Hi, I have this issue. recently The server receives emails with attachments, i click the attachment through squirrelmail and it open's any pdf, jpg etc in the web browser. When it is either forwarded or collected via email client (outlook) it's attachments which are received empty ie. 0 kb. I logged in via squirrelmail and forwarded an email to my gmail account, i received it but still had 0 kb attachments. and when i tick box and forward in squirrel mail, at the preview attachments state 0 kb. server is Debian GNU/Linux 8.2 (jessie) ISPConfig 3.0.5.4p8
