Comment 49 for bug 303140

Hi everybody,
more or less daily I send out emails with attachments, and I like the idea of having my emails signed. But the attachments are blowing up my email folder size on hard disk, so I have to stop signing them. And I want to read them in 25 years still without any special tools installed.
Please make it possible to remove attachments from sent and signed emails. All I need is, that the recipient receives my emails signed - I don't need them signed on my own system (a flag showing "Sent signed" would be sufficient). The same applies to encryption.
I'm using Seamonkey myself, but hope to get this fix one day from Thunderbird into Seamonkey (or I will switch to Thunderbird for the case there will not come any update to Seamonkey anymore).
Friendly greetings,
Torsten
