Download SpamPal 1.70 beta

SpamPal is a small Windows program that is able to check your email for spam mail. The program can check mails received via the POP3, IMAP4 and SMTP protocols. The messages that are marked as spam can then be moved to another folder via a rule or put in the trash can. The first beta version was released on the forum yesterday introduced of the 1.70 branch. The main improvement in this release is the so-called transparent proxy: instead of changing settings in your e-mail program, you can now indicate in SpamPal which e-mail addresses should be checked for spam. In addition to the new transparent proxy, a number of other things have also changed. You can read exactly what those are in this topic or in the changelog posted below:

1.70 (Beta Release)

• New Transparent Proxy feature – click here to learn more
• Mail filtering:
  • New option to not call certain plugins if message already marked as spam/whitelisted; should improve performance if you only call slow plugins when necessary.
  • For POP3 and IMAP4 sessions, SpamPal will now pre-fetch messages to improve performance. (It already did this for POP3 sessions under certain circumstances, but now everyone can benefit!) This can be disabled from the port properties dialog.
  • Wasn’t starting POP3 prefetching whilst body-filtering was in progress; fixed.
  • Prefetching of POP3 headers wasn’t working for the last message in your inbox; fixed.
  • Fixed rare buffer overflow in POP3 code.
• User interface:
  • More tweaks to the way status window handles saving column sizes.
  • You can now enter hostnames as well as IP address and Netblocks in the blacklist & ignorelists of netblocks, the access control list, and anywhere you could previously enter a list of IP addresses/netblocks.
  • When selecting “run spampal” from installer, no longer gives error message if SpamPal service already running.
  • Added information messages to “add to blacklist” and “add to whitelist” dialogs. (Advice on the best way to lay out these windows would be appreciated, as I think they look rather ugly right now!)
  • New option in the Interface pane allows you to deactivate SpamPal’s checking that status window is always on main desktop – implemented because I found I couldn’t make it open the status window on my new second monitor.
  • Tweaked layout or Plugin pane or options dialog (thanks Steve!)
  • Added ‘donations’ page to options window
• Blacklist query:
  • Was recording some DNSBL result codes as negative values ​​in logfile – fixed.
  • Hostname lookups are now cached for a few hours; should give a minor improvement to UrlBody’s speed when you receive lots of spam advertising the same thing.
  • Fiddled around with DNSBL query multi-threading to hopefully make it yet more efficient.
  • New option on the “Advanced” pane to make SpamPal wait for all DNSBL queries to complete before starting to filter the message body.
• Windows Service Support
  • GUI client may now start slightly faster.
  • GUI client wasn’t always exiting properly if it failed to log into the service; fixed.
  • Changed way temporary folders are named by GUI client.
• Misc:
  • Converting config files from one language to another had become broken; fixed.
  • Update-checking doesn’t inform you of new beta-releases just because it thinks you’re using a beta.
  • Should now start up very slightly faster.
  • Fixed thread handle leak that’d crept into recent betas.
  • Logfile now reports when SpamPal attempts APOP authentication
  • New “Protocol logging” screen of the options window; allows you to create protocol-level logs of your mail sessions, which will be useful for debugging purposes. (Previous debugging versions already did this, but I’ve removed that code from the latest one.)
  • For debug-logging releases, two new registry keys allow you to turn debug-logging logging on/off and set debug-logging folder.
  • Now doesn’t try to call the unsupported function TryEnterCriticalSection if SpamPal crashes on a Windows 95/98/ME machine.
• source code:
  • Recent versions of lcc-win32 seem to have changed the values ​​they returned from vsnprintf – this could result in truncation of some configuration files when SpamPal was running as a service. Updated Spampal code to avoid this.
