At boot i get this message from amavis services :
[warn] Not starting amavisd-snmp-subagent - edit /etc/default/amavisd-snmp-subagent to enable it ... (warning).

And after editing the file and activating this service i get :

[....] Restarting amavis snmp subagent (bdb version): amavisd-snmp-subagentCan't locate NetSNMP/OID.pm in @INC (you may need to install the NetSNMP::OID module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.24.1 /usr/local/share/perl/5.24.1 /usr/lib/x86_64-linux-gnu/perl5/5.24 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.24 /usr/share/perl/5.24 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base) at /usr/sbin/amavisd-snmp-subagent line 130.

failed!

How to solve this issue ?
This issue have been around since i installed iredmail , never worked but it is still active in init.d

How much important it is and what is its role in the server ?

I dont have any issues receiving emails or sending them , however it makes me wonder why was this service installed if it is not working ?

Thank you
