Setup your reverse IPv6 records correctly or tell Exim not to send via IPv6.

Add disable_ipv6=true to /etc/exim4/exim4.conf.template

And add ipv6 address to SPF record.

Actually, if he add reverse DNS for ipv6, and add ipv6 to SPF, he does not have to turn off ipv6 on Exim.

I suggest the option of dpeca. When the IPV6 support is coming in the next days, weeks or months you don't need to search why IPV6 mail isn't working when you disable it.
