Hello,
Ive installed FuzzyOCR plugin to work with SA. Ive installed all
dependencies. But I get error like this:
(Pipe Command "/usr/bin/jpegtopnm", Pipe exit code
1 (""), Temporary file: "/var/amavis/tmp/.spamassassin9636KEJrT7tmp")
[2006-12-16 18:24:03] Unexpected error in pipe to external programs.
Please check that all helper programs are
installed and in the correct path.
(Pipe Command "/usr/bin/giftopnm -", Pipe exit
code 1 (""), Temporary file:
"/var/amavis/tmp/.spamassassin9635oXpjtztmp")
[2006-12-16 18:25:10] Unexpected error in pipe to external programs.
Please check that all helper programs are
installed and in the correct path.
Moreover I would like to verify that SA+FuzzyOCR blok some email with
images atthacched..
How can I do?
Thanx,
rocsca
