You can access your Network Solutions mailbox through the Web using Webmail , or through your favorite email software client via POP or IMAP.
Instead of logging into the Account Manager each time to check your webmaill, you can simply type mail. domain.com in your browser, where domain.com is your domain. For example, if you own the domain networksolutions.com, then you would type mail. networksolutions.com in your browser to access the login page.
Please help
Thanks

I didn't find the right solution from the Internet.
