PICKUP(8) PICKUP(8) [1mNAME[0m pickup - Postfix local mail pickup [1mSYNOPSIS[0m [1mpickup [22m[generic Postfix daemon options] [1mDESCRIPTION[0m The [1mpickup [22mdaemon waits for hints that new mail has been dropped into the [1mmaildrop [22mdirectory, and feeds it into the [1mcleanup[22m(8) daemon. Ill- formatted files are deleted without notifying the originator. This program expects to be run from the [1mmaster[22m(8) process manager. [1mSTANDARDS[0m None. The [1mpickup [22mdaemon does not interact with the outside world. [1mSECURITY[0m The [1mpickup [22mdaemon is moderately security sensitive. It runs with fixed low privilege and can run in a chrooted environment. However, the pro- gram reads files from potentially hostile users. The [1mpickup [22mdaemon opens no files for writing, is careful about what files it opens for reading, and does not actually touch any data that is sent to its pub- lic service endpoint. [1mDIAGNOSTICS[0m Problems and transactions are logged to [1msyslogd[22m(8). [1mBUGS[0m The [1mpickup [22mdaemon copies mail from file to the [1mcleanup[22m(8) daemon. It could avoid message copying overhead by sending a file descriptor instead of file data, but then the already complex [1mcleanup[22m(8) daemon would have to deal with unfiltered user data. [1mCONFIGURATION PARAMETERS[0m The following [1mmain.cf [22mparameters are especially relevant to this pro- gram. See the Postfix [1mmain.cf [22mfile for syntax details and for default values. Use the [1mpostfix reload [22mcommand after a configuration change. [1mContent inspection controls[0m [1mcontent_filter[0m The name of a mail delivery transport that filters mail and that either bounces mail or re-injects the result back into Postfix. This parameter uses the same syntax as the right-hand side of a Postfix transport table. [1mreceive_override_options[0m The following options override [1mmain.cf [22msettings. The options are passed on to the downstream cleanup server. [1mno_address_mappings[0m Disable canonical address mapping, virtual alias map expansion, address masquerading, and automatic BCC recip- ients. Specify this if address mapping etc. are to be done [1mafter [22man external content filter. [1mno_header_body_checks[0m Disable header/body_checks. Specify this if header/body_checks are to be done [1mafter [22man external con- tent filter. [1mMiscellaneous[0m [1mqueue_directory[0m Top-level directory of the Postfix queue. [1mSEE ALSO[0m cleanup(8) message canonicalization master(8) process manager sendmail(1), postdrop(8) mail posting agent syslogd(8) system logging [1mLICENSE[0m The Secure Mailer license must be distributed with this software.
