Hello to everybody, while we use the option "reject_unknown_helo_hostname" we noticed, that single hostnames will be rejected without contacting the dns-servers. After some debugging of the source code we got to this line:
226 _res.options &= ~saved_options; where the flag "RES_DEFNAMES" will be negated and so no domain-information will be added to the hostname. We would like to know why "saved_options" is negated here. Shouldn't it only be a logical AND? Is there any option to control "RES_DEFNAMES" from the configuration-file? In my opinion it is only useful to negate saved_options if "reject_unknown_helo_hostname" covers the option "reject_non_fqdn_helo_hostname". Am I correct? Great Regards, Timo Schilling
