I am getting a lot of email dated a month of more in the future. How do I best filter these out as junk? I tried making a regular filter, but can't find a way to set it to "greater than today."

I have forwarded (from my Thunderbird account) an email from our local hospital about an appointment to my mailfence address three times now, but all three were deemed undeliverable by the mailer-Daemon. I removed all links on the third attempt in case that was the problem, but no luck.

Error code: 554 Rejected : Spam ?

For further assistance, please send mail to postmaster.

How do I do that? Is my question. Is there a 'Postmaster' address to use?

Many thanks David Edwards

I want to create a filter to match any of the 20 addresses on my list. Rather than manually repeating the 'add rule' 19 times, I hoped to import all 20 at once.

Creating a filter with 'to' and putting a comma separated list there doesn't seem to work; the addresses won't be matched. I can't find a config file to manually edit in my profile directory for filters, or an extension to create this filter.

My end-goal is to add this 'blacklist' of my old e-mail addresses that have been leaked to a spam filter. These messages already end up in my spam folder by a rule at my provider, but I want to mark them as spam too, so I can sort through the spam folder more easily to find false positives.

Thanks in advance!
