[Mailman-Users] Trouble with mailman external responses
Hello, I'm trying to set up mailman along with postfix to be able to create my own mailllists at home.. I use a dyndns, which I'd like to use for the mail list URL (is that possible??) - boffman.mine.nu. It seems to work fine, I can send mail between users on the machine, locally.. I can send mail from a local user to an external mail.. And the other way around. I can also subscribe to a list, locally, and get the confirmation.. But this is what fails externally. That is, if I send a mail to some [EMAIL PROTECTED] from an external mail account, something goes wrong.. For some reason it uses the result from gethostname()(?) as address in the mail ( blahblah.bredband.comhem.se) instead of boffman.mine.nu. I have a log extract from the mail log over this scenario, here: http://rafb.net/p/WRvuTL64.html As I understand, something (wrong) happens at line 11.. There it uses @ c83-255-126-145.bredband.comhem.se for the first time.. Which I do not want.. And after that, it uses that as from-address in the relay.. Or something. I can't figure out what happens.. I just hope it's some simple configuration detail that I've missed. Any tips are highly apprecciated !! -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=showamp;file=faq01.027.htp

I just want to add that you may have problems trying to run Mailman from a server with a dynamic IP. Earthlink.net for one will not accept your mail. The same is true for some smaller ISPs. They don't like IPs with a 'generic' rDNS. Depending on exactly which ISPs are used by your list members, you may not be able to send mail to all of them unless you have a fixed IP, and rDNS for the IP that points back to your domain. I had the same issue with sending mail directly from my home network. I already had a static IP, but it had a generic name. I had to register my own domain and get the ISP to set rDNS for my IP to point to my domain. -- Mark Sapiro [EMAIL PROTECTED] The highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

Earthlink.net for one will not accept your mail. The same is true for some smaller ISPs. They don't like IPs with a 'generic' rDNS. The biggest problem I had when I was doing a mailman list on my home server was that many sites would refuse email from IPs that were on their RBLs list of dynamic IPs. Yes, some of them look for a valid rDNS, but 99.99% of them were perfectly happy with an rDNS of 74-202-84-132.static.twtelecom.net rather than list.xcski.com. I tried to get around that by sending my outgoing mail through my ISP's outgoing mail server (using Postfix's relayhost = [smtp-server.rochester.rr.com]), but then my ISP wouuld decide I'd sent enough mail for that day and block me for 24 hours.

Virtually all of the spam that gets through the various filters on my box comes from big-service dynamic IP's right here in the US. Right now, I'm trying to home in on some of this spam, and am operating under the assumption that I've got two or three users with infected Microsoft systems sending out port 25 mail without their knowledge. I've pinned down a couple of others. These users haven't got the foggiest notion that there is anything wrong, what is wrong, why it is wrong, or what to do about it, and that seems to be a common affliction among consumer users with always-on internet connectivity. My own site has two IP's, with their own identities separate from my upstream feed, with reverse lookups properly configured, and no port blocking either way. It took some time, discussion, and a couple of very serious technical interviews with their people before they agreed to that. They consider me a commercial site with competent on-site administration, and terms and conditions which are quite different from consumer sites. I'd really call a sendmail receiving site that blocks dynamic IP mail as misconfigured, when virtually all of the mail coming from such IP's is spam.

Hi Hank, I don't disagree, except to point out that no-reverse-dns dynamic IP (or clueless owner :). I'm still trying to get my ISP to provide reverse-dns for my static IP address, for which I pay $19.95/mo extra. I don't have many other options except to move to a CoLo, which I'd rather not do. I recognize that there's no good way for an MTA to determine what's truly a dynamic IP address, and that for the money I'm spending, my ISP really should give me a way to set up my reverse.

On the python.org mail system, we do not accept e-mail from sites that don't have proper working reverse DNS set up for their IP address. However, we do not refuse connections from networks that are known to be within dynamic IP address space from major providers -- some of our own key people (like Barry) use dynamic IP address space, and we wouldn't want to reject their connections or connections from anyone else doing the same. So long as those addresses have proper reverse DNS set up for them, and they're not on one of the very conservative RBLs that we use, then they should be fine. IMO, this is a reasonable balance to strike. Most everything else we do is done within SpamBayes, which is a Bayesian anti-spam classification system written in Python, and maintained by various well-known people in the Python community (see http://sourceforge.net/projects/spambayes and http://mail.python.org/mailman/listinfo/spambayes). In this respect, we eat our own dog food, and run the same anti-spam processing system on our own machines as we provide for the benefit of the larger anti-spam community. -- Brad Knowles [EMAIL PROTECTED], Consultant Author LinkedIn Profile: http://tinyurl.com/y8kpxu Slides from Invited Talks: http://tinyurl.com/tj6q4 -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=showamp;file=faq01.027.htp
