Cannot receive e-mails

Cannot receive e-mails

Hi, I'm testing my mail support@tikitakastore.com and It seems to send/receive e-mails from some accounts but not others. For example, whenever I try to recover a password from my account in some other website and I put support@tikitakastore.com it order to send the verification e-mail, I never get it.

I'm also testing sending mails from here https://putsmail.com/tests or https://www.mail-tester.com and I never get those mails either.

Thanks in advance,
Daniel
