97 | /* See local README for interface description. The query in the "keystring" may |
98 | consist of a number of parts. | |
99 | ||
8e669ac1 PH |
100 | (a) If the first significant character is '>' then the next character is the |
101 | separator character that is used when multiple records are found. The default | |
7bb56e1f PH |
102 | separator is newline. |
103 | ||
0d0c6357 NM |
104 | (b) If the next character is ',' then the next character is the separator |
105 | character used for multiple items of text in "TXT" records. Alternatively, | |
106 | if the next character is ';' then these multiple items are concatenated with | |
107 | no separator. With neither of these options specified, only the first item | |
8ee4b30e PP |
108 | is output. Similarly for "SPF" records, but the default for joining multiple |
109 | items in one SPF record is the empty string, for direct concatenation. | |
0d0c6357 NM |
110 | |
111 | (c) If the next sequence of characters is 'defer_FOO' followed by a comma, | |
ff4dbb19 PH |
112 | the defer behaviour is set to FOO. The possible behaviours are: 'strict', where |
113 | any defer causes the whole lookup to defer; 'lax', where a defer causes the | |
114 | whole lookup to defer only if none of the DNS queries succeeds; and 'never', | |
115 | where all defers are as if the lookup failed. The default is 'lax'. | |
116 | ||
0d0c6357 | 117 | (d) If the next sequence of characters is a sequence of letters and digits |
8e669ac1 | 118 | followed by '=', it is interpreted as the name of the DNS record type. The |
ff4dbb19 | 119 | default is "TXT". |
7bb56e1f | 120 | |
0d0c6357 | 121 | (e) Then there follows list of domain names. This is a generalized Exim list, |
8e669ac1 | 122 | which may start with '<' in order to set a specific separator. The default |
7bb56e1f | 123 | separator, as always, is colon. */ |
