Random Email Missing for specific domians

Random Email Missing for specific domians

Our mail service randomly fails to receive emails.
When certain domains proactively send emails, our sales team reports that they haven’t received those messages from clients.

This creates a financial risk for us in certain cases.

We’ve already submitted a ticket, but the engineers seem very busy.
Has anyone else experienced random missing emails?

I can confirm that I didn’t find these emails in the quarantine, and I’ve also disabled system-level spam filtering.

I suspect there might be some network-related issues with the mail service.

This significantly lowers our trust in the service.

Previously, our sales team mentioned that even free Gmail is more stable than this paid subscription.

My ticket is 114956209

Currently the Lead Section is missing "Add contact" feature which is available in "Accounts". When you know that a particular lead can have multiple contacts, why was this feature not included. Now we have to miss out other contacts or enter them somewhere in the description.!!! this is bad.
