As a continuation to my previous entry about IO-Socket-INET6, I'd like to note that I received several responses to my message about resuming its maintenance. Eventually, the original author replied too and agreed to give me a co-maintainer status on PAUSE.
So I wrapped things up and uploaded a new version of IO-Socket-INET6 to the CPAN, and it indeed got indexed properly. I already received several error reports from CPAN testers, but I'm not sure I can do anything about them, because the end-hosts don't seem to support IPv6 well.
Next I'd like to increase the module's kwalitee and to look at bug reports.
Now I can be proud that there's now a small part of me in SpamAssassin.
