Disabling startup check still checks for new email when starting.

I have disabled send and receive at startup but em client still checks for new emails when starting up.

The option doesn’t affect IMAP accounts for technical reasons related to how the synchronization works. The individual folders are still synchronized whenever you open them, so any access to the Inbox will still force the new messages to be downloaded.

You may switch the whole client offline using File -> Work offline in the menu (or by holding the CTRL key when starting eM Client).
