[otrs] corrupt attachment in email

Dear All, We are using OTRS 2.1.4, postresql, and postmaster.pl script fot incoming email/tickets. Can somebody tell me, why does otrs corrupt attachment in incoming emails? I tried a lof of times, and I am sure postmaster.pl script is the murder! I send email with attachment to OTRS, and when I open file in the ticket, it is invalid! -- Valkai Jozsef +36 70 36 28 147 valkaij@externet.hu jvalkai@gmail.com lat:N 47° lon:E 19°
