MX pointers and DKIM didn't have anything in common with rspamd as software for antispam. MX pointers anyway you have to configure to point to your mailserver, but rspamd, may reside on same server (localhost) or on remote server, but it doesn't matter for MX pointer. — Reply to this email directly, view it on GitHub <https://gist.github.com/mdpuma/f1c347091717240276fcb0bab737f7ec#gistcomment-4591832> or unsubscribe <https://github.com/notifications/unsubscribe-auth/AH77JOZYBX2ATWTJ4GSCE33XKAIS5BFKMF2HI4TJMJ2XIZLTSKBKK5TBNR2WLJDHNFZXJJDOMFWWLK3UNBZGKYLEL52HS4DFQKSXMYLMOVS2I5DSOVS2I3TBNVS3W5DIOJSWCZC7OBQXE5DJMNUXAYLOORPWCY3UNF3GS5DZVRZXKYTKMVRXIX3UPFYGLK2HNFZXIQ3PNVWWK3TUUZ2G64DJMNZZDAVEOR4XAZNEM5UXG5FFOZQWY5LFVA2DEMZQGU4DAMVHORZGSZ3HMVZKMY3SMVQXIZI> .
