XF 2.0 Gmail users not receiving emails

[Kangy]

I have searched and tried some of the suggestions already. I changed the SMTP from localhost to my server. I've confirmed from my cpanel that the messages are being delivered. Checked mxtoolbox for blacklists and my domain is not on any of them. I've registered with Google postmaster tools. I'm getting all notification emails.

There is a trend with Gmail users not receiving the confirmation email. I've got 10 pending registrations right now and they were all Gmail and they all say they haven't received it. A couple of them have claim to have searched and double checked spam and everywhere but they're not getting the email.

It doesn't sound like a xenforo issue. I figured I'd ask for help here in case someone else has experienced this

Deliverability is a bit of an art and things such as sending IP reputation has a big impact.

You mentioned you use SMTP to send emails? Is that an external SMTP server? Have you checked the IP address of the SMTP server against blacklists?

It could be that the sending reputation of the SMTP server IP address is low, which is causing your emails to be penalised.
