smail, HELO hostname without dot

[joost@rulcmc.leidenuniv.nl (joost witteveen)]

The current debian smail (3.2.0.100-4) daemon does not accept HELO comands
with non-fully qualified hostnames. See the following, "rulvsa" is not OK,
whereas "rulvsa.leidenuniv.nl" is:

$ telnet rulcmc.leidenuniv.nl 25
Trying 132.229.1.33...

HELO rulvsa.leidenuniv.nl
250 rulcmc.leidenuniv.nl Hello rulvsa.leidenuniv.nl (joostje@rulvsa.leidenuniv.nl from address [132.229.1.77]).


The smail from bo still does accept the short hostnames. For this
reason, some people are unable to send me email.

Does anyone know who is breaking the RFC's? Is it our smail, or 
the mail clients that do things like "HELO rulcmc"?

Thanks,
