Thanks for the link!

I checked it and findings were following:

SPF Record Check - no issues reported
DKIM - that i could only check for gmail and not outlook, according to that link...
DMARC
Only 1 founding: Policy Not Enabled DMARC Quarantine/Reject policy not enabled (mxtoolbox)
but this seems to be okay, as it just shows that there is not additional protections set up..?!

Thanks

    Hi,
    
    so this discussion just suggested to check blocked and safe senders list.
    
    This really can`t be the right solution. How come i can`t reply to travel agent who email me first time? (in addition to other examples i had.. ).

  Dear Raginho
  
  Is it possible if you could provide a screenshot of the error message?
