For combating spam there's a few things I can suggest. If the spam is going to a specific address that you don't use then you can use the Manage My Mail tool on the portal to create a redirect for that address and send it to the blackhole address
[email protected]
If the spam is being sent to multiple addresses that aren't in use then you can turn off the catch all address via the portal tool.
If you don't have the spam protection switched on then you can again do this via the portal (on most accounts) and it will scan the mails for spam and mark the subject. Of the spams I'm receiving from this the spam protection is catching almost all of them. You can then use messages rules within you mail client to move emails with [-SPAM-] in the subject to the bin.
If you only use the
postmaster@... address for communications from us then you could set up a rule in the mail client to only receive mail from our email addresses and bin everything else.
You can use software like Mailwasher to filter the mails. Some mail clients also will do spam scanning.
