Even at a gross scale because the people (and malware) sending malicious (and spam) email are small in number and use a small set of techniques even back in the days of SPAM-L different big email providers would see large differences in the amount of spam attempted. So one ISP might say "we are seeing a huge surge", and another ISP would say "quiet today". It use to be relatively easy to sort, as people introduced more filtering the spammer have got smarter. I'm averaging two spam a day since start of March, not counting annoying marketing emails from people contacted for my current work. I don't do any particular clever spam filtering on this email server. Blacklisting a bunch of Windows executable attachment types, use of well known spam blacklist and some (hardly any now) greylisting. I don't rigidly enforce SPF or DKIM, and my email is as out their as it can be. Quite a lot of this "spam" I see are MS Windows based malware, or people who have previously harvested address books (Yahoo), so purports to come from friends or relatives, but doesn't use their email address, and contains only a link, often a search engine link. So "malicious" email is probably better than "spam", in that it is nearly all criminal in origin rather than "over enthusiastic marketing". -- The Mailing List for the Devon & Cornwall LUG https://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
