I use outlook to manage my emails. my outlook accounts all point to my btinternet.com service. about 6 months ago I started having issues wil sending emails to a gmail.com account. Receiving gmail.com emails was no problem. I would get an email administrator bounce back email saying it had failed both a SPF check and a DKIM check. However if I log onto my bt email system there is no problem with sending an email to a gmail.com email address. ANY IDEAS?:
