835 .SH CATCH-ALL SUBCOMMANDS

   836 .SS catchalladd (caa)

   837 .BI "vmm catchalladd" " domain destination ..."

   838 .PP

   839 This subcommand allows to specify destination addresses for a domain, which

   840 shall receive mail addressed to unknown local parts within that domain. Those

   841 catch-all aliases hence "catch all" mail to any address in the domain (unless

   842 a more specific alias, mailbox or relocated entry exists).

   843 .PP

   844 WARNING: Catch-all addresses can cause mail server flooding because spammers

   845 like to deliver mail to all possible combinations of names, e.g. to all

   846 addresses between abba@example.org and zztop@example.org.
