Dear All,

Customer is running 2 servers with this configuration :

1st server : ldap / mta / store / snmp
2nd server : mta / store

both of them are 5.0.9 open source edition, and plan to upgrade to 5.0.12 OE.

can anyone advice what's the step to upgrade? I've read the Release note, and it's saying : ldap -> mta -> mail store

How can I do that in my environment?

any advice ?
