Hello. I've configured mutt to view .xlsx attachments inline if they're not too big.
Here is my configuration: ~/.mailcap: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet; ssconvert --export-type=Gnumeric_stf:stf_csv '%s' fd://1 2> /dev/null | column -s, -t; copiousoutput; description="Microsoft Excel Spreadsheet"; nametemplate=%s.xlsx ~/.muttrc: message-hook ~A "source ~/.mutt/message_default.rc" message-hook "~z <500K" "auto_view application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" ~/.mutt/message_default.rc: unauto_view application/vnd.openxmlformats-officedocument.spreadsheetml.sheet It works quite well, except that when I open a message with big attachments, .xlsx files are not displayed inline (as expected), but the mailcap command is still run. I can see that with "top". So I have to wait for a long time before I can see message's body, which defeats the purpose of the message-hook. Is it possible possible to avoid that? Did I do something wrong? -- Bernard Massot
