In the overall / global / world wide spam outcome there was no significant rising of the overall spam level at that time:

http://securelist.com/tag/spam-statistics/
https://www.spamcop.net/spamgraph.shtml?spamyear

So this mean your rising level of (recieved!) spam should have (one or a mix of) the following reasons:

 - Your Email address got handled over / selled within a spammer email-address package or 

 - grabbed somewhere (i.e. from a Windows users PC ;) from additional spammers - as "older" and/or widely used a email address is, as more "known" it is usually to any spammers

 - Apples algorithms got better tricked by current spammers at that time - fighting spam is a steadily back and forward between spammers and mails ervice providers since Email exists - but even incompetent mail service providers lead to less good filters because they will catched als false positives which leads users to "why did my apple address did not recieve mails from that 'sender' while others could recieve it?". So Mail providers have to reopen their filters from time to time a bit to avoid blocking of "false positives" (which are - at least on a technical level - correct positives...). 

I.e. the hype around MS Exchange (SBS) and some "Exchange security" products leaded to many badly driven MXes and MTAs around because nearly every small Windows admin feel "capable" to run a business quality email service on the public internet while i.e. hardly abusing RFCs.

While it is possible to reduce down to 1%-3% of spam it is not possible to filter it completely without the risk of false positives. This affects even big players like Apple or Google too.


cheerioh,


Niels.
