Hi,
In function rf_get_munge_headers() is used string_sprintf() to concatenate
strings, but in case when size of expand_string(rblock->extra_headers)
> STRING_SPRINTF_BUFFER_SIZE we have a trouble.
In real life exim do nothing with messages that have very long "To:" :
>mailq
63d 23K 1BSQgf-000AvD-Ht <apache@???>
sand@???
>exim -v -M 1BSQgf-000AvD-Ht
LOG: MAIN PANIC DIE
string_sprintf expansion was longer than 8192
Exim config :
userforward:
driver = redirect
check_local_user
file = $home/.forward
no_verify
no_expn
check_ancestor
allow_filter
file_transport = address_file
pipe_transport = address_pipe
reply_transport = address_reply
headers_remove = from:to:cc
headers_add = "${if def:header_from: {From: ${perl{strip_trailing_space_characters}{$h_from:}}\n} }\
${if def:header_to: {To: ${perl{strip_trailing_space_characters}{$h_to:}}\n} }\
${if def:header_cc: {Cc: ${perl{strip_trailing_space_characters}{$h_cc:}}\n} }"
>cat ~sand/.forward
# Exim filter <<== do not edit or remove this line!
if $header_to: contains "sand@???"
then
save $home/Mail/archive
endif
if $header_cc: contains "sand@???"
then
save $home/Mail/archive
endif
So exim have troubles with modifying header by header_add routine.
