Sierra's Hallmark Card Studio Deluxe Data Location

Sierra's Hallmark Card Studio Deluxe 1.0 creates a registry entry to indicate where it stores event planner calendar entries and address book entries. The registry key HKEY_LOCAL_MACHINE\SOFTWARE\Sierra OnLine\Hallmark Card Studio\Deluxe\1\Paths might have the following information for a default installation.

Value name:DataPath
Value data:c:\SIERRA\CardStudio\Data

On a Windows XP system, you would find the PLANR32.DAT file it uses at that location. However, on a Windows 7 system, the data might actually be stored in PLANR32.DAT in another location specific to the user account from which the data is accessed, .e.g for a user with an account name of Liza, the data directory would be C:\Users\Liza\AppData\Local\VirtualStore\SIERRA\CardStudio\Data, assuming you selected the default location for installing the software rather than putting it under C:\Program Files\SIERRA\CardStudio as I would do. The PLANR32.BAK backup file it creates when you update the data would be in the same location.

Note: the VirtualStore registry entry is an example of Registry virtualization. According to Microsoft, "Registry virtualization is an application compatibility technology that enables registry write operations that have global impact to be redirected to per-user locations. This redirection is transparent to applications reading from or writing to the registry. It is supported starting with Windows Vista."

But, you can have Card Studio look elsewhere by changing the regsitry value for DataPath. E.g. you could have the program on two systems look in a directory at a network location for the data, so that the two systems would share the same data. For instance you could put \\MyServer\Shared\Sierra\CardStudio\Data in that registry entry to have it look on a system named MyServer with a directory shared as Shared. Note: you will have to run regedit from an administrator's account to be able to update the registry entry.

HKEY_LOCAL_MACHINE\SOFTWARE\Sierra OnLine\Hallmark Card Studio\Deluxe\1\Paths

Value name:DataPath
Value data:\\MyServer\Shared\Sierra\CardStudio\Data

Using SpamCop Blocking List (SCBL) with Sendmail

I've been getting far too much spam in my inbox despite using 6 different DNSBL's currently with sendmail. The blocklists I'm using on my email server do block a lot of spam, but a lot still gets through. I just checked a report I generate at midnight each day on how many messages were blocked by each list I am currently using and saw the following for yesterday:
Mon 11/16/2009

0 	 McFadden Associates E-mail Blacklist
70 	 Spamhaus Block List
4687 	 Passive Spam Block List (PSBL)
2496 	 Spam and Open Relay Blocking System (SORBS)
50 	 Swinog DNSRBL
14 	 Not Just Another Bogus List (NJABL)

7317 	 Total

The McFadden blacklist hasn't been working for quite some time; I should have removed it from sendmail's /etc/mail/sendmail.mc file previously. I removed it today and added the SpamCop Blocking List (SCBL).

I decided to add that list after reading a comment at Blocking Spam That Are In A Foreign Language by Low Jeremy about its usefulness in blocking messages in a foreign language. I've been getting a lot of messages that appear to be in Russian. Since I can't read Russian, such messages are of no avail to the spammers and are exceedingly annoying to me, since they clutter my inbox every day.

I'm using sendmail on the server, so I replaced the reference to the defunct McFadden Associates E-mail Blacklist in /etc/mail/sendmail.mc with FEATURE(`enhdnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?"$&{client_addr}', `t')dnl.

There are instructions for incorporating an SCBL check into various email server programs at How do I configure my mailserver to reject mail based on the blocklist? Specific instructions for sendmail are at SpamCop FAQ: Sendmail.

I followed the suggestion of using enhdnsbl, an enhanced version of DNSBL, rather than dnsbl as I'm using in /etc/mail/sendmail.mc for other blacklists on the system, because I have a recent version of sendmail and because the SpamCop site had the following information:

.

Some problems have been found with later versions of Sendmail.

The easiest fix may be to use the second method above, enhdnsblk instead of dnsbl.

SpamCop uses 'rbldns' to serve it's blacklist information. Rbldns does not yet have support for IPv6, but newer versions of sendmail (8.12.0 and greater) try IPv6 before IPv4. Sendmail asks for an AAAA record instead of an A record and SpamCop rejectes the query - resulting in spam slipping through the filters.

There are instructions for disabling AAAA (IPv6) queries from sendmail at Disable AAAA (IPv6) lookups without recompiling Sendmail, and the sendmail.org site states the following, but I decided to just use the enhdnsbl approach.

Some DNS based rejection lists cause failures if asked for AAAA records. If your sendmail version is compiled with IPv6 support (NETINET6) and you experience this problem, add

define(`DNSBL_MAP', `dns -R A')

before the first use of this feature. Alternatively you can use enhdnsbl instead (see below).

I deleted the McFadden blacklist entry and added the SCBL entry to the end of the list of blacklists I check. I now have the following in /etc/mail/sendmail.mc:

FEATURE(local_procmail, `', `procmail -t -Y -a $h -d $u')dnl
FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl
FEATURE(`blacklist_recipients')dnl
FEATURE(`dnsbl', `sbl.spamhaus.org', `550 Spam Block: mail from $&{client_addr} refused - See http://www.spamhaus.org/sbl/')dnl
FEATURE(`dnsbl', `psbl.surriel.com', `550 Spam Block: mail from $&{client_addr} refused - see http://psbl.surriel.com/')dnl
FEATURE(`dnsbl',`dnsbl.sorbs.net',`550 Spam Block: mail from $&{client_addr} refused - see http://dnsbl.sorbs.net/')dnl
FEATURE(`dnsbl',`dnsrbl.swinog.ch',`550 Spam Block: mail from $&{client_addr} refused - see http://antispam.imp.ch/spamikaze/remove.php')dnl
FEATURE(`dnsbl',`dnsbl.njabl.org',`550 Spam Block: mail from $&{client_addr} refused - see http://njabl.org/lookup?$&{client_addr}')dnl
FEATURE(`enhdnsbl', `bl.spamcop.net', `"Spam blocked see: http://spamcop.net/bl.shtml?"$&{client_addr}', `t')dnl

I regenerated sendmail.cf with m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf and then restarted sendmail with /etc/init.d/sendmail restart.

A few minutes after I restarted sendmail, I checked /var/log/maillog to see whether the SCBL had blocked any spam and found it had already blocked 21 messages.

# grep spamcop /var/log/maillog | wc -l
21
