Dear list,
using Exim 4.5.1 with a MySQL-backend, I ran into a problem when the
recipients-header contained a single quote.
Single quote garbles my SQL-syntax for the recipients mailaddress-lookup in
the database.
Exim replies to the sender: "Temporary local problem - please try later",
while the logfile shows:
2005-11-04 11:25:31 H=(***.***.**) [**.***.***.***] F=<foo'foo@???>
temporarily rejected RCPT <account@???>: MYSQL: query failed: You
have an error in your SQL syntax. Check the manual that corresponds to your
MySQL server version for the right syntax to use near ' foo@???' rlike
sender' at line 1
So I tried to catch all special MySQL-characters in a system-filter, first
of all the single quote. Without success.
if $header_to:,$header_cc:,$header_bcc: matches "\\'"
then
fail text "Delivery failed- Illegal characters in mailaddress."
endif
if $header_to:,$header_cc:,$header_bcc: contains \047
then
fail text "Delivery failed- Illegal characters in mailaddress."
endif
and a lot of other variants.
Anybody out there could help me out with a filter or give me a clip of an
ACL that checks for the address-headers?
