Hello Martin

>>In my case, losing some emails could risk missing some business oportunitites

But what of the risk that an important e-mail is missed while you try not to waste too much precious time sorting the grains of wheat from the voluminous chaff?!

I'm not trying to tell you your business... but consider the opportunity cost of wading through all this junk every day. And what if you go on holiday for a week?!

Perhaps you could put an auto-reply on your old address saying that the company has upsized its e-mail to serve customers better and this address no longer works, with a phone number so people can call you or a web page where they can go for updated details?

Regards
