This hack is to enable Virtualmin to display and edit ipv6 SPF records.
First locate where the webmin install is located then open the file "virtual-server/edit_spf.cgi"
On line 23
# Extra a, mx, ip4
$edspf = $spf || $defspf;
foreach $t ('a', 'mx', 'ip4', 'include') {
print &ui_table_row(&hlink($text{'spf_'.$t}, 'spf_'.$t),
&ui_textarea('extra_'.$t,
join("\n", @{$edspf->{$t.':'}}), 3, 40));
}
Change to
# Extra a, mx, ip4 and ip6
$edspf = $spf || $defspf;
foreach $t ('a', 'mx', 'ip4', 'ip6', 'include') {
print &ui_table_row(&hlink($text{'spf_'.$t}, 'spf_'.$t),
&ui_textarea('extra_'.$t,
join("\n", @{$edspf->{$t.':'}}), 3, 40));
}
Close file.
Open "virtual-server/lang/en"
add the line
setup_eip6=Missing or invalid IPv6 address
close the file.
Open "virtual-server/save_spf.cgi"
Find
elsif ($a eq "ip4") {
# Must be a valid IP or IP/cidr or IP/mask
&check_ipaddress($v) ||
($v =~ /^([0-9\.]+)\/(\d+)$/ &&
$2 > 0 && $2 <= 32 &&
&check_ipaddress("$1")) ||
($v =~ /^([0-9\.]+)\/([0-9\.]+)$/ &&
&check_ipaddress("$1") &&
&check_ipaddress("$2")) ||
&error(&text('spf_e'.$t, $v));
}
Add after
elsif ($a eq "ip6") {
# Must be a valid IP or IP/cidr or IP/mask
#This needs to be completed
}
Close file.
Make the file "virtual-server/help/spf_ip6.html" and open it paste
<header>Allowed sender IP addresses</header>
This field is similar to <b>Allowed sender hostnames</b>, but is for entering
IP addresses of systems that also send email from this domain, and do not
have hostnames. <p>
<footer>
Close file
Open "virtual-server/modify-dns.pl"
go to line 80
you should see
elsif ($a =~ /^--spf-add-(a|mx|ip4)$/) {
$add = shift(@ARGV);
$type = $1;
$add =~ /^[a-z0-9\.\-\_]+$/ ||
&usage("$a must be followed by a hostname or IP address");
push(@{$add{$type}}, $add);
}
elsif ($a =~ /^--spf-remove-(a|mx|ip4)$/) {
$rem = shift(@ARGV);
$type = $1;
$rem =~ /^[a-z0-9\.\-\_]+$/ ||
&usage("$a must be followed by a hostname or IP address");
push(@{$rem{$type}}, $rem);
}
change this to
elsif ($a =~ /^--spf-add-(a|mx|ip4|ip6)$/) {
$add = shift(@ARGV);
$type = $1;
$add =~ /^[a-z0-9\.\-\_]+$/ ||
&usage("$a must be followed by a hostname or IP address");
push(@{$add{$type}}, $add);
}
elsif ($a =~ /^--spf-remove-(a|mx|ip4|ip6)$/) {
$rem = shift(@ARGV);
$type = $1;
$rem =~ /^[a-z0-9\.\-\_]+$/ ||
&usage("$a must be followed by a hostname or IP address");
push(@{$rem{$type}}, $rem);
}
I think that's all I changed.
Now when you look at the DNS Options you should see a section for IPv6 address's.
Also you can now use modify-dns.pl to add ip6 SPF records.
Example
virtual-server/modify-dns.pl --all-domains --spf-add-ip6 2a90:490:190:4fff::ffff
Thanks for this patch / suggestion. I will incorporate and equivalent change into the next Virtualmin release.

Cool. Like I wrote in one of the comments and meant to mention. This does not check the ipv6 address is in a real address so no error checking. but you know what to fix for that better then me :)
I only wrote this due to Google stepping up there anti spam on ipv6 recently and mail was not SPF passing :(
Yes, I added a check to ensure that the IPv6 address is in the correct format.

I look forward to seeing this soon ish LOL
