Kaspersky Lab kaspersky mail gateway 5.5 Mode D'Emploi

6.12. Additional informational 

header fields in messages 

Application allows addition of some supplementary information to mail 
messages. Let us examine closer two methods of adding new informational 
header fields to a message: 

• 

Add extension header field to mail message. 

The information may describe application version, date when the anti-
virus databases were last updated, time and result of message scanning 
(determined by the AddXHeader parameter in the [smtpgw.policy] 
section of the application configuration file). 
Header format: 

X-Anti-Virus: <product name and version>, bases: <date 
of the last update to anti-virus databases in YYYYMMDD 
format> #<the number of records in AV databases>, 
check: <scan date in YYYYMMDD format> <scanning status 
or not_checked> 

E.g.: 

X-Anti-Virus:Kaspersky Mail Gateway for Linux GLIBC 
2.2 version 5.5.58/RELEASE, bases: 20041101 #102746, 
check: 20041210 clean 

• 

Add disclaimer text to mail message body.  

The information will be added as plain text; it may contain any statement 
generated in accordance with the security policy (or other rules) of a 
specific organization (the AddDisclaimer parameter in the 
[smtpgw.policy]  section). The default message text notifies that the 
message has been scanned by Kaspersky Mail Gateway. Upon 
administrator’s demand the application can modify the information format 
(e.g., generate disclaimer message as a HTML text).
