Hallo, Andrzej,

Du (anfi) meintest am 27.03.08:

>> 'grep you custom-sendmail.cf for word alias and post the
>> results'

> Next test:
> praliases -C _your_custom_sendmail_cf

On my system: no answer (no error message)

in "/etc/mail":

praliases
praliases -f aliases
praliases -C sendmail.cf
praliases -C submit.cf

all commands send no answer.
"aliases" has 11 entries. "sendmail 8.14.2"

Viele Gruesse!
Helmut
