I belive it's SquirrelMail issue - it's just unable to render
(highlite urls in text and so on) the message in question in a
reasonable time. I'm not sure how SquirrelMail's rendering works,
but if it's regexp-based it may take forever for such a big
You may try to wait a bit more - but if I'm right 240 seconds of
execution time won't be enough, it may take days to complete. And
make sure you tuned nginx's fastcgi_read_timeout (it's 60s by
default). You browser timeouts may be a problem too.
Anyway, it doesn't looks like nginx issue.
