login details help

[szofar]

sorry if this is in wrong post

i have login details saved on the visa4uk site for about 2 years. Every time i login the username and password is saved.

now i have submitted a application with these login details the problem is that i dont have access to the email address which is my username.
after submission it stated that the application and biometric form is also emailed to the username email address. Now that is not a problem because i have printed them off. The real problem is that any emails from the ECO or visa services will be sent this email address??

can anyone confirm if any contact is sent to my login emails address or the email address given on the application from???
If it is sent to my login email how can i ask not to send any correspondence to this email
