Hello everyone.
As some of you told me, there were problems with Haifux' mailing lists recently, in particular with those using Google's mail services, who didn't get the mails at all. Others have seen delays. This has been solved now. This message will reach everyone (fingers crossed...). I'm sincerely sorry for the inconvenience, specially those of you who missed lectures because of this. Please keep an eye on our site, if you don't hear from us for a while. The root cause is that we moved server about a month ago, and it took some time to get the rDNS set up. This is done through a manual request from the service provider. Lesson learned: Don't switch server before the rDNS is set up, and don't start the transition near Christmas... On top of that, the new service provider supplies an IPv6 address. Hurray! Well, not. The mail server used the IPv6 address to contact Google's mail server, which refused to handle the messages, saying "Service unavailable". I suppose that the reason is that haifux.org has forward and reverse DNS entries for IPv4 only, so the mail server considers our MTA to be a massive spammer. I solved it by turning IPv6 off. Not politically correct, but is there any practical reason to support IPv6 these days? I suppose that the right thing is to set up IPv6 DNS records and possibly an SPF record. But I can't see the reason to bother. Thanks to Guy Edri for the crucial clue while sorting this out. Sorry again, Eli -- Web:http://www.billauer.co.il _______________________________________________ Haifux mailing list Haifux@haifux.org http://haifux.org/mailman/listinfo/haifux
