<p class=MsoNormal>Hi MailScanner users,<o:p></o:p></p>
<p class=MsoNormal>I have a fresh-built Centos 5 box, on which I have compiled
Perl 5.10.0 from source, and MailScanner 4.66.5 installed from RPM. Perl was upgraded
after MailScanner was installed. I know RPM should be an “all or nothing”
decision <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The problem I have is that I noticed that the processes
MailScanner was forking when starting where dying instantly, and when running
MailScanner --lint, it dies with the error:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>“Can't use string ("/var/spool/mqueue.in")
as an ARRAY ref while "strict refs" in use at /usr/sbin/MailScanner
line 441.”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>“/var/spool/mqueue.in” is not my incoming
directory, “/var/spool/exim.in” is, and the mqueue.in directory
does not exist. The correct incoming directory is set in /etc/MailScanner/MailScanner.conf.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Using “locate MailScanner |xargs grep “mqueue.in”
and some luck, I managed to find that the mqueue reference was coming from “/usr/lib/MailScanner/MailScanner/ConfigDefs.pl”,
so I hacked the “inqueuedir” variable to point at the correct directory,
but it doesn’t change the error, apart from the path within string().<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My first thought was a missing perlmod dependency for MailScanner
after the upgrade of Perl, however MailScanner -v shows:<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>before it dies and writes out the error about line 1385,
however I am not sure what this means or even if it is relevant, and the references
I can find for “perl +’Inappropriate ioctl for device’”
on the web don’t really help. Locking method in the MailScanner.conf is
set to posix, as Exim is in use. Perl was built to use perlio method for locks.
I’m wondering whether the Filesys module is doing or expecting something which
MailScanner can’t/isn’t handle/ing?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any hints would be greatly appreciated, but if the answer is
“don’t use perl 5.10.0 yet” or “you must have screwed
up your compile of perl”, that’s fine I’ll roll back, but I
am keen to try and fix this problem, as the reason for the upgrade was to see
whether the perl core improvements in 5.10.0 made much of a difference to
MailScanner performance in comparison to our live boxes running 5.8.0.<o:p></o:p></p>
