SYNOPSIS

rspamc [options] [command] [input-file]...

rspamc –help

DESCRIPTION

rspamc is a simple rspamd client, primarily for classifying or learning messages. rspamc supports the following commands:

Control commands that modify rspamd state are considered privileged and require a password to be specified with the -P option (see OPTIONS, below, for details).

This depends on a controller's settings and is discussed in the rspamd-workers page (see SEE ALSO, below, for details).

Input files may be either regular file(s) or a directory to scan. If no files are specified rspamc reads from the standard input. Controller commands usually do not accept any input, however learn* and fuzzy* commands requires input.

OPTIONS

-h host[:port], --connect=host[:port]

Specify host and port

-P password, --password=password

Specify control password

-c name, --classifier=name

Classifier to learn spam or ham (bayes is used by default)

-w weight, --weight=weight

Weight for fuzzy operations

-f number, --flag=number

Flag for fuzzy operations

-p, --pass

Pass all filters

-v, --verbose

More verbose output

-i ip address, --ip=ip address

Emulate that message was received from specified ip address

-u username, --user=username

Emulate that message was received from specified authenticated user

-d user@domain, --deliver=user@domain

Emulate that message was delivered to specified user (for LDA/statistics)

-F user@domain, --from=user@domain

Emulate that message has specified SMTP FROM address

-r user@domain, --rcpt=user@domain

Emulate that message has specified SMTP RCPT address

--helo=helo_string

Imitate SMTP HELO passing from MTA

--hostname=hostname

Imitate hostname passing from MTA (rspamd assumes that it is verified by MTA)

-t seconds, --timeout=seconds

Timeout for waiting for a reply (can be floating point number, e.g. 0.1)

-b host:port, --bind=host:port

Bind to specified ip address

-j, --json

Output formatted JSON

--ucl

Output UCL

--raw

Output raw data received from rspamd (compacted JSON)

--headers

Output HTTP headers from a reply

--extended-urls

Output URLs in an extended format, showing full URL, host and the part of host that was used by surbl module (if enabled).

-n parallel_count, --max-requests=parallel_count

Maximum number of requests to rspamd executed in parallel (8 by default)

-e command, --execute=command

Execute the specified command with either mime output (if mime option is also specified) or formatted rspamd output

--mime

Output the full mime message instead of scanning results only

--header=header

Add custom HTTP header for a request. You may specify header in format name=value or just name for an empty header. This option can be repeated multiple times.

--sort=type

Sort output according to a specific field. For counters command the allowed values for this key are name, weight, frequency and hits. Appending :desc to any of these types inverts sorting order.

--commands

List available commands

RETURN VALUE

On exit rspamc returns 0 if operation was successful and an error code otherwise.

EXAMPLES

Check stdin:

rspamc < some_file

Check files:

rspamc symbols file1 file2 file3

Learn files:

rspamc -P pass learn_spam file1 file2 file3

Add fuzzy hash to set 2:

rspamc -P pass -f 2 -w 10 fuzzy_add file1 file2

Delete fuzzy hash from other server:

rspamc -P pass -h hostname:11334 -f 2 fuzzy_del file1 file2

Get statistics:

rspamc stat

Get uptime:

rspamc uptime

Add custom rule's weight:

rspamc add_symbol test 1.5

Add custom action's weight:

rspamc add_action reject 7.1
