7
8       Scan for viruses using configured virus scanner or manage infected mes‐
9       sages using search criteria.

SYNOPSIS

12       cyr_virusscan [ -C config-file ] [ -s imap-search-string ] [ -r [ -n] ] [-v] [ mboxpattern1 ... ]
13

DESCRIPTION

15       cyr_virusscan can be used to invoke an  external  virus  scanner  (cur‐
16       rently  only  ClamAV is supported) to scan specified IMAP mailboxes. If
17       no mboxpattern is given, cyr_virusscan works on all mailboxes.
18
19       Alternately, with the -s option, the IMAP SEARCH string will be used as
20       a  specification of messages which are assumed to be infected, and will
21       be treated as such.  The virus  scanner  is  not  invoked.  Useful  for
22       removing messages without a distinct signature, such as Phish.
23
24       A table of infected messages will be output.
25
26       To remove infected messages, use the -r flag. Infected messages will be
27       expunged from the user's mailbox.
28
29       With the notify flag, -n, notifications will be appended to  the  inbox
30       of  the  mailbox  owner,  containing message digest information for the
31       affected mail.  This flag is only works in combination with -r.
32
33       cyr_virusscan can be configured to  run  periodically  by  cron(8)  via
34       crontab(5) or your preferred method (i.e. /etc/cron.hourly), or by mas‐
35       ter(8) via the EVENTS{} section in cyrus.conf(5).
36
37       cyr_virusscan reads its configuration options out of the  imapd.conf(5)
38       file unless specified otherwise by -C.
39
40       Note  that  Cyrus  does  not  ship with any virus scanners: you need to
41       install one separately to make use of it with Cyrus.
42

OPTIONS

44       -C config-file
45              Use the specified configuration file config-file rather than the
46              default imapd.conf(5).
47
48       -n     Notify  mailbox  owner of deleted messages via email.  This flag
49              is only operable in combination with -r.
50
51       -r     Remove infected messages.
52
53       -s imap-search-string
54              Rather than scanning for viruses, messages matching  the  search
55              criteria will be treated as infected.
56
57       -v     Produce more verbose output
