Greeting messages can be set by both the LDAP attribute mailDomainWelcomeMessage and the configutil parameter gen.newuserforms. The order in which a message will get chosen, with the top one having the highest preference, is shown below:
mailDomainWelcomeMessage;lang-user_prefLang mailDomainWelcomeMessage;lang-domain_prefLang mailDomainWelcomeMessage;lang-gen.sitelanguage mailDomainWelcomeMessage gen.newuserforms;lang-"$user-prefLang" gen.newuserforms;lang-"$domain-prefLang" gen.newuserforms;lang-"$gen.sitelanguage" gen.newuserforms
The algorithm works as follows: if there are no domains (or there are, but there is no per domain welcome message provisioned for them), a welcome message is configured with the gen.newuserforms parameter, if specified. If a user has a preferred language (set with the preferredlanguage LDAP attribute) and gen.newuserforms;lang-user_prefLang is set, the user will receive that welcome message at the time of their first log in to the server. If gen.newuserforms;lang-gen.sitelanguage is set, and preferredlanguage is not set, but the site language is set (using gen.sitelanguage parameter), user will receive that message. If no language tag parameter is set and a untagged gen.newuserforms is set, then that message will be sent to the user. If none of the values are set, user will not receive any welcome message.
If the user is in a domain, then similar to the discussion above, the user might receive one of mailDomainWelcomeMessage;lang-xx, depending on which one is available in the list and in the order given.
Example: Domain is siroe.com. The domain preferred language is German (de). But the new user in this domain has preferred language of Turkish (tr). Site language is English. The following values are available (mailDomainWelcomeMessage are attributes of the domain siroe.com):
mailDomainWelcomeMessage;lang-fr mailDomainWelcomeMessage;lang-ja gen.newuserforms;lang-de gen.newuserforms;lang-en gen.newuserforms
According to the algorithm, the message sent to user will be gen.newuserforms;lang-de.
