When there are many different connection destination addresses
As you have probably already read, the inquiry destination address is configured using TypoScript constants. However, the disadvantage of this is that if you use multiple locations (with one connection per location), the requests will all go to one address.
Therefore, you have the option of overwriting the inquiry destination addresses in the connections. Simply enter a recipient name and a recipient address in the connection record - if an entry is found in the connection record, it overwrites the TypoScript settings.
