Unless I map user.s...@example.com to someuser or at least to someu...@example.com how else will cyrus-imapd identify the mailbox? I cannot recall ever providing cyrus itself with a map of allowable email addresses in RFC821 format.

Will any of these placed in virtual_aliases will have that effect where example.com is in virtual_mailbox_domains? 1. some.u...@example.com someuser@$myhostname or 2. some.u...@example.com someuser >> >> It seems that virtual_mailbox_maps essentially duplicates the keys >> of virtual_alias_maps. > > Users listed in virtual_mailbox_maps should not be duplicated in > virtual_alias_maps.

If I list these in virtual_aliases_maps where the value portion of the mapping is unused and I do not put these entries in virtual_aliases and map them to someuser then how does cyrus-imap perform the mapping? Where does it get its information? -- *** E-Mail is NOT a SECURE channel *** James B.
