mailfilter - Filters e-mail, gets rid of spam SYNOPSIS
mailfilter [OPTION]... DESCRIPTION
Mailfilter is a very flexible utility to get rid of unwanted spam mails, before having to go through the trouble of downloading them into the local computer. It offers support for one or many POP accounts and is especially useful for dialup connections via modem, ISDN, etc. Mailfilter connects to any POP mail box and compares part of its content to a set of user defined filter rules. That way the spam gets deleted directly on the mail server. With Mailfilter you can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste. Rules are Regular Expressions, so you can make use of familiar options from other mail delivery programs such as procmail(1) for example. RETURN VALUE
The mailfilter program normally returns 0 but -1 if an error occurs. However, if it has been invoked with the return-value command line switch, it gives back a positive integer in case there are messages on the POP server. Empty POP accounts would then result in a return value of 0. Using the switch, mailfilter can be embedded into a shell script more easily. CONFIGURATION
The behaviour of Mailfilter is controlled by command-line options and a configuration file. The program will not start without it. Example configurations can be looked up in the mailfilterex(5) man page, in the INSTALL document or inside the doc/ directory of the Mailfilter distribution. By default Mailfilter tries to read $HOME/.mailfilterrc to get all its settings from. This is the place where all changes should be made, unless it is explicitly specified otherwise. A comprehensive list of all supported options and keywords can be found in the mailfilterrc(5) man page. OPTIONS

MSGCHK(1) [nmh-1.5] MSGCHK(1) NAME
msgchk - check for messages SYNOPSIS
msgchk [-date | -nodate] [-notify all/mail/nomail ] [-nonotify all/mail/nomail ] [-host hostname] [-user username] [-sasl] [-saslmech mech- anism] [-snoop] [users ... ] [-version] [-help] DESCRIPTION
The msgchk program checks all known mail drops for mail waiting for you. For those drops which have mail for you, msgchk will indicate if it believes that you have seen the mail in question before. The -notify type switch indicates under what circumstances msgchk should produce a message. The default is -notify all which says that msgchk should always report the status of the users maildrop. Other values for `type' include `mail' which says that msgchk should report the status of waiting mail; and, `nomail' which says that msgchk should report the status of empty maildrops. The -nonotify type switch has the inverted sense, so -nonotify all directs msgchk to never report the status of maildrops. This is useful if the user wishes to check msgchk's exit status. A non-zero exit status indicates that mail was not waiting for at least one of the indicated users. If msgchk produces output, then the -date switch directs msgchk to print out the last date mail was read, if this can be determined. Using POP msgchk will normally check all the local mail drops, but if the option "pophost:" is set in the mts configuration file "mts.conf", or if the -host hostname switch is given, msgchk will query this POP service host as to the status of mail waiting. The default is for msgchk to assume that your account name on the POP server is the same as your current username. To specify a different username, use the `-user username' switch. When using POP, you will normally need to type the password for your account on the POP server, in order to retrieve your messages. It is possible to automate this process by creating a ".netrc" file containing your login account information for this POP server. For each POP server, this file should have a line of the following form. Replace the words mypopserver, mylogin, and mypassword with your own account information. machine mypopserver login mylogin password mypassword This ".netrc" file should be owned and readable only by you. For debugging purposes, there is also a switch -snoop, which will allow you to watch the POP transaction take place between you and the POP server. If nmh has been compiled with SASL support, the -sasl switch will enable the use of SASL authentication. Depending on the SASL mechanism used, this may require an additional password prompt from the user (but the ".netrc" file can be used to store this password). The -saslmech switch can be used to select a particular SASL mechanism. If SASL authentication is successful, inc will attempt to negotiate a security layer for session encryption. Encrypted traffic is labelled with `(encrypted)' and `(decrypted)' when viewing the POP transaction with the -snoop switch. FILES
