There is little traffic yet on IPv6, so it's not an issue yet.  I have my servers open on IPv6, but have no dns entries pointing to them yet.

Right now, if you put surgemail into ipv6 mode, your ipv4 rbl's won't work.  ChrisP is aware of this, but I don't think he has put out a new beta yet with a fix.

Lyle,

 

One of my hesitations for running IPv6 with Surgemail was lack of RBL support and the fact that spammers would adopt IPv6 just to get spam through because there aren’t as many checks in place. What RBL’s support IPv6 lookups that you are using? If I can get a working copy of Surgemail that does RBL lookups for IPv6 addresses and the RBL’s I’m querying support them, I think I’ll try flipping it on.

 

Thanks!

These 'errors' are not real errors, but display problems only. 

Drop to a command prompt at root(or sudo) and run:

netstat -apn | grep surgemail

And that should show surgemail listening to ipv6 addresses.

Also unless ChrisP has sent you a new binary, your rbl's won't work in ipv6 mode.  Surgemail was malforming the queries to rbl's when in ipv6 mode.  I brought this to his attention early last week, but have not heard if he has released a fixed beta for that bug yet.

I have been trying to get surgemail to use IPV6 as I have a router setup using mandriva linux 2010.

This is using a tunnel to Hurricane Electric for ipv6 and works well with my Apache web server on IPV6 but I can’t get it to work with Surgemail.

Surgemail is running on the same computer as the Router.

 

I am using SurgeMail Version 5.1c-1.      

 

With g_ipv6_enabled true this is what I get when starting Surgemail…

 

Startmail starting surgemail using configuration file /etc/surgemail.ini

Setting owner and mode for startmail binary, chown root:root, chmod 04775 startmail

StartMail: with ipv6, config setting=(true) 1

Starting surgemail as uid=0 gid=0 based on /usr/local/surgemail

Call execv (./surgemail)

MAIL Running - Home /usr/local/surgemail - log file is /usr/local/surgemail/mail.log

Detaching server process
