Log in to webmail address issue

[#1]

Hi all, hope someone can help. (I expect this is easy and I just can't get it). I am trying to log into my webmail acount to delete old messages to stop the (you are over 75% emai usage).

Used to delete all my e-mails from the server by using my phone where i could see all the folders and files etc. But now I cant?

I can get into my default account, e.g (user name) "newtricks" but not the other e-mail accounts. What is the format to get into these. I have tried eg, "newtricks+oldtricks", "newtricks+oldtricks.plusnet.co.uk"

Also, is the password for each the e-mail password, or your plusnet password?

Many thanks for any help.

@texas The login format for secondary mailboxes is 'username+mailboxname', and the password associated with that mailbox.

Thanks, just got myself confused a bit. The password I was using was an old one!!
