Hi All,
I'm having the following issue:

An user does not receive mail from certain other users and when the mail comes with some types of attachments. Ex: The user can receive mail from user "B" with an excel attachment, but does not receive the mail from user "B" when it is sent with a word attachment.

When we check zimbra.log it appears as all the mail to the user, sent from user "B" is sent. We checked the status, it appear as queued and later in the log, the status appears as sent.

I really don't understand how this happens, any clue??

Regards,
E.
