Re: [magicmail-users] segfaults

[Michael Peddemors <michael@linuxmagic.com>]

Strange.. We did have a bug in previous versions to 0.7.1 that caused a 
segfault, if control files missing, but that was corrected.  However, this 
MAY be a new bug with a dependency on 'ip2country' that might have snuck in 
from our commercial version.  Please check to see if 'ip2country' and 
'gethostmxs' from the script directory are correctly installed and used.

Reviewing the INSTALL docs, I do not see anything about installing the 2 
scripts, so I suggest that you copy the two scripts to /usr/local/bin and let 
me know if that solves it for you.

PS You MUST have a control file to indicate the MSD_COUNTRY_CODE_PROG
(This was missing from the INSTALL descriptions)
This should be in /etc/magic-mail/control directory as 

"country_code_prog"

ie 
`echo "/usr/local/bin/ip2country" > /etc/magic-mail/control/country_code_prog`

I see that we need to fix up config_defaults.h to indicate the correct program
You can do this yourself to test, but if you have the control file, it will 
ignore this problem.  Actually, while we are at it, we should fix gethostmxs 
as well, Same problem. Control File is called 
'/etc/magic-mail/control/get_mx_rec_prog'

Fix via ...
echo "/usr/local/bin/gethostmxs" > /etc/magic-mail/control/get_mx_rec_prog

Or apply patch below, and do a make clean, make all

Thanks for pointing this out, and we will patch the sources and get another
