I posted the message below on the Mac OS X user list, but only got one response, which I found an unsuitable workaround. So perhaps those on the Ti list can bring a different set of resources to my question, and apologies for cross-postings. Original question: Hi all! I am persisting with Mail, but beginning to drift back into Eudora usage. I have attempted on a number of occasions to send MS Word and Excel files to various recipients from Mail, only to have them say they are unable to open the documents, or if they can they're mangled (in the case of Excel.) The Excel files were originally sent to me from Windows boxes, and after filling in (taxes!) being mailed back to the same. I can open them on my own Windows box after transferring them via the network, not email, so the corruption takes place at the Mail side of things. To confirm, I emailed the same files from both Mail and Eudora to Outlook Express 5 in Virtual PC W98. Eudora's opened as doc files, while Mail's came through as generic .dat files, with W98 asking how it should open them. Wordpad opened the Eudora-sent files. Any ideas what Mail is doing, and where to go to change it, whatever it is? I can get by using Mail to receive and take advantage of its Spam technology, and send attachments from Eudora, but it's really a PITA to do it that way. All help gleefully accepted.
