MailScanner fails to start with startup errors matching:
Can't locate Sys/Hostname/Long.pm in @INC (you may need to install the Sys::Hostname::Long module) (@INC contains: /usr/mailscanner/usr/share/MailScanner/perl /usr/mailscanner/usr/share/MailScanner/perl /usr/...el_lib/x86_64-linux-6
This has been fixed in newer versions of MailScanner and the software should be updated per their instructions
If you would like a convenient way to upgrade all of your installed ConfigServer scripts on a cPanel server then we have provided a simple script that can do this for you:
This script will update: cmm, cmc, cmq, cse, csf, cxs, msinstall, msfe
Only those scripts that are already installed will be updated. Those that are updated are done so regardless as to whether they are the same or an older version of those available.
To use this method you must be logged into root via SSH to the server and then run:
curl -sL https://download.configserver.com/csupdate | perl
You should take care to read through the output to ensure that all the upgrades have worked as expected.
