Spam not a lot...

[#1]

Since the move to Greenby spam starting has started to appear at first it was 5-6 a day and they were all to a particular email address I set up years ago when purchasing Adobe software.

On my email account at Greenby I set up a block of all emails sent to the Adobe address and the amount of spam has reduced to 1 or 2 a day, I don't understand how some are getting through if that have the address I have blocked. On Thunderbird I've now set up a filter that sends the offending emails to delete which I then clear.

Is there a way to stop the emails even arriving...I notice on the Thunderbird filter there is the option to "Delete from POP Server" would that do the trick?

Meanwhile the other day I received this phoney email....

Spam comes from a spammer running a script that consumes an email list including our email address.
Greenby is not implicated in the level of spam sent to our mailboxes.  

In fact the opposite may be the case,  the Plusnet [-SPAM-] filter stopped working almost a year ago
and Greenby have quite an aggressive Spam Filter that is in the Email Settings of www.greenby.com

Think very carefully before enabling the Greenby Spam Filter if you use POP3. The spam filter will divert messages to the server's Spam folder and these will not be seen in the POP3 collection which only reads from the mail server's Inbox.

This is important as many one time passwords / number codes are snagged as spam and that would block the ability to receive the two factor component of an account login or of its password recovery process.

The POP3 delete from server is about how many weeks or months of messages to keep on the server before deletion, this is unrelated to spam.

Thank you for the information. What I don't understand is how the emails slip through the Greenby filter I set up, the filter in Thunderbird catches the offending emails.
