Pine and Qpopper questions.

Hey everyone, I am a bit of a lurker on the list but I have a couple of questions regarding Pine and Qpopper. First with Pine I am having a very strange problem and I am wondering if others have seen this. I have sendmail configured to work with virtual hosts (two domains) and I am masquerading. When I use /bin/mail or connect via a pop3 client and send a mail out masquerading woks fine. But when I use pine the mail sent is not masqueraded and the full hostname is used. Any ideas? Is it a problem with pine? The second question I have concerns qpopper and how it is configured by default. Is it using APOP or just plain text by default. Or is it using both? Thanks Benjamin
