.Os clamsmtp 
.Sh NAME
.Nm clamsmtpd.conf
.Nd the configuration file for 
.Xr clamsmtpd 8
.Sh DESCRIPTION
.Xr clamsmtpd 8
reads a configuration file when starting up. The location of the file is dependent
on how you compiled clamsmtp but it should usually be in either the
.Pa /usr/local/etc/
or 
.Pa /etc/
directories. If 
.Xr clamsmtpd 8
does not find it's configuration file it'll print a warning when it starts up along
with the location it's expecting to find it in. You can also specify a different 
location for a config file by passing the 
.Fl f
argument to 
.Xr clamsmtpd 8
.Pp
The settings are specified one per line. The setting names comes first, followed
by a colon and then the value. Comments start with the '#' character on a line 
of their own. Whitespace is ignored at the beginning of line, end of line and 
around the colons. 
.Pp
A sample configuration file can be found in the 
.Pa doc/
directory of the clamsmtp distribution.
.Sh SETTINGS
The various settings are as follows:
.Bl -tag -width Fl
.It Ar Bounce
When this flag is set 
.Xr clamsmtpd 8
actively rejects messages with viruses. This may cause the sender to receive
a message back notifying them of the virus. In most cases this is not a good
idea since many viruses spoof sender addresses. 
[ Default: off ]
.It Ar ClamAddress
Specifies the address to connect to 
.Xr clamd 8
on. See syntax of addresses below. 
[ Default:  
.Pa /var/run/clamav/clamd

.It Ar Listen
The address and port to listen for SMTP connections on. See syntax of 
addresses below. 
[ Default: port 10025 on all local IP addresses ] 
.It Ar Quarantine
Quarantine files that contain viruses by leaving them in the
.Ar TempDirectory
directory. The file names look like this (where X is a random 
character or number):
.Pa virus.XXXXXX
[ Default: off ] 
.It Ar MaxConnections
Specifies the maximum number of connections to accept at once. 
[ Default: 64 ]
.It Ar PidFile
This option causes 
.Xr clamsmtpd 8
to write a file with the daemon's process id, which can be used to stop the 
daemon.
[ Optional ]
.It Ar ScanHeader
A header to add to scanned messages. Put an empty value to supress adding
a header. 
[ Default: 'X-AV-Checked: ClamAV using ClamSMTP' ]
.It Ar OutAddress
The address of the SMTP server to send email to once it's been scanned. See 
syntax of addreses below. 
[ Required ]
.It TempDirectory
The directory to write temp files too. This directory needs to be 
accessible to both 
.Xr clamd 8
and 
.Xr clamsmtpd 8
[ Default:
.Pa /tmp
]
.It Ar TimeOut
The number of seconds to wait while reading data from network connections.
[ Default: 180 seconds ]
