Appendix A 75
The [smtpgw.access] section includes the following options used to control the
access of SMTP clients:
DenyUnresolvedConnect=true|false – Defines the rules for connecting to
SMTP clients whose hosts are not listed in DNS records. The default
value is false. To reject such connections, set the option to true.
DenyUnresolvedMailfrom=true|false – Defines the rules for receiving
messages from recipients whose hosts are not explicitly listed in DNS
records in the MAIL FROM field (SMTP command). The default value is
false. To reject receiving messages from such SMTP clients, set the
option to true.
Rule – this option is presented in the form of a table (list of parameters) that
defines rules for relaying messages via the application. Each rule is de-
fined by a line of the following format:
Rule=rule from address_or_mask to recipient_domain
where:
rule
– determines whether the client shall be granted access (values
are: allow or deny);
address_or_mask
– determines the senders’ IP-address or mask
(value’s format x.x.x.x or x.x.x.x/x.x.x.x or x.x.x.x/y);
recipient_domain
– determines the recipient’s domain (special symbols
"*" and "?" can be used). Value “any” stands for the name of any do-
main.
When selecting rules from the list the first rule matching the pair ad-
dress_or_mask / recipient_domain will apply.
The [smtpgw.ave] section contains options for scanning messages for viruses:
Cure=true|false – Disinfect infected objects. The default value is false. To
enable this mode, set the option to true.
ScanArchives= true|false – Scan archives. The default value is true. To
disable this mode, set the option to false.
ScanMailBases= true|false – Scan mail databases. The default value is
true. To disable this mode, set the option to false.
ScanTimeout=0 … 3600 – Time (in seconds) during which an anti-virus
scan module can process a single object. If the scan time exceeds the
limit, the object is assigned the Error status (scan error).
UseIChecker=true – Use iChecker technology to scan for viruses. The de-
fault value is true. To disable the mode, set the parameter to false.
