Re: [courier-users] Classless reverse dns and mail delivery

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. Thanks.

Re: [courier-users] Setting a bounce address
Thanks for your response. I'll try to use a python filter quota to avoid the problem I have. --- El jue 3-sep-09, Sam Varshavchik mr...@courier-mta.com escribió: De: Sam Varshavchik mr...@courier-mta.com Asunto: Re: [courier-users] Setting a bounce address A: courier-list courier-users@lists.sourceforge.net Fecha: jueves, 3 septiembre, 2009, 7:32 pm Carlos Lopez writes: Hi Sam, thanks for the explanation, but. When this message appears: id=0020600B.4A9FDAE3.19C5,from=,addr=u...@yahoo.com: 250 Backscatter bounce dropped. Sep 3 09:04:03 localhost courieresmtp: id=0020600B.4A9FDAE3.19C5,from=,addr=u...@yahoo.com,success: delivered: backscatter bounce dropped Does that error come from courier modules or from the @yahoo.com server? From Courier. See my last message. If it is from courier, how to do in order to inform u...@yahoo.com (or any domain) that his mail had failed? The bounce is what informs the sender of a delivery failure. See my last message for more information. Now, Well, messages should not be queueing up. As you've seen yourself, when Courier holds a message to a recipient in the queue, because of a temporary delivery failure, it stops accepting any more mail to the same recipient. So, you should not have more than one or two messages in the queue to the same recipient. As I already stated t...@mydomain.com's maildirsize is: 52428800S 52429312 45 This has nothing to do with the mail queue. from many days ago, but sometimes courier accepts email to t...@mydomain user and it queues again. Does courier have a counter or something similar, that counts the times that and error of a failed delivey and reset it after a period of time? See the explanation at the beginning of the courier(8) man page. Why courier accept and queues it, if t...@mydomain.com is already overquota, Wouldn't be better to just block delivey from Because it is not know where mail addressed to t...@mydomain.com goes, until an actual delivery attempt gets made. The recipient's .courier file may, for example, specify that the recipient's mail is to be forwarded elsewhere, or be delivered to some non-default mailbox location. Therefore, when mail gets accepted for a given recipient, the mail's ultimate destination is not know. -Adjunto en línea a continuación- -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[courier-users] sendmsg() conflict
Sam, I thought this was fixed a few years ago, but it looks like this
bug is still present in Courier 0.62.2.
sendmsg() is a standard libc function, and is also the name of a
function in imap/outbox.c. Libraries which attempt to use libc's
sendmsg, such as libselinux and libfam, may end up calling imapd's
sendmsg instead, which causes imapd to segfault. Can you please rename
this function?
