    and also also if i browser mail.varsa.gr it also loads ypsilandio.gr !!

    WHY?!

    It means that your server IP is blacklisted by Google.

    Basically they suggest using Postmaster Tools for more information, using SPF (you have that already), DKIM (can't tell), and DMARC (you don't have that), and making sure your email messages are formatted correctly.

    But if you send too many emails at once then you will still get in trouble, so if you do that a lot then you need to reevaluate how you do bulk emails. Perhaps by spreading the messages over time rather than trying to send all at once.

    I wouldn't be surprised if Postmaster Tools had something to help with that.
