Mail from IPv6 sources

Post by kamk » Thu Mar 26, 2015 3:35 am

When there's incoming mail from IPv6 address I see in the mail.log:

postfix/smtpd[29844]: connect from gmmr1.centrum.cz[2a00:da80:0:502::2]
magicspam-plesk[2171]: lm_dns.c:307 ERROR lm_inet_addr(): Invalid argument
magicspam-plesk[2171]: lm_dns.c:307 ERROR lm_inet_addr(): Invalid argument
magicspam-plesk[2171]: ../blockmaps/lookup.c:130 ERROR lookupMaps(): Invalid argument : invalid ip address

Hello Kamk,

Thank you for your post. Currently MagicSpam does not support IPv6 and this is the reason you are seeing these errors. We have now brought this up with our development team though and they will be working on a patch to suppress these errors. Please note that MagicSpam will not be rejecting these messages though, so you don't need to worry about lost mail.

IPv6 ant-spam is an interesting topic though and there is much discussion surrounding different methods to handle the problem. One of the biggest problems is that because the IP space is so large, reputation lists become very difficult to maintain and very cumbersome (searching and storage) due to their size on disk. As mail in IPv6 becomes more popular, you can be sure to see MagicSpam moving to react to this space, but for the time being the answers are still not completely clear.

Thank you again for you post!
