[Mimedefang] timeout before data read, where=body

[Marcus]

Hi,

since yesterday I get a "timeout before data read, where=body" with a
single mail sent via googlemail. It's not spam/not a virus and from the
subject line and the message size of 25049183 it seems to have an
attachment (may be a PDF). Clamav scans up to a size of 10MB. The
message size itself seems not to be the problem. I've seen bigger mails
in the log.

mimedefang                        2.64-6 
sendmail                          8.14.3-5+lenny1
spamassassin                      3.2.5-2+lenny2
clamav-daemon                     0.95.3+dfsg-1~volatile1
