Weirdness -- Delayed email

[Bob Schroeck]

I meant to post this a couple days ago, but forgot to...  Something weird happened with my email earlier this week -- over the course of several hours I received about a dozen emails that were months old -- one almost a year old -- interleaved among my normal traffic.  I know these weren't copies of stuff I had received, because there was at least one personal message that I know I hadn't received before and would have responded to had it showed up in October when it had been sent.  Several others were listings from job boards, ranging from April of last year to January of this year.  There was no rhyme or reason, no pattern, to the selection. 
So... has anyone else had anything like this happen to them?  Anyone have a clue what might have happened?
