[BUG] Email.AttachFromFilename does not dispose stream

[asherber]

It seems that GitHub won't let me fork this repo, because I already have a fork of lukencode/FluentEmail. But please take a look at lukencode#384 and implement that fix here -- disposing of the file stream after reading the file to attach.

Do you know if anyone is working on this already? if not, I can work on it.

There's already a suggested fix here. I just can't fork this repo because I already have a fork of the source repo.

Thanks! I'll review and get it in ASAP. You should be able to fork into a differently named repo though.
