Click the Check Now button, and SpamSieve will tell you whether a newer version is available for download. By default, SpamSieve will automatically check for new versions each time it is launched and once per day. You can disable this feature by unchecking the checkbox.
If a new version is available, SpamSieve will tell you what’s new in that version. Click Download to have SpamSieve download the .dmg file for the new version to your Internet downloads folder. (You can change the folder in Safari’s preferences.) Click Download & Install to have it download the .dmg and then update the installed SpamSieve application to the new version.
To check for a new version, SpamSieve contacts a Web server at c-command.com. SpamSieve transmits the following information to the server: the name of the product (SpamSieve) and its version, the version of Mac OS X, the kind of processor that the Mac has, whether SpamSieve has been purchased, the name of the current mail program, and the name of the current language. This information is used to guide future development. No personal information is transmitted.
Note: The Software Update… menu command is not present if you purchased via the Mac App Store. Updates are available via the App Store application.
