ftpmail(1) General Commands Manual ftpmail(1)
NAME
ftpmail - FIFO-based Perl script for sending email based on proftpd TransferLog
SYNOPSIS
ftpmail [ --help ] [ --fifo fifo-path ] [ --from email-address ] [ --log xferlog-file ] [ --recipient email-address ] [ --subject email-
subject ] [ --smtp-server server-address ] [ --attach-file ] [ --auth smtp-auth-info-file ] [ --ignore-users regex-pattern ] [ --watch-
users regex-pattern ]
DESCRIPTION
ftpmail is a Perl script designed to read ProFTPD's TransferLog log entries, watching for uploads, and to send an automatic email notifica-
tion when uploads occur. To use ftpmail , you configure your proftpd daemon to write its TransferLog to a FIFO; the ftpmail program is a
FIFO reading program which then processes those log messages.
OPTIONS
--help Display a short usage description, including all available options.
--attach-file
If used, this will cause a copy of the uploaded file to be included, as an attachment, in the generated email.
--auth smtp-auth-info-file
Configures the path to a file containing SMTP authentication information. The configured file should look like this:
user username
password password
--fifo fifo-path
Indicates the path to the FIFO to which proftpd is writing its TransferLog. That is, this is the path that you used for the
TransferLog directive in your proftpd.conf. This parameter is REQUIRED.
--from email-address
Specifies the email address to use in the From email header. This parameter is REQUIRED.
--ignore-users regex-pattern
Specifies a Perl regular expression. If the uploading user name matches this regular expression, then an email notification is
NOT sent; otherwise, an email is sent.
--log xferlog-path
Since this script reads the TransferLog using FIFOs, the actual TransferLog file is not written by default. Use this option to
write the normal TransferLog file, in addition to watching for uploads.
--recipient email-address
Specifies an email address to which to send an email notification of the upload. This option can be used multiple times to
specify multiple recipients. AT LEAST ONE recipient is REQUIRED.
--smtp-server server-address
Specifies the SMTP server to which to send the email. This parameter is REQUIRED.
--subject subject
Specify a custom Subject email header for the email sent. The default Subject is:
User '$user' uploaded file '$file' via FTP
--watch-users regex-pattern
Specifies a Perl regular expression. If the uploading user name matches this regular expression, then an email notification is
sent; otherwise, no email is sent.
