Plugin Downloads

Product Description Download
(SpamAssassin Plugin)
SNF4SA is an antispam plugin for SpamAssassin that connects SpamAssassin to SNFServer via our XCI protocol (TCP-Localhost). SNF4SA is included in the SNF Client/Server for *NIX package above. This SNF4SA package is for those who may want to install SNF4SA on a Windows implementation of SA or otherwise separately from the *NIX client server version of SNF. (Both the linux and windows version is included but the difference is only where temp files go.) SNFServer or the SNFMulti engine in some form is required for SNF4SA to work and must be installed separately - does not contain an SNFMulti implementation. Learn More.   SNF4SA  
(Sendmail/Postfix Milter)
Unix (g++ source) based milter connects postfix or sendmail MTAs directly to the SNFMulti engine. SNFMilter also provides an XCI interface when operating for use with SNFClient for GBUdb manipulation, status reporting or other functions. Learn More.   SNFMilter
