ssmtp -t doubles '\r\n' line endings

[Patrick Gerken]

I use ssmtp with alot.
Alot normalizes mail endings according to rfc 3156.

One of these normalizations consists of converting all '\n' to '\r\n'
When such a message is passed to ssmtp, ssmtp magically doubles the line endings.
'\r\n' becomes '\r\n\r\n' whereas '\n' stays '\n'

So my mails have every '\r\n' line ending doubled. What I expected, was that the line endings do not get doubled.
