How can I use fetchmail with InterChange?
You can’t. At least not if you want to be able to see attachments. InterChange has a bug similar to the MailMax server; it reports the message length with attachments but doesn’t download them on TOP or RETR. On Jan 9 2001, the people at InfiniteMail sent me mail informing me that their new 3.61.08 release of InterChange fixes this problem. I don’t have any reports one way or the other yet.
