Hi, when a user tries to contact me with a yahoo. * Email, Gmail replies that it cannot accept an email from a XXX.net domain in the name of Yahoo.
This is a serious problem because I am not getting the contacts.
I enclose the error below.

I have not found a solution. Anyone have any ideas?
Thank you.

to = <XXXX@gmail.com>, relay = aspmx.l.google.com [2a00: 1450: 400c: c0a :: 1b]: 25, delay = 0.44, delays = 0.1 / 0 / 0.16 / 0.17, dsn = 5.7.26, status = bounced (host aspmx.l.google.com [2a00: 1450: 400c: c0a :: 1b] said: 550-5.7.26 Unauthenticated email from yahoo.com is not accepted due to domain's 550-5.7 .26 DMARC policy.

There's not going to be anything you can do about it. Yahoo has set up it's mail policy and instructs mail servers to reject email @yahoo.com emails if they don't come from a yahoo.com IP address.

XenForo is effectively spoofing the From header to come from the user. The right way to do it from XenForo's standpoint is to have the contact email come from the site itself, and instead use the Reply-To header. While it's the intended way that XenForo works, it's seems like a borderline bug because it can cause undeliverable emails (as you see).

I ended up making a bug report here: https://xenforo.com/community/threa...-xenforo-due-to-from-address-spoofing.208998/

Actually, looks like there is something you can do about it. Check your Options -> Email options -> Sender info in from header on contact emails option (under advanced settings). It's off by default, but maybe it got turned on?
