    Sorry, no - this can't be the case. If lankheet.com is a local domain no
    relay entry in the access_db is needed. Aren't we speaking about mail
    sending? You are sending from the Sendmail host itself or through it
    (acting as a relay)? If first, then 100% you have a misconfiguration. If
    last, then the error should be "Relaying denied" and not "sender address
    does not exist". This too indicates a DNS/Sendmail misconfiguration.

    And not now required.

    All local domain names must be stored in local-host-names. Else Sendmail
    does not know that a domain is a local one. A relay entry is only needed
    for non local domain names which you want A) relay to (i.e. because you
    have a front MX and a back MX - relaying and using mailertable then) a
    specific domain or B) mail from specific domain users (i.e. in house
    relaying for all office members).

    echo '$=w' | /usr/lib/sendmail -bt

    That lists all domain names in class {w}. All your local domains must be
    in there. Be aware that keet.lankheet.com is not the same as
    lankheet.com for Sendmail!

    I bet you still have a DNS <--> Sendmail misconfiguration problem.
