Hi, I use Horde 3, IMP 4 and Courier-IMAP. It's ok if I received message with small attach file(<=1MB). But when I received a message with large attach file, it's can't download this attach file (>1MB). I try to receive mail by POP3, it's OK. It's import to me, please help me to solve my problem. Thanks in advance! Fan Teo
