Imap config on webmail port 993

Hi everyone.
I've two different account in zoho and i want to read both account from a single interface.
I'm trying to configure the second account imap in the first webmail.
The only problem that i'm facing is that the config seems to not support the 993 port.
How i can configure a zoho imap email without the 993 port??

Thank you
Tommaso
