Hello. I have an application that sends emails via POP3. About 500 emails leave the server in 10 seconds.

I converted it to anonymous sending. Now I have one email going out in a minute.

What can the delay be caused by and how to fix it ?

    I converted it to anonymous sending.

    You could use Telnet command to send emails? You can also check the mail flow for it with Message Tracking Log: 

    Get-TransportService | Get-MessageTrackingLog -Recipients user@domain.com -MessageSubject "subject" -Start 10/17/2022 -End 10/19/2022
