problem with receiving emails from certain addresses

problem with receiving emails from certain addresses

Hi,

I assume that a lot of mails to me was undelivered without any error messages or returned emails.

Example:
emails from domain avalon24.pl  are not delivered to my mailbox ml@lkavalon.com hosted via zoho.com. Can you check it?

BR,
Miroslaw Liminowicz
