Hi is it possible to use the postfix "recipient_delimiters" option to specify multiple values. I'm migrating from a qmail install so have currently used minus (-) to delimit my addresses but want to support the postfix (+) method as well. However, if I change the main.cf to use recipient_delimiters, then when I send an email using either of the delimiters I get an "unknown user in virtual mailbox table" error. Using recipient_delimiter with either value works fine.

Am I missing something or is this config not supported?

Thanks

John
