Youre very welcome

Yes, MailDroid does support several different mail accounts.
You can mix the crypto functions with each account, means you can use
GPG for account A and C, S/MIME for B and combine GPG and S/MIME for D.

I personally recommend the paid version of MailDroid, named "MailDroid
pro" as it has a bit more functions than the free app.
The costs are around 8-10 EUR.

Be aware that you need also the Flipdog CryptoPlugin, in which you
manage keys and certs. It has its own certificate store and acess the
device store as well.

Yes this problem is well known

If you have any questions please do not hesitate to write me. you can
also write directly if you prefer.

best regards from Austria
