[courier-users] set MAXPERIP in smtpaccess
Is it possible to use an smtpaccess file to set different MAXPERC and MAXPERIP values from esmptd for certain machines? The defaults are '5' each, which is reasonable IMHO. But I'd like to increase the values for certain internal machines which periodically send TONS of mailing list messages at a time. I already had 192.168.100.12TABallow,RELAYCLIENT,BOFHCHECKDNS=0 in smtpaccess/default, so I changed it to 192.168.100.12TABallow,RELAYCLIENT,BOFHCHECKDNS=0,MAXPERC=500,MAXPERIP=500 and ran makesmtpaccess But I still get errors like courieresmtpd: Maximum connection limit reached for :::192.168.100.12 TIA Jeff Jansen -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Re: [courier-users] Setting a bounce address
Thanks Sam for you fast response. What I was trying to explaing is as follow: First I got a test account named t...@mydomain.com, on courier-mta server I have almost 100 accounts which send and receive tons of emails every day, they are u...@mydomain.com. The quota assigned are 50MB and the max message size is 10MB. Now, on these days the company is sending almost most of the employees to vacation and almost most of the email accounts are getting over quota. I've been trying to figure out how to avoid courier-mta filling up the queues since I got almost 400 emails sent to internal accounts from servers like google, hotmail, yahoo and other email servers. I read that courier does not bounce back messages to over quota accounts, It rather send them to the queue spool dir and try to send them after a period of time, but afte many failures courier-mta server should send back a Failure Delivey to the outer server (server like yahoo, google or hotmail, etc), but when It sends it the outer server reply with an error message like Bounce back drop, if the failed message is not received by the sender (yahoo, google or any other) then none of the parties would now what happening with their messages. the file maildirsize for t...@mydomain.com got this: 52428800S 52429312 45 Technically speaking, this is what I got from courier logs: 1- First the outer server tries to send an email to t...@mydomain.com courier queue the message: Sep 3 08:40:20 localhost courierd: newmsg,id=00206007.4A9FD553.11C2: dns; web45115.mail.sp1.yahoo.com ([:::68.180.197.175]) Sep 3 08:40:20 localhost courierd: started,id=00206007.4A9FD553.11C2,from=u...@yahoo.com,module=local,host=t...@mydomain.com!!500!500!/dominio/mydomain.com/correo/test!!52428800S,addr=t...@mydomain.com Sep 3 08:40:20 localhost courierd: Waiting. shutdown time=none, wakeup time=Thu Sep 3 08:50:17 2009, queuedelivering=3, inprogress=1 Sep 3 08:40:20 localhost courierlocal: id=00206007.4A9FD553.11C2,from=u...@yahoo.com,addr=t...@mydomain.com: maildrop: maildir over quota.

[courier-users] Classless reverse dns and mail delivery
Hi Sorry if this is slightly off-topic. For the first time I've had to deal with classless reverse dns for a /25 subnet assigned to me. Thus, I've asked my IP provider to delgate rdns for the entire /25 to my dns servers. This is done in a way such that a reverse lookup looks a little different than normal by introducing an extra CNAME lookup step (see example below) and I'm simply wondering if I could run into problems with certain smtp servers when delivering mail to them from my courier server (slash.sentinel.dk). frede...@fda-lenny:~$ host 95.128.25.121 121.25.128.95.in-addr.arpa is an alias for 121.0.25.128.95.in-addr.arpa. 121.0.25.128.95.in-addr.arpa domain name pointer slash.sentinel.dk. frede...@fda-lenny:~$ dig -x 95.128.25.121 ; DiG 9.5.1-P3 -x 95.128.25.121 ;; global options: printcmd ;; Got answer: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 49385 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 0 ;; QUESTION SECTION: ;121.25.128.95.in-addr.arpa.IN PTR ;; ANSWER SECTION: 121.25.128.95.in-addr.arpa. 86394 INCNAME 121.0.25.128.95.in-addr.arpa. 121.0.25.128.95.in-addr.arpa. 10794 IN PTR slash.sentinel.dk. ;; AUTHORITY SECTION: 0.25.128.95.in-addr.arpa. 4918 IN NS ns01.sifira-ums.dk. 0.25.128.95.in-addr.arpa. 4918 IN NS ns02.sifira-ums.dk. ;; Query time: 0 msec ;; SERVER: 192.168.1.33#53(192.168.1.33) ;; WHEN: Thu Sep 3 16:34:37 2009 ;; MSG SIZE rcvd: 144 Best regards, Frederik Dannemare -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 Good afternoon, This is done in a way such that a reverse lookup looks a little different than normal by introducing an extra CNAME lookup step (see example below) and I'm simply wondering if I could run into problems with certain smtp servers when delivering mail to them from my courier server (slash.sentinel.dk). You should have no problems as long as the resolver used by the mail server you're delivering to handles it properly. To my knowledge, all of them do. A cname is a perfectly reasonable response to a request for a ptr, and should just cause the resolver to restart the lookup with the name specified in the cname response. It results in some extra overhead, but that's a problem any time you use cname records. - -- Stress (N): The condition that occurs when ones mind overrides the body's natural desire to reach out and slap the hell out of someone who desperately deserves it.
