Sure. giftopnm will do it. The FuzzyOCR plugin is using some
other tool that will also do it, I don't recall what just at the
moment.
giftopnm wont do it as far as I tested it... it only extracts the
first frame...

RE: Animated images in mails
FuzzyOCR (http://wiki.apache.org/spamassassin/FuzzyOcrPlugin) will do
what you want.
There's a small error in 2.3b's FuzzyOCR.pm which means it doesn't
recognize jpeg images. To fix that, change
elsif ( substr($picture_data,0,5) eq \x89\x50\x4e\x47 ) {
to read
elsif ( substr($picture_data,0,4) eq \x89\x50\x4e\x47 ) {
(search for 0,5 in your text editor)
Cheers,
Phil

Today I got animated spam. The first frame only with dots an lines, the
second frame with spam text, the third frame again with dots and lines.
The
duration of the text frame is very long, the others are very short.
Is there a command line utility which can extract animated GIFs?

Various... imagemagick can either extract them or put them into one image, gifasm can split them into multiple files, etc. FuzzyOcr utilizies both as needed to scan animated gifs.
