again when that is available.
