OK, I've found that it was a client software error where CRAM-MD5 login is
advertised first. Pegasus mail wouldn't keep trying to get to plain
LOGIN, but The BAT! would "fail back" from CRAM-MD5 to plain LOGIN and
roaming SMTP relay works fine.
If you're using an older SMTP AUTH patch, CRAM-MD5 won't work properly. Use the patch that's in the contrib directory of vpopmail 5.4.x instead (and note that you may need to update your qmail-smtpd/run file as well).
You really should have CRAM-MD5, since it's the only SMTP AUTH protocol that encrypts the password when sending. Note that you'll also need to enable cleartext passwords in vpopmail for it to work properly.
If you can't use CRAM-MD5 for some reason, edit the source to qmail-smtpd and remove it from the text sent to the SMTP client (just search for CRAM-MD5 and it should be easy to find).
