I am trying to change my sendmail configuration to deliver all "user unknown"
emails to a specific account (baduser).
I added the DL definition to sendmail.mc and generated test.cf.
Then I tested this new config using:
echo who | sendmail -v -Ctest.cf noone
and the email was correctly delivered to the defined account.
I then renamed test.cf to sendmail.cf (in /etc/mail) and retested with:
echo what | sendmail -Csendmail.cf noone
and again the email was delivered to the baduser account.
Happy with this, I then restarted sendmail (via systemctl) and sent yet
another email to an invalid account.
Instead of the email being delivered to baduser, I received a 550 5.1.1 user
unknown reject email.
What have I missed here.
(Fedora 22 & sendmail 8.14.7/8.13.3)
What You mean by "DL definition"?
IMO what You want is configured by defining macro "LUSER_RELAY", as:
define(`LUSER_RELAY', `local:baduser')
And, it seems as You are using old sendmail versions with F22:
v8.14.7 was semewhere in F18/F19, and sendmail v8.13.3 in Fedora 4 (ten
years ago!). It has any reason?
That is how I set the DL definition.
I have tried this experiment on two different servers and managed to give the
wrong combination of versions.
What I actually have is one box with Fedora 22 and sendmail 8.15.1/8.14.4 and
the other with Centos 7.2.1511 and sendmail 8.14.7/8.13.3.
The results are the same on both boxes.
Further experiments show that running sendmail from the command line (eg
sendmail -bv noone@xxxxxxxxxxxxxxx) gives the correct result (delivery to
baduser) but when running as a normal daemon I get the reject (again on both
boxes).
Any ideas?
This directive should be sufficient. Not sure how about its order in
'sendmail.mc', usually I give it somewhere towards the end of the file.
Local user ('baduser' here) must, of course, exist - but it may be
an alias to real name.
It is not possible, that your /etc/mail/{mailertable,virtusertable}
values cause this mail rejecting?
You test it from commandline as root or as ordinary user?
What about selinux?
What You have in your /var/log/maillog and /var/log/messages (or in
journald log, when you are using this bullshit advancement)?
I'm pretty confident that the sendmail.cf generated is correct - at least in
this area.
The relevant lines are:
# place to which unknown users should be forwarded
Kuser user -m -a<>
DLlocal:baduser
baduser exists as a user and the test command must be run as root. Ordinary
users are not allowed to run sendmail -bv.
selinux is disabled.
Wouldn't entries in mailertable/virtusertable affect the command line also??
The maillog (on the F22 box) says:
Dec 29 10:36:02 mustang sendmail[8371]: tBT062b7008371:
<garbage@xxxxxxxxxx>... User unknown
and the sender gets a bounce response.
The Centos box does the same.
