501 Badly structured mime attachment

[John Logiudice]

Hello, I've recently set up a server on Linux using qmail 1.03.  Several = different users here received bounces like this one when sending mail: >  Hi. This is the qmail-send program at opalgroup.net. >  I'm afraid I wasn't able to deliver your message to the following = addresses. >  This is a permanent error; I've given up. Sorry it didn't work out. > >  <[EMAIL PROTECTED]>: >  209.116.174.162 failed after I sent the message. >  Remote host said: 501 Badly structured mime attachment. Most attachments are going through fine, and the same users were able to = send attachments to other recipients.  The attachments that had this = trouble ranged in size from a 128kb .DOC file, to a 4mb .EPS file. =20 Although not a major problem -- yet -- I'd like to know if there is some = configuration issue on my end that will prevent this.  All the users who = had this trouble are using Outlook Express 5. Please let me know if there is any more info I should supply. Thanks, John
