[qmailtoaster] zip file attachment won't deliver to mailbox.

[Philip Moy]

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   Philip
