Seems clear enough and accurate to me.

I'll check over the libESMTP API document, this sounds like an oversight.

As designed, smtp_start_session should always set a meaningful error code, 
retrievable with smtp_errno, if it fails.  -ve values are taken from errno 
just after the point of failure.  +ve codes are libESMTP's own codes and 
include mapped resolver errors.  If smtp_start_session fails without setting 
an error code, that is a bug in libESMTP.  So, for example, DNS lookup 
failures will be always mapped to a +ve value and socket errors are always 
-errno just after the failing socket API.

Just in case I haven't said this elsewhere, smtp_errno retrieves the most 
recent error in the current thread.
