The AllowBogusHELO option is used like this:
O AllowBogusHELO=bool ?†? configuration file (V8.8 and later)
-OAllowBogusHELO=bool ?†? command line (V8.8 and later)
define(`confALLOW_BOGUS_HELO??, `bool??) ?†? mc configuration (V8.8 and later)
The bool is of type Boolean. If it is absent, the option defaults to true (do allow the hostname
to be omitted). If the entire option declaration is missing, the default is false (require
the hostname to be present).
The AllowBogusHELO option is safe. Even if it is specified from the command line, sendmail
retains its special privileges.
* Actually, the error reflects what was entered. If you entered ???EhlO??? the error would be ???EhlO requires a
domain name.???
