Send email via IPv6 in cpanel v86
If anyone has any information that would be great. I have contacted Bluehost, Hostgator, Liquid Web and Hostwinds (each one hosts a VPS of mine) and they seem to be all confused as me. I want to send email via my ipv6 address. I have a VPS with 1 IPv4 and 1 IPv6. I added the domain: IPv6 entry in the /etc/domainips, restarted exim, changed the WHM->Exim Configuration Manager->Basic Editor->Reference /etc/mailips for custom IP on outgoing SMTP connections to "ON" yet emails still send from IPv4 address.

Hello, One thing I want to stress is that not all servers support IPv6 so forcing just IPv6 would be a terrible idea if you're sending mail all over the place. cPanel's Exim favors IPv4 over IPv6 and forcing the use of an IPv6 address is not possible with cPanel's exim implementation. Information on this can be found here: I am aware that the documentation here: indicates by telling you how to configure this with IPv6 that it will send with the IPv6 address but it is incorrect and there is currently CPANEL-7173 open for this. 0 -
So far from this scratch VPS i have assigned my IPv6 to the primary cpanel account/domain in WHM, setup my AAAA and SPF for the IPv6. Manually edited the exim.conf file remote_smtp (transport) section (interface line only) remote_smtp: driver = smtp interface = <; IPV6RREMOVED (the <; is needed to escape the colons) ..... changed the /etc/mailhelo from *:123.hostname.com to IPV6RREMOVED:123.hostname.com The sender IP shows ::1 instead of my IPv4 that's also on my VPS (I was given 1 IPv4 and 1 IPv6) Any other help would be greatful thank you community members 0 -
You can now use IPv6 for outgoing mail with Exim. I tested and confirmed on cPanel 92.0.11 See-> Can you change the Exim outgoing IPv4 address to an IPv6 address? 0 -
@executorbrandon Are you able to route your outgoing emails from IPv6? Can you confirm this? -2
