Question How can i speed up IMAP Webmail?

[Jan Freymuth]

Hi Plesk Team and others,

i am migrating ~15.000 Mails via Outlook (Drag and Drop) to my PLESK System running on a windows server 2019.

Plesk (MailEnable) is super super slow. It only sync around 3Mails/second. So i have to wait around 1-2hours.

I tested this with other big e-mail provider. And there i can upload 15.000 Emails in 2-3 minutes. So whats wrong with plesk mailenable system and IMAP?

Regards
Jan

I am using latest plesk version. 18.0.20
Windows Server 2019 in german data center. (10GB/s) - (i9, 128 GB Ram, nvme ssd)
