I recently redid my hard drive with XP, SP2 etc. Since then some email
recipients can open attachments from me - small word files - and some can't.
I've checked the OE settings, and have set them the same as on my other pc,
which works fine. The same problem occurs if I send using Outlook, but not
if I send using Pegasus. Also, I can send OK from my btinternet webmail on
that pc. Some of my recipients are pretty savvy and they've told me the
files are a bit smaller than they should be when they arrive.For one
recipient, they arrive as "mim" files - so he says - but for the otehrs they
look lie Word docs. My recipients can open the attachments using their own
webmails, but not using Outlook or OE in XP.

I've no idea what this is - can anyone help?

Thanks.
