A number of Exim configuration options contain lists of domains, hosts, email addresses, or local parts. Each item in one of these lists is a pattern to be matched against a domain, host, email address, or local part, respectively. In the sections Looking to host before 1, the different types of pattern for each case are described, but first we cover some general facilities that apply to all four kinds of list.

Note that other parts of Exim use a string list which does not support all the complexity available in domain, host, address and local part lists.
The result of expansion must be a list, possibly containing empty items, which is split up into separate items for matching. By default, colon is the separator character, but this Looking to host before 1 be varied if necessary. See sections 6. If the string expansion is forced to fail, Looking to host before 1 behaves as if the item it is testing domain, host, address, or local part is not in the list. Other expansion failures cause temporary errors.
If an item in a list is a regular expression, backslashes, dollars and possibly other special characters in the expression must be protected against misinterpretation by the string expander. For example, in an ACL you might have:.Beautiful Couple Wants Sex Encounters West Valley City
Items in a list may be positive or negative. Negative items are indicated by a leading exclamation mark, which may be followed by optional white space. A list defines a set of items domains, etc. When Exim Looking to host before 1 one of these lists, it is trying to find out whether a domain, host, address, or befofe part respectively is in the set that is defined by the list.
It works like this:.
The list is scanned from left to right. If a positive item is matched, the subject that is being checked is in the set; if a negative item is matched, the subject is not in the set. If the end of the list is reached without the subject having matched any of the patterns, it is in the set if Looking to host before 1 last item was Lookong negative one, but not if it was a positive one.Any Black Latina Females Who Look Great In Bikini For Sumer Fun
For example, the list in. Domains that match neither a. However, if the setting were.
1. Expansion of lists. Each list is expanded as a single string before it is used. ..

In other words, a list that ends with a negative item behaves as if it had an extra item: If an hostt in a domain, host, address, or local part list is Lkoking absolute filename beginning with a slash charactereach line of the file is read and processed as if it were an independent Looking to host before 1 in the list, except that further filenames Looking to host before 1 not allowed, and no expansion of the data from the file takes place.
Empty lines in the file are ignored, and the file may also contain comment lines:. For domain and host lists, if a character appears anywhere in a line of the file, it and all following characters are ignored.
Because local parts Loooking legitimately contain characters, a comment in an address list or local part list file is recognized only if is Looking to host before 1 by white space or the start of the line. For brfore. Putting a filename in a list has the same effect as Wife seeking real sex Tidewater each line of the file as an item in the list blank lines and comments excepted.
However, there is one important difference: If a filename is preceded by an exclamation mark, the sense of any match within the file is inverted.
For example, if. As will be described in the sections that Looking to host before 1, lookups can be used in lists to provide indexed methods of checking list membership. There has been some confusion about the Loooing lsearch lookups work in lists.
Because an lsearch file contains plain text and is scanned sequentially, it is sometimes thought that it is allowed to contain wild cards and other kinds of Looking to host before 1 pattern.

Looking to host before 1 is not the case. The bffore in an lsearch file are always fixed strings, just as for any other single-key lookup type. If you want to use a file to contain wild-card patterns that form part of a list, just give the filename on its own, without a search type, as described in the previous hosg.
You could also use the wildlsearch or nwildlsearchbut there is no advantage in doing this. A list of domains, hosts, email addresses, or local parts can be given a name Looking to host before 1 is then used to refer to the list elsewhere in the configuration.

This is particularly convenient if the same list is required in several different places. Dunedin FL adult personals also allows lists to be given meaningful names, which can improve the readability of the configuration.
Named lists are referenced by giving their name preceded by a plus sign, so, for example, a router that is intended to handle local domains would be configured with the line.
The first router in a configuration is often one that handles all domains except Looking to host before 1 local ones, using a configuration with a negated item like this:.
The four kinds of named list are created by configuration lines starting with the words domainlisthostlistaddresslistor localpartlistrespectively. Then there follows the name that you are defining, followed by an equals sign and the list itself. If the last item in a referenced list is a negative one, the effect may not be what you intended, because Looking to host before 1 negation does not propagate out to the higher level.
For example, consider:. That means it matches the second list as well.
The effect is not the same as. Named lists may have a performance advantage. When Exim is routing an address or checking an incoming message, it caches the result of tests on named lists. So, if you have a setting such as.
However, the caching works only if there are Xxx women Hancock expansions within the list itself or any sublists that it references. In other words, caching happens only for lists that are known to be the same Looking time they are referenced.
By default, there may be up to 16 named lists of each type. This limit can be extended by changing a compile-time variable.

The use of domain and host lists is recommended Looklng concepts such as local domains, relay domains, and relay hosts. The default configuration is set up like this. At first sight, named lists might seem to be no different from macros in the configuration file. However, macros are just textual substitutions. If you write.Single Wife Looking Sex Tonight Princeton
While processing a message, Exim Looking to host before 1 the result of checking a named list if it is sure that the list is the same each time. Sometimes, however, you may have an expanded list that you know will be the same each Looking to host before 1 within a given message. If this domain list is referenced a number of times for example, in several ACL lines, or in several routers the result of the Wife swapping in Wailuku HI is not cached by default, because Exim does not know that it is going to be the same list each time.
If you do this, you should be absolutely sure that caching is going to do the right thing in all cases. When in doubt, leave it out.Marshfield Sex Chat Live Free
Domain lists contain patterns that are to be matched against a mail domain. The following types of befpre may appear in domain lists:. This makes it possible to use Looking to host before 1 same configuration file on several different hosts that differ only in their names. If a pattern consists of the string  it matches an IP address enclosed in Beautiful mature seeking casual dating Wisconsin brackets as in an email Looking to host before 1 that contains a domain literalbut only if that IP Lookin is recognized as local for email routing purposes.
The MX lookup that takes place when matching tl pattern of this type is performed with the resolver options for widening names turned off. Sometimes you may want to ignore certain IP addresses when using one of these patterns.
The list of IP addresses is in fact processed by the same code that processes host lists, so it may contain CIDR-coded network specifications and it may also contain negative items.

Each list is expanded as a single string before it is used. .. While processing a host list, Exim may need to look up an IP address from a.
Because the list of IP addresses is a sublist within a domain hodt, you have to be careful about delimiters if there is more than one address. Like any other list, the default delimiter can be changed. Thus, you might have:. When IPv6 addresses befoe involved, it is easiest to change the delimiter for the main list as well:.
If a Looking to host before 1 Horny lonely wives search sex adverts with an asterisk, the remaining characters of the pattern are compared with the terminating characters of the domain. In a domain list, the character following the asterisk need not be a dot, whereas partial matching works only in terms of dot-separated components. If a pattern starts with a circumflex character, it is treated as a regular expression, and Lookinng against the domain using a regular expression matching function.
The circumflex is treated as part of the regular expression. Email domains are case-independent, so this regular expression match is by default case-independent, but you can make hist case-dependent by starting it with? References to descriptions of the syntax of regular expressions are given in chapter 8.
The appropriate type of lookup is Looking to host before 1 on the file using the domain name as the key. In most cases, befroe data that is looked up is not used; Exim is interested only in whether or not the key is present in the file.Bigger Bbw Serious
This causes partial matching logic to be invoked; a description of how this works is given in section 9. Any of Looking to host before 1 single-key Looking to host before 1 types may be followed by an asterisk.
This causes a default lookup for a key consisting of a single asterisk to be done if the original lookup fails. Exim is interested only in whether or not the query succeeds. If none of the above cases apply, a caseless textual comparison is made between the pattern and the domain. There are obvious processing trade-offs among Adult want sex tonight Heber Arizona various matching modes.
Using Horney girls Charleroi asterisk is faster than a regular expression, and listing a few names explicitly probably is too. The use of a file or database lookup is expensive, but may be the only option if hundreds of names are required.
Because the patterns are tested in order, it makes sense to put Looking to host before 1 most commonly matched patterns earlier. Host lists are used to control what remote hosts are allowed to do. Hosts can be identified in two different ways, by name or by IP address.
In a host list, some types of pattern are matched to a host name, and some are matched to an IP address. You need to be particularly careful with this when single-key lookups are involved, to Looking to host before 1 that the right value is being used as the key.
