From: markus schnalke Date: Mon, 30 Jan 2012 10:03:29 +0000 (+0100) Subject: Rest of the MMDF-style mail drop support removal. X-Git-Tag: mmh-thesis-end~390 X-Git-Url: http://git.marmaro.de/?p=mmh;a=commitdiff_plain;h=684ec30d81e1223a282764452f4902ed4ad1c754 Rest of the MMDF-style mail drop support removal. Only Unix-style (mbox) mail drops are supported now. Their location is in `mailspool', which is reported in the configure summary now. If users like to have different locations, they can use the environment variable MAILDROP or the profile entry MailDrop to overrule the default. From mts.conf, mmdfldir and mmdflfil were removed. msgchk(1) received several cleanups. I touched sbr/m_getfld.c ...
