It looks like this:   TVqQAAMAA TVpQAAIAA TVpAALQAc TVpyAXkAX TVrmAU4AA TVrhARwAk TVoFAQUAA TVoAAAQAA TVoIARMAA TVouARsAA TVrQAT8AA TVrvAEQAe # MyDoom (*.zip) UEsDBAoAA # *.zip # UEsDBAkAA # *.z (gnu-zip) # H4sIADWWb # double Base 64 Windows Executable VFZxUUFBT # triple Base 64 Windows Executable VkZaeFVVR # Pif File TVoAAAEAA   And I try to unzip the file that have problem, the zip file contains (a.pdf, b.pdf, c.dpf and ‘._a.pdf, ._b.pdf, ._c.pdf’) >>> I try to just zip all the normal pdf files (except other files with  the ‘._’ in front, it is just 80-100 bytes, sure it is not a valid pdf file and you have error if you try to open it) and the toaster received and deliver to inbox just fine.   For another zip file with multiple gif files >>> the folder contains multiple gif files and a file ‘Thumbs.db’ --- windows generate this file for thumbnail preview. Somehow people zip the image folder and it includes this Thumb.db file and toaster will drop this mail if the db is included inside the zip file. Zip all gif files except this ‘Thumb.db’ >>> it is OK.   This 2 zip files have no problem sent to yahoo, hotmail and others mail server. Any suggestion?   Thanks, Philip     From: Jake Vickers [mailto:[EMAIL PROTECTED]] Sent: Friday, August 04, 2006 8:44 PM To: qmailtoaster-list@qmailtoaster.com Subject: Re: [qmailtoaster] zip file attachment won't deliver to mailbox.   Philip Moy wrote: Hi,   Did anyone experience sent a zip attachment and it won’t go to users Mailbox?   Here is the error message that I got from different mail server:        There was a SMTP communication problem with the recipient's email server.  Please contact your system administrator.             <qcomtornts1.qualicom.com #5.5.0 smtp;554 invalid message content  (#5.3.2)>   And:   This mail message contains standard MIME attachments.  If you see this note, your e-mail program does not support MIME.  You may need a MIME- compliant mail reader to read any non-text attachments in this message.   CC to yahoo or hotmail without any problem.   I have 2 zip files with the same problem:   1 zip file with 10 pdf files inside, I sent the 10 files in single mail without any error. If I zip it up and sent >>> it won’t deliver to mailbox. Same as another one, 1 zip file with 20 gif files inside >>> sent all 20 files is OK but not zip it up and sent.   Any idea on where to look the errors and solve it? Thank You Comment out the line for ZIP files and MyDoom (zip) in your /var/qmail/control/badmimetypes and then run qmailctl cdb (new Toaster) or /var/qmail/bin/qmail-badmimetypes (old version). That should solve your problem. As I said before, comment out the signature for the MyDoom Zip file (UEsDBAoAA) and rebuild the cdb. This should solve your zip file problem. The MyDoom signature also hits on good ZIP files sometimes, especially with directories with spaces in the ZIP file. If you have already sent the file to a Yahoo or hotmail account, look at the encoding of the MIME for the first 9 chars and see if they match anything in badmimetypes. If not, then look at badloadertypes and search the ENTIRE message for those signatures (mime tpyes only matches the first 9 chars, and bad loader matches ANY PART of the MIME.).
