Hi,

When there is not reverse for the hostname, the gethostbyname return 
NULL. There is no check of the return value in the function 
hostnamestr() (strgen:144). Because of the SIGSEGV generated, the normal 
might not working.

Here you can find a patch, the hostname is used in the HELO part. It 
might be interesting to specify the hostname in the config, for the 
moment, I had a patch that use the non reversed hostname if the 
hostnamestr return NULL.

Under Slakware, the hostname command return the first part of the FQDN 
hostname.
