(neo)mutt/mailhandling best Practises in Qubes

[799]

Hello,

I have moved most of my email workflow in Qubes to a dedicated Email-AppVM.

It has DavMail and Thunderbird + neomutt installed to access our Corporate Exchange Server.

(Thunderbird is only used when I need to paste screenshots into an email, for example for troubleshooting/howtos etc)

I'd like to know how other users have configured their mailcap-file in (neo)mutt to handle file attachments.

Currently I am opening HTML attachments/mails in a disposable VM which fires up qutebrowser and I tried to handle docx/xlsx/PPT/pdf attachments the same way.

Can someone share their mailcap-file file to get an impression what should be in there?

Another topic:

I'd also like to use a dedicated Key Combination to open a file in my work-appVM.

The workflow I came up with:

1) Check Mail with neomutt (plain text power)

2) open attachments in disposable VMs

3) if I need to work on an attachments, after checking it, open it in my Work-AppVM (which is separated from my workmail-AppVM)

Does this makes sense from a security perspective or is it overcomplicated and I should merge mail and document editing into one VM (browsing the web is always done on another Work-Internet-AppVM).

Hi,
I'd be interested in best practices as well. I'm using offlineimap + neomutt + msmtp in an AppVM for my emails.
I do HTML rendering with lynx in the email AppVM. Since it doesn't do JavaScript I don't see a reason for me to fire up a disposable VM for the HTMl emails that I receive.
I usually save attachments to disk and then open them in disposable VMs. Therefore my mailcap file is rather sparse:

text/html; lynx -assume_charset=%{charset} -display_charset=utf-8 -dump %s; nametemplate=%s.html; copiousoutput

Best regards
