This bug is still present and annoys the admins, because checking these kind of details is the best way to block spam.
To cite http://tools.ietf.org/html/rfc2821: "The argument field contains the fully-qualified domain name of the SMTP client if one is available.
In situations in which the SMTP client system does not have a meaningful domain name, the client SHOULD send an address literal"
So if gethostname does not return a FQDN then please use the current IP as an address literal. (Even if that results in "EHLO [192.168.1.1]".)
The point in checking this field is not to get additional information, but to distinguish decent mail clients from spambots.
