I use qmail-toaster, and recently changed from using -H with tcpserver
to using -h, which looks up the rDNS name and puts it in the
With the former setup (-H), the remote portion of the CHKUSER log
message contained the helo value, "unknown" for the remotehostname, and
the remotehostip value.
With the current setup (-h, or blank), the message now contains the rDNS
name in place of "unknown", as expected. The helo portion though, is now
blank/null (missing). Is there some reason why the helo value isn't
shown when there's a remotehostname value present? Looks like a bug to me.
Many thanks, Tonix!
