POP3 client freeze during connection to server that don't recognize CAPA command


I have problem during connection to server that don’t implement POP3 extensions (CAPA command)

+OK Hello, this is ***** server unknown.
-ERR Unknown command

In that case communication freeze and after timeout exception is thrown. Diagnostic log is attached. Could you provide me any advice how to connect to this type of server? It is public server so I could provide you connection information in private message.
Thanks in advance

Hi Michal,

Thank you for writing to Aspose support team.

Could you please provide more details about the server you are connecting to? I have tested this scenario by connecting to a POP3 server using the latest version of Aspose.Email for .NET 4.8.0 and it works fine. I would request you to please provide us with a test account credentials in order to test this issue at our end and assist you further.

I can confirm that in last version (4.8.0) is problem fixed. We used old library.
