 From 'man mail' on CentOS:

 -a      Specify additional header fields on the command line such as "X-Loop: foo at bar" 
         etc.  You have to use quotes if the string contains spaces.  This
         argument may be specified more than once, the headers will then be concatenated.

This should do:

mail -a From:someuser at system.ucd.ie -s "$subject" "$adminEmail" < $mailLog
