Emclint does not work with new email

Hello,
Last week our company server and email has been changed.
I am trying to set up this new email and use with my EMCLIENT but i get “…com: Connecting to …com failed。
[SMTP An attempt to connect to …com failed. This could be caused by temporary server unavailability or incorrect settings. Do you want to check the settings?”

When i log in with same settings in foxmail (a chinese email client, ) it works fine.
I use 9.2.2307 version.

Thank you.
