Error Connecting OnlyOffice to MailServer - Unable to Retrieve Hostname

[lundaoke]

Hello,

I've encountered an issue while trying to connect OnlyOffice to a MailServer. The connection process fails with an error indicating that the hostname cannot be retrieved. Below are the details of the error log:

log:
2023-11-23 07:25:03,016 ERROR [128] localhost - ASC.Api.Mail - Error: Unable to retrieve hostname System.Exception: Error: Unable to retrieve hostname
at ASC.Api.Mail.MailApi.GetHostname(String connectionString, String ip)
at ASC.Api.Mail.MailApi.ConnectMailServer(String ip, String sqlip, String database, String user, String password)

This issue occurs when attempting to establish a connection between OnlyOffice and our MailServer.
The error seems to originate from within the ASC.Api.Mail component.
It specifically fails at retrieving the hostname, as indicated in the error message.
Attempts to Resolve:

I have checked the network settings and DNS configurations, but everything seems to be in order.
The MailServer settings have been verified and are correctly configured.
Request:

Any insights or suggestions on what might be causing this issue would be greatly appreciated.
Is there a specific configuration or setup step that I might be missing?
Thank you for your assistance.
