Hi, (Apparently I didn’t reply to the list the first time, sorry for the duplicate.)
Thanks for the detailed reply. > * both are not identical > * the first one is broken - you include yourself > * A/MX turned out error prone > * hence i recommend using ipv4 notation (-all versus ~all non-strict) I fixed that isogram.nl. 300 IN TXT "v=spf1 ip4:178.62.242.224 -all” infinitesimal.nl. 300 IN TXT "v=spf1 ip4:178.62.242.224 -all" > * frankly - normally MX priority starts with 10 not 1 > * i would also recommend a *hostname* instead just the domain > * smtp_helo_name should match the hostname / PTR - i doubt the > machine is called just like the domain (default si local hostname) > * so i would set all 3 to "mail.infinitesimal.nl" and hence the "mail" > it may be better handeled by spamfilters in case of PTR checks and > avoid false positives Also fixed these problems. The machine was in fact called infinitesimal.nl, but I renamed it to www.infinitesimal.nl (my SSL certificate doesn’t cover mail.infinitesimal.nl). I also fixed the MX records, and ran both domains through mxtoolbox.com again. isogram.nl. 300 IN MX 10 www.infinitesimal.nl. infinitesimal.nl. 300 IN MX 10 www.infinitesimal.nl. 224.242.62.178.in-addr.arpa. 3600 IN PTR www.infinitesimal.nl. Mails from @isogram.nl still get consistently spam filtered, however, mail from @infinitesimal.nl is no longer marked as spam. -- - Tiemo
