On the other daysof the week, however, MailMan has the option of only looking atmessages created or received recently. You choose how many days. Thedefault is to go through the entire MESSAGE file. It is stronglyrecommended that you set this field to something reasonable, like 30to 60 days. (But only if you follow the recommendation to schedulethis option to run daily. Otherwise leave this field blank.)4.303 - AUTOMATIC INTEGRITY CHECK - MailMan gives you the option ofrunning the MAILBOX file portion of the integrity checker (optionXMUT-CHKFIL) before it actually purges the unreferenced messages.The M xref on file 3.7 is used to determine whether a message isreferenced (in someone's basket) or not. If the M xref is messedup, then the purge might delete messages it shouldn't, or leavemessage it should delete. The integrity checker ensures that theM xref is correct. You choose whether to run it or not. The defaultis to run it. The recommendation is to run it. However, if you findthat it is simply taking too long, you may opt not to run it. Ifyou opt not to run it, then it is recommended that you schedule optionXMUT-CHKFIL to run monthly, because globals can and do become corrupted. |
