Configuration

The configuration files for Dr.Web and email filter can be found in the /hsphere/local/config/drweb/ directory:
drweb32.ini - main config-file for DrWeb
drweb_qmail.conf - main config-file for email filter.

Dr.Web checks and optionally strips email attachments with extensions specified in /hsphere/local/config/drweb/drweb32.ini, for example:
FilesTypes = EXE,COM,SYS,OV?,BAT,BIN,DRV,PRG,BOO,SCR,CMD,VXD,386,DLL,FON,DO?
FilesTypes = XL?,WIZ,RTF,CL*,HT*,VB*,JS*,INF,AR?,ZIP,R??,PP?,OBJ,LIB,HLP,MD?
FilesTypes = INI,MBR,IMG,CSC,CPL,MBP,SHS,SHB,PIF

To strip the attachments, set ArchiveRestriction = reject. To keep the attachments, set ArchiveRestriction = pass.

Updates

By default, we add daily Dr.Web auto-updates to root crontab on the mail server, for example:
02 4 * * * /hsphere/local/drweb/update/update.pl
It means that auto-update starts every day at 4:02 AM.
