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... Connected to rulcmc.leidenuniv.nl.

HELO rulvsa.leidenuniv.nl 250 rulcmc.leidenuniv.nl Hello rulvsa.leidenuniv.nl ([EMAIL PROTECTED] 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"?
