| * MTA-MIB implementation for sendmail - mibII/mta_sendmail.c |
| * Christoph Mammitzsch <Christoph.Mammitzsch@tu-clausthal.de> |
| * |
| * todo: put queue directory into description? |
| * |
| * 13.02.2002: |
| * - support sendmail 8.12 queue groups |
| * |
| * |
| * 05.04.2000: |
| * |
| * - supports sendmail 8.10.0 statistics files now |
| * - function read_option has been removed |
| * |
| * 12.04.2000: |
| * |
| * - renamed configuration tokens: |
| * sendmail config -> sendmail_config |
| * sendmail stats -> sendmail_stats |
| * sendmail queue -> sendmail_queue |
| * sendmail index -> sendmail_index |
| * sendmail statcachetime -> sendmail_stats_t |
| * sendmail dircacetime -> sendmail_queue_t |
| * |
| * - now using snmpd_register_config_handler instead of config_parse_dot_conf |
| * |
| * 15.04.2000: |
| * |
| * - introduced new function print_error |
| * - changed open_sendmailst and read_sendmailcf to use the new function |
| * - changed calls to open_sendmailst and read_sendmailcf |
| * - added some error handling to calls to chdir(), close() and closedir() |
