Email filtering into folders

[#1]

Finally getting my email back to PlusNet having used another service for a while...
What I would like to do is to be able to set a rule that says ‘If an email comes to me at abc@123.plus.com it will be put in a folder called abc’, while ‘if an email gets sent to me at def@123.plus.com it goes into a folder I have named def’ – is that possible within the webmail programme?
Many thanks

Webmail does not offer email filter rules, though you could do that using IMAP and rules set up in your own email client such as Thunderbird.
The alternative is to set up mailboxes for 'abc' and 'def' in Manage My Mail logging into the separate mailboxes with usernames '123+abc' and '123+def' (and the appropriate mailbox passwords) to read the messages.

If you use SquirrelMail you can set it to colour the emails differently...
