If you plan to use CPX on existing E&C accounts, these are some issues you will likely need to address:

• If any domain on your system does not have a virtusertable catchall, a catchall will be created and new virtusertable entries for all users on your system will be created for those domains on your system. That is, if you have users joe , bob, and sal and domains SUBHOST1-DOMAIN.NAME and SUBHOST2-DOMAIN.NAME, the CPX installer will create the following virtusertable entries, if SUBHOST1-DOMAIN.NAME and SUBHOST2-DOMAIN.NAME do not already have catchalls:

  joe@SUBHOST1-DOMAIN.NAME   joe
  joe@SUBHOST2-DOMAIN.NAME   joe
  bob@SUBHOST1-DOMAIN.NAME   bob
  bob@SUBHOST2-DOMAIN.NAME   bob
  sal@SUBHOST1-DOMAIN.NAME   sal
  sal@SUBHOST2-DOMAIN.NAME   sal
  @SUBHOST1-DOMAIN.NAME Error :nouser Unknown user
  @SUBHOST2-DOMAIN.NAME Error :nouser Unknown user
  

  If a domain already has a catchall, no new virtusertable entries for that domain will be created.

• virtusertable entries will NOT be created automatically for entries in the /etc/mail/aliases. Email is first processed by the virtusertable file and then by the aliases file. This means that if you are relying on the absence of a catchall (allowing mail to pass through virtusertable on to the aliases file), mail will not be delivered as you expect. For example, if you have an alias:

  friends:   joe,bob,sal
  

  but no corresponding virtusertable entry that points to the 'friends' alias, mail sent to 'friends@SUBHOST1-DOMAIN.NAME' will now be intercepted by the virtusertable catchall for that domain. To resolve this, add a virtusertable entry:

  friends@SUBHOST1-DOMAIN.NAME    friends
  

• Any changes you might have made directly to /etc/mail/sendmail.cf or /etc/mail/submit.cf will be lost, since those files will be regenerated from their corresponding .mc files ( hostname.name.mc and freebsd.submit.mc , respectively).
