annotate man/masqmail.conf.5 @ 340:60bb2dbe2866 0.3.3
In the tests: replaced logname(1) with $LOGNAME
Because logname(1) may not work if it has no controlling terminal.
See: http://aplawrence.com/cgi-bin/printer.pl?arg=/Forum/TonyLawrence8.html
Be it that reason or not, it didn't work on Crux, but $LOGNAME is set.

| 307 The argument will be expanded on delivery time, | |
| 308 you can use variables beginning with a dolloar sign `$', optionally enclosed in curly braces. | |
| 309 Variables you can use are: | |
| 0 | 310 |
| 34 | 311 uid - the unique message id. |
| 312 This is not necessarily identical with the Message ID as given in the Message ID: header. | |
| 0 | 313 |
| 314 received_host - the host the mail was received from | |
| 315 | |
| 34 | 316 ident - the ident, this is either the ident delivered by the ident protocol |
| 317 or the user id of the sender if the message was received locally. | |
| 0 | 318 |
| 319 return_path_local - the local part of the return path (sender). | |
| 320 | |
| 321 return_path_domain - the domain part of the return path (sender). | |
| 322 | |
| 323 return_path - the complete return path (sender). | |
| 324 | |
| 325 rcpt_local - the local part of the recipient. | |

| 327 rcpt_domain - the domain part of the recipient. | |
