dns_mx(3) Library Functions Manual dns_mx(3)NAME
dns_mx - look up Mail eXchanger
SYNTAX
#include <dns.h>
int dns_mx(stralloc* out,stralloc* fqdn);
DESCRIPTION
dns_mx looks up MX records for the fully-qualified domain name in fqdn. It puts the MX records into out and returns 0. Each MX record is a
two-byte MX distance (big endian) followed by a -terminated dot-encoded domain name. If the domain does not exist in DNS, or has no MX
records, out will be empty.
If dns_mx has trouble with the DNS lookup or runs out of memory, it returns -1, setting errno appropriately. It may or may not change out.

masqmail.get - masqmail get configuration file
DESCRIPTION
This man page describes the options available for the masqmail get configuration.
OPTIONS
protocol = string
The protocol with which you retrieve your mail. Currently only `pop3' and `apop' are supported. There is no default.
server = string
The server you get your mail from.
port = number
The port number of server to connect to.
Default: 110.
resolve_list = list
Specify the method how the domain of the server is resolved. Possible values are dns_mx, dns_a, byname. For `dns_mx', the domain
is assumed to be an MX pointer to a list of host names, these will be tried each in order (lowest preference value first, equal
preference values in random order). For `dns_a', the domain is assumed to be an A pointer. For `byname', the library function
gethostbyname(3) will be used.
The default is "dns_a;byname". It does not make much sense here to use `dns_mx'.
user = string
Your login name.
pass = string
Your password.
address = address
The address where the retrieved mail should be sent to. It can be any address, but you probably want to set this to a local address
on your LAN.
return_path = address
If set, masqmail sets the return path to this address. Bounces generated during further delivery will be sent to this address. If
unset, masqmail looks for the Return-Path: header in the mail, if this does not exist it uses the From: address and if this fails,
postmaster will be used.
It is in most cases not useful to set this to the same address as the `address' option as this may generate multiple bounces. post-
master is recommended.
do_keep = boolean
If you want to keep your mail on the server after you retrieved it, set this to true. It is recommended that you also set do_uidl,
otherwise you will get the mail again each time you connect to the server. Masqmail does not check any headers before it retrieves
mail, which may mark it as already fetched. Note that this behaviour is different to that of fetchmail. The default is false.
do_uidl = boolean
If set, masqmail keeps a list of unique IDs of mails already fetched, so that they will not be retrieved again. Default is false.
do_uidl_dele = boolean
If set, and do_uidl is also set, MasqMail sends a delete (DELE) command to the server for each message uid in the uid listing at the
beginning of the session. This prevents mail to be left on the server if masqmail gets interrupted during a session before it can
send the QUIT command to the server. Default is false.
max_size = numeric
If set to a value > 0, only messages smaller than this in bytes will be retrieved. The default is 0.
max_count = numeric
If set to a value > 0, only max_count messages will be retrieved. The default is 0.
max_size_delete = boolean
If max_size > 0 and do_uidl_dele is set, delete messages that are larger than max_size on the server WITHOUT retrieving them. Be
careful with this option.
Default: false
wrapper = command
If set, instead of opening a connection to a remote server, command will be called and all traffic will be piped to its stdin and
from its stdout. Purpose is to tunnel ip traffic, e.g. for ssl.
Example for ssl tunneling:
wrapper="/usr/bin/openssl s_client -quiet -connect pop.gmx.net:995 2>/dev/null"
