External Konto with IMAP

Hello,

I would like to link to my zoho mail account an estern email account with IMAP.

Here are the access:
Server : imap.provider.de / Port 143
Server SSL : imap.provider.de / port 993

It is working with POP but not with IMAP (Error : Zoho Mail can only use the port: 110, 995).

Is there a solution to do this?

Goal: I would like to be able to see, in Zoho and in the provider email interface, the "inbox" content for example.

Thanks and regards,
Mat
