Hi, I want to create an sendmail smtp-auth server that does nothing but forwards e-mail based on smtp-auth. Is this configuration correct for that purpose or is there another smarter way? This works but I don't know if it's an allowed way to use nullclient. The content of sendmail.mc OSTYPE(`linux')dnl FEATURE(`nullclient',`my.mail.gateway')dnl undefine(`ALIAS_FILE')dnl define(`confPRIVACY_FLAGS', `authwarnings,novrfy,noexpn,restrictqrun')dnl define(`confAUTH_OPTIONS', `A')dnl define(`confAUTH_MECHANISMS',`PLAIN LOGIN')dnl TRUST_AUTH_MECH(`PLAIN LOGIN')dnl Regards /Lars -- Psyche-list mailing list Psyche-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/psyche-list
