Confirming (my recollection) that MTAs spend a lot of time looking for a fully qualified name upon startup. In old days, sendmail would hang for 5 minutes (or more?). The FQ part is perhaps surprising. Be sure you _have_ a fullname. Try hostname hostname -s hostname -f Perhaps GKRA can correct me but I seem to remember that a domain name without a suffix also causes a problem. Note that the domain doesn't need to be public or real -- it just has to be syntactically correct. I use sack-net.pvt.
