Fileinto, nofileinto channel options

Sieve filter fileinto action channel options
The  channel option, currently only especially meaningful for channels delivering into the Messaging Server Message Store (that is,    and   channels),  specifies how to alter an address when a  Sieve filter   " " action is  applied. is the default, and means that a Sieve filter " " action has no address-modifying meaning for that destination channel.

For  channels, the usual  usage is  fileinto $U+$S@$D meaning that the folder name should be inserted as a subaddress into the original address, replacing any originally present subaddress. (The default value for the FILEINTO ims-ms-channel-specific option then results in the   channel interpreting that subaddress as a request for folder delivery.)

For  channels,  the usual usage is  fileinto @$4O:$U+$S@$D (where note that in  the   is the capital or majuscule letter "o", not the numeral zero 0). The effect is that the explicit source route to the mailhost should be preserved if present, and the foldername should be inserted as a subaddress into the original address, replacing any originally present subaddress.

The Message Store delivery code normally considers any "trusted" subaddress present on a recipient address as a request to deliver directly into the correspondingly named folder. (This can be overridden for the  channel by disabling the FILEINTO ims-ms-channel-specific option.)  Application of the   channel option  also sets a  bit in the message envelope that means that for Message Store delivery "trust this subaddress as a folder name for delivery purposes". So when the  channel option is applied on an    channel or a   channel,  subaddresses added due to a Sieve filter  " " action will cause folder delivery. Note that unless a subaddress has been added/replaced due to such a Sieve " " action and the   channel option&#x27;s resulting setting of the proper message envelope bit, any other subaddress will not normally be considered as a valid request for folder delivery---not unless the IMAP post ACL (RFC 4314, IMAP4 Access Control List (ACL) Extension) has been set on that folder in the Message Store.
