Mercury/32 uses a control file to store the process information, needed for each message, the codes used in the files are as follows.
NOTE: The use of the various codes can change without further notification in future releases of Mercury/32!
| Code |
Description |
| ST: |
Start time
Example: R 020528160331 12 000032 000030 000001
The R says this is a retry, the next string is a date, time line,tells you when it will next be processed. 2005 March 7 09:58:32 . The next one is the number of tries, 3. The structure is critical, the data can be all zeros. |
| FR: |
From field
Example: user@jassing.com
The used from address in simplest format. |
| DF: |
Data file
Example: MO00018F.QDF
Name of the file, the basename is the same for the QCF and QDF files. |
| FL: |
Flags field
Example FL: 2
This field contains bit values that store information about the state of the job. The following values are defined: #define JF_NOFILTER 0x100 // Do not apply filtering to this job
#define JF_EXPIRE 0x200 // Expire the message when writing it
#define JF_SCANNED 0x400 // The message has been externally scanned
#define JF_LOCAL 0x800 // The message was submitted locally
#define JF_VERPJOB 0x1000 // Process this message as a VERP probe
As a general rule, *only* Mercury should modify this field. |
| OS: |
Original Submission
Example: 020528125939
The time the message originally entered the queue. |
| BA: |
Begin address
Example: user@jassing.com
Indicates the beginning of a single delivery element for the message. A "delivery element" is a single address to which the message is addressed, and it has a number of subsidiary fields - in particular an
- ES: "Element status" field
- RI: "Resolver information" field
- DI: "Diagnostic information" field.
- The element always ends with an EA: ("End address") marker.
|
Other fields can be in the file and, when available, a description might follow.
| RI: |
Resolver information
Example: 000.000.000.000 000.000.000.000 000.000.000.000 000.000.000.000
Mercury stores the results of the first five designated mail exchanger hosts for the address in this field. It does a pass through the whole job first, resolving each element, then uses that information on a second pass to group deliveries that are routed via the same mail server. |
| ES: |
Element status
Example: C 020528130415
Mercury uses this field to record the status of individual items within the message; this is how it can determine that a particular address has been successfully delivered on a previous attempt when retrying a message. C is complete, R is a retry and F is failed. |
