MichaelM - is my memory fading? Haven't we met?

If it is Heather, Say hello to the (Commoners for me)
I get her e-mails OK.

Spam blockers usually look for tell-tale signs like HTML e-mails (colour and fancy fonts), graphics, words like "free", probably $$$ signs and any "To" addresses that are not the person receiving the mail. Lists in the "To" box also raise the spam count.

If it is not Heather's e-mails then her hubby would be pretty switched-on to these things - he might have insights for you - Amphisbena(?) Music.

If there is a Viagra Blues in the repertoire you ain't gonna advertise it via e-mails too well.
