Resolve the issue with email blocking

Budget: 1000 UAH Deadline: 1 day

Good evening,

I am a Linux administrator with over 10 years of experience, working in a hosting company. I have extensive experience in email configuration and delivery. Judging by your screenshots, there could be several options: either the recipient's mailbox is full, the mail server rejected your message due to spam filter settings, the mail server is unavailable, or your email has been blacklisted. More details need to be looked at in the mail server logs.
