I got the doc from a machine running sendmail-8.10.2. What version do you run and what does your access file look like? Another thing is that the feature blacklist_recipients may not be enabled in your sendmail file. You can always check on that by looking at your /etc/mail/linux.mc to see whether FEATURE(`blacklist_recipients') is commented out and if it is you can uncomment it by removing the dnl at the beginning of the line. When you finish that you should rebuild the sendmail.cf file using the command: m4 linux.mc > /etc/sendmail.cf to recreate the sendmail.cf file. Then should see some info about blacklist_reciepients in the sendmail.cf file. The rest should be easy. You can then enter something like; username@ 550 Mailbox Full in the access file, make the database using makemap hash, restart sendmail and try to send mail to that particular user. In your log file you should see something like this: Apr 2 12:20:46 pop sendmail[13613]: f329KkQ13613: from=<root@spice.eahd.or.ug>, size=401, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, relay=[192.168.1.10] Apr 2 12:20:46 pop sendmail[13613]: f329KkQ13613: ruleset=check_rcpt, arg1=<begj@pop.eahd.or.ug>, relay=[192.168.1.10], reject=550 5.0.0 <begj@pop.eahd.or.ug>... Mailbox disabled And in this case you can see that the mail is rejected immediately after the banned reciepient is mentioned (which is quite noticable when you telnet to the sendmail port and execute the commands ehlo, mail from, rcpt to...) which I think is exactly what you wanted. -- Regards, ----------------------------Joseph Begumisa-------------------------------- Uganda OnLine/East African Help Desk Unix Systems Administrator ----------------------------begj@eahd.or.ug-------------------------------- On Mon, 2 Apr 2001, avl wrote: > > Hello! > > > domains, or addresses in your domain which should not receive mail: > > > > badlocaluser@ 550 Mailbox disabled for this username > > host.mydomain.com 550 That host does not accept mail > > user@otherhost.mydomain.com 550 Mailbox disabled for this recipient > > In the README of my distribution of sendmail the sign '@' is missed ... > Anyway, it doesn't work unless I specify the full user's address : > localuser1@my.domain.com > Is there anything wrong with my domain and sendmail configuration ... ? > > And, though it rejects mail now, when I specify full address, it rejects > it only after it gets all its body (may be very large).. > It would be better to reject the unwanted email immediately , without the > need to transfer all it's body... > > > Best regards, > Andrei > > > - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
