Modify Account class to handle NULL references This patch modifies the Account class to defer to using the associated domain's tid/ssid/qid fields if the per-instance fields are None/NULL.

Modify SQL update script to accept NULL fields for users The value NULL in the qid/ssid/tid fields of the user table means that the value from the associated domain record should be used instead. This patch modifies the PL/pgSQL functions used by Dovecot and Postfix accordingly.

Cache interpolated destination Instead of running the string modification function for destination interpolation twice, store the result once and use the stored result subsequently.

man: Use example.com in catchallinfo example output.

README: reStructuredText fix: ERROR/3 and WARNING/2.

Enable interpolation of alias destinations This patch modifies the virtual_alias_maps function so that the destination address is parsed for the place holders %n, %d and %=, which are replaced with the localpart, the domain or the full address with '@' replaced by '=' of the queried key. In combination with alias domains, this allows for domain-specific recipients. E.g. given example.org and its alias domain example.com, defining an alias postmaster@example.org → postmaster+%d@example.org will cause mail to postmaster@example.*com* to go to postmaster+example.*com*@example.org.

Add catch-all aliases to README/features

Add catchall subcommands to manpages

Include catch-all count in domaininfo output

Make PL/pgSQL function feed back identity for mailboxes/relocated when there are catchall destinations. Without catchall aliases, if no virtual_alias matches, the query can just return NULL and Postfix will later check mailboxes/relocated for the address to rewrite. However, since virtual aliases are handled long before mailboxes/relocated, a catchall alias would also catch mail to mailboxes and relocated addresses, which we do not want. The way to tell postfix to keep delivering is for the virtual alias map to return the search key itself (identity function). This patch changes the postfix_virtual_alias_maps Pl/pgSQL function to do exactly that, but only if there are catchall destinations defined for the domain in question — otherwise it returns NULL when no match is found.
