Hi everyone. I'm new to the list and I'm trying to gather some information
about Postfix for my documentation notes. I looked all over the place to try
and find the answer to this question, but I was unable to, so I thought I
would ask the list.
Will Postfix always accept mail from null senders by default or is there
something I have to add or change in my main.cf file to make Postfix do
this? Thanks.
Hi,
$ cat check_null_sender.pcre
# check_null_sender.pcre
/^<>$/ YOUR_OPTION_HERE
$ grep check_null main.cf
check_sender_access pcre:/etc/postfix/check_null_sender.pcre,
In the appropriate restriction place.
Justin.
