You got me there. I'm using plain old sylpheed (2.6.0). In using sylpheed, I treat it like a word processor, don't hit enter until I end a paragraph. Just googled 'sylpheed line breaks' and does seem to be some missives on line breaks and auto-wrap, bugs and so forth, I will investigate. If anyone else sees this, I can change over to claws (or something else) fairly easily.

Doing a bit more research into Unattended-upgrades, I must admit I just can't find documentation for apt besides the basic Ubuntu and Debian howtos. If anyone can point me to good apt docs in regards to /etc/apt/apt.conf.d and it's requisite files, I'm all ears.
