Ignoring /etc/aliases with mailx

Question

Is it possible to ignore the alias expansion with mailx? I'm trying to get something sent with a null message body and don't want it to take the local username.

Answer 1

According to the man page it is not possible as it is not implemented.

But you could try sendmail -f "<>" to send mails with a null sender. Please note that with most mail servers the sendmail is an alias to their equivalent. It is not said to really use the sendmail of sendmail.

(I assume that your requirements are to send with a "null sender" and not with a "null message body")
