LHLO support - rfc2033

[jocutajar]

Hi, I've just successfully integrated rustyknife into samotop as a second parser. I'd like to make it the default and swap out the PEG parser I've written.

One thing I'm missing is the LHLO command so that server can serve local delivery. With that perhaps also SEND, SOML SAML variants of MAIL to be feature complete for rfc821.

I suspect it should be trivial to add as the syntax is otherwise identical with EHLO/MAIL.

I don't plan on supporting obsolete RFC 821 commands at this time, you may submit a patch for these.

As adding LHLO support is trivial, I will add it.

Don't hesitate to provide any other feedback, I'm not exactly great at designing APIs :).

Thanks. You can check my adapter for rustyknife - I think the API is decent and I like how you solved the UTF-8/ASCII dilemma.

One thing is the nom Err - it would be great to re-export it so that dependent crates don't have to depend on nom just to act on the errors.
