ASSP 2.5.5 - 16366 SSL Auth failures seem to be recording against address 0:0:0:0:0:0:0:0 and the incoming addresses are being looked up against this pattern, and rejecting for AUTH failures from different addresses. I don’t quite understand why the addresses are being presented in IPv6 mapped IPv4 format (yes I really am running both stacks, but each on different interfaces)
Anyway the net result is that some users are being rejected despite having 17-01-16 09:40:05 [Worker_3] [SSL-in] ::ffff:62.122.21.101 [SMTP Error] 521 ASSP.OA5.COM does not accept mail - closing transmission - too many previous AUTH errors from 0:0:0:0:0:0:0:0 17-01-16 09:43:20 [Worker_3] [SSL-in] ::ffff:170.84.97.125 [SMTP Error] 521 ASSP.OA5.COM does not accept mail - closing transmission - too many previous AUTH errors from 0:0:0:0:0:0:0:0 17-01-16 09:45:08 [Worker_6] [SSL-in] ::ffff:178.148.111.1 [SMTP Error] 521 ASSP.OA5.COM does not accept mail - closing transmission - too many previous AUTH errors from 0:0:0:0:0:0:0:0 17-01-16 10:10:27 [Worker_7] [SSL-in] ::ffff:182.48.75.68 [SMTP Error] 521 ASSP.OA5.COM does not accept mail - closing transmission - too many previous AUTH errors from 0:0:0:0:0:0:0:0 17-01-16 10:35:07 [Worker_4] [SSL-in] ::ffff:190.155.199.60 [SMTP Error] 521 ASSP.OA5.COM does not accept mail - closing transmission - too many previous AUTH errors from 0:0:0:0:0:0:0:0 Andrew Macpherson <and...@oa5.com> (Twitter @OA5dotCom) The Old Church, 22-24 Church St, Milnathort, KY13 9XH, GB Phone tel:+441577861848 GSM tel:+447899961797 LEGAL CLAIMER: Any claims made at this point in a message are completely invalid as they are presented after the information they attempt to assert rights over has been disclosed without prior caveat ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Assp-test mailing list Assp-test@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/assp-test
