Exim can write to a bunch of different mailbox formats, MBOX and MBX being two of them. The ebuild assumes that if -mbox is set (the default), then MBX should be disabled. This is an erroneous assumption as the two formats have nothing to do with one another. Further, MBX is widely used by uw-imap servers (it is the recommend format). Recommend either renaming -mbox to -mbx to disambiguate it, or get rid of it (since -mbox doesn't get rid of exim's mbox format). See for a description about the different mailbox types. http://tinyurl.com/ckfgz The offending part of exim-4.54.ebuild (line 106): if use mbox; then sed -i "s:# SUPPORT_MBX=yes:SUPPORT_MBX=yes:" Makefile fi Reproducible: Always Steps to Reproduce: 1. emerge exim 2. exim -C /etc/exim/exim.conf -bV | grep -i mbx Actual Results: No output, exim doesn't have MBX transport. Expected Results: Exim should have MBX support by default, and the -mbox flag should either be renamed to -mbx or dropped altogether.
This should be fixed in exim 4.60, please confirm
No response, assuming fixed.
