@Daffy
I am using the same pkg you mentioned (mutt-1.5.21v0-sasl)
and that's my smtp rule
Code:
set smtp_url= smtp://mr.vieq@smtp.mail.yahoo.com:587/
I tried using port 465, but it keeps timing out.
using port 587, SASL authentication failed
//update!
To hell with yahoo!

mutt needs to be patched in order to use it with mutt, I moved all my stuff from yahoo to gmail and that's it!
