Re: [ilugd] Postfix sends all mails to SPAM
Dear all Hello, This is robin ladwal here. I am a beginner to the vast ocean of open source knowledge base. I have been wandering around various forums across the world. I went through so many discussions on various topics. I was so happy to know about delhi Linux community and mailing list. I would only like to say that we are only collecting pebbles on the sea shore and there is vast hidden world to be discovered. But guys its shattering that we guys are fighting just to prove each other wrong and to prove our supremacy. Mailing list Forums are not appreciated to prove your capabilities or supremacy. I agree that in India, Open Source and related topics are still at initial state and would need time to emerge as huge knowledge base. In this whole scenario, there would be some of our friends who have started early and have much knowledge and expertise then the novice. But the essence of open source says that elder help younger so as to gain the knowledge and legacy through mutual sharing selflessly. Ego nowhere supports sharing. Knowledge is eternal and an single entity. If we see in depth, Knowledge is what we know as god and worship. And there is nothing wrong in self testing and revaluation of our concepts and to accept our mistake if we find ourself wrong. Knowledge is a single entity and can not contradict itself. So please guys, i request you all to be polite and not bring our egos in between the sharing. We are here to learn and share. Lets create a better example of brotherliness and be together to discuss and solve our problems. I want to learn and so do we all want. Lets leave trivial issues and join our hands in the spirit of Open Source and Ubuntu(Not the Linux version but essence of word Ubuntu). Thanks Regards --- Robin Ladwal CEO Arahan Solutions (P) Ltd.

Re: [ilugd] Postfix sends all mails to SPAM
Hi Abhisekh, Please use mxtoolbox.com to check whether you server is open relay or not. Regards, Nishant Kashyap On Sun, Jun 20, 2010 at 11:54 AM, abhishek jain abhishek.netj...@gmail.comwrote: Oh, so if you're using the same domain name for sending emails, it is better to configure your postfix to act as smarthost and relay all mails through Gmail's SMTP. And also as others have mentioned already, check the PTR record, and IP address of your box being list in DNSBLs. The whole process of assuring your email is delivered reliably in recipient's inbox is quite fuzzy. For some guys, adding a PTR record is just enough, while for others who got blacklisted during beginning, they also need to get SPF[1], DKIM[2] setup to assure delivery of emails. @Abhishek: Ashish's is the most accurate response. There's no quick fix for this - if you already have a Gmail account, then you are much better of using Gmail's SMTP instead of your own, which you can configure in Postfix. Of course, you cannot set an arbitrary address in there. If you notice, there is a lot of change in the way mails are handled these days. For instance, Gmail relies on SPF and DKIM (Domain Keys Identified Mail), and still it can send your mail to Spam if your reputation has not been good. Yahoo on the other hand requires Domain Keys only (for which you've to use dk-filter/milter and not dkim-filter), and may require participation in its Feedback Loop. Hotmail requires you to have SPF Sender ID configured, AND, to ensure delivery you need to go through their JMRP (Junk Mail Reporting Program). And, goes without saying, PTR, not listed in DNSBL, having a correct 'helo' name, and some criteria as mentioned in CAN-SPAM Act are to be followed. You really have to spend some time doing this right, and you have to ensure that you maintain your reputation all times. All the best with your endeavor ;-) Thanks Vivek , Ashish and others. I had a server before and i had no such problems before, this problem arised when i moved to a new VPS provider, however the IPs etc as mentioned are not blacklisted or so, (checked from link provided above http://www.spamhaus.org/lookup.lasso . ). My guess is some configuration in postfix, as i never had to set SPF etc. before. As per the open relay thing, i am not sure how to check this, however i will take google help on this, The server is hosted on webmin control panel, can there be a simple setting there which can help me at this, thanks abhishek ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd -- Warm Regards, Nishant Prakash Kashyap ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd

For setting up SPF and DKIM both, you've to create a TXT records in your domain name's zone. Exact details you can figure out by searching the web. For DKIM, you also need to integrate your postfix MTA with dkim-milter (or whatever DKIM signing agent you find) to sign emails. And if you want to avoid all this hassle just relay via Google's MTA like I do :).

Sorry for the confusion, I mean to say configure postfix to relay all mails through Gmail's SMTP. There is no smarthost here.

Re: [ilugd] Postfix sends all mails to SPAM
Naresh, Get your basics right first. There are multiple reason for this and few are directly related to Postfix. If postfix is open relay, it hardly takes 2-3 days for the mail server to get blacklisted. By the ways, as other other has already mentioned, below are the reason that can cause the issue. 1. Blacklisting in RBL/DNSBLs Server (use robtex.com to check) 2. Absence of PTR Record. 3. Wrong SMTP Banner. 4. Subnet may be in a pool which has mail server as open relay server (very common). 5. SPF Record. 6. The Server may be a real source of SPAM (quite possible that you are really spamming). 7. Proper CNAME if A Record is something else. 8. Opt In and Opt Out option for Subscribers if you are using the mail server for Email Marketing. 9. For complete consultancy and solution, user needs to pay me [Commercial].

Great, please explain these items being the reasons for being dumped as SPAM - Blacklisting in RBL/DNSBLs Server (why did it end up in spam was the question to begin with, chicken or the egg first.) Wrong SMTP Banner. What significance does it have except legal. SPF Record (20% utilization as of 2008). The Server may be a real source of SPAM (how do you determine this in absence of other facts mentioned.) Proper CNAME if A Record is something else. Whose CNAME and A records, please elaborate. Opt In and Opt Out options. - Really? I get dumped in SPAM because SMTP server didn't find Opt-in, Opt-out in my email body? Now that's scary I think. How does SMTP server determine if my email was a marketing email or not. Your email didn't go in SPAM either though there was no Opt-out mentioned. Others are pretty obvious. Correct configuration of Postfix assumes that it is not open relay, which mostly are not by default. Pay you, yeah that's the reason. --Naresh ___ Ilugd mailing list Ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd
