I am running postfix-2.6 with cyrus-imapd-2.3 server. Recently one of my user complains that when he sends mails some time grabage character are automatically added in mail body. Strangley if he send mails to more than one person some people get mails in correct format, but some people got garbage mails.
Kindly help to resolve this issue. Thanks in advance.
My user are using outlook mail client for sending mail.
