Re: why cannot Aquamail open eml files, and some clients can do? Copyright
I just thought it would be better to show their content "inline" without the extra "tap" (required in the other email apps).
And never "got around" to implement opening .eml's.
Re: Can I exclude the attachment visualized when I forward a message
No, sorry. To Aqua, it's just part of the "parent" message's text content.
