1(Version 8.13 of 12/30/93) 2 3Key: 4 X -- extension (user visible change) 5 B -- bug fix 6 S -- security fix 7 E -- enhancement to existing algorithm 8 9X **** 8 -> 7 bit MIME conversion. 10 11E **** Change NoReturn to be an envelope flag. [8.7] 12 13X **** Add M_NOLOOPBACKCHK (k) mailer flag to turn off check of name in 14 HELO command. [8.8] 15 16X **** Merge Sun changes. [8.7] 17 18X **** Macro giving size of the message in bytes. 19 20X **** Create a "service switch" abstraction that will interface with 21 Sun NSS, Ultrix /etc/svc.conf, etc. This will allow you to 22 turn off DNS entirely, a la ``OIoff''. [8.7] 23 24X **** Should have new mailer flags to override LocalMailer stuff: 25 - M_ALIASABLE (A) -- can use as the LHS of an alias. 26 - M_HASPWENT (w) -- should have a /etc/passwd entry. If not found 27 there, implies user unknown. Also implies .forward and UDB 28 searching, search for |, /, and :include:, etc.). 29 - Actually, UDB searching and |, /, and :include: mapping should 30 probably be on another flag. (Cannot be 'l' for back compat 31 reasons.) 32 - Need for $@host part of triple and Return-Receipt-To: processing 33 should also be split apart. 34 [8.8] 35 36X **** Mailer flag to override MX lookups. 37 38E **** Fix parseaddr to return a dummy mailer with QBADADDR set for 39 all cases except null input; change calls to be more sceptical 40 about the return value, checking this bit instead of just 41 checking for == NULL. (Eric Wassenaar) [8.7] 42 43X **** Run time configurable locking -- e.g., compile in HASFLOCK and 44 HASLOCKF, and then choose at runtime between these. 45 46E **** Move delivery forking from sendenvelope to sendall so that 47 the connection cache works between split envelopes, and to 48 avoid a flurry of processes should you be sending to lots of 49 sub-lists. 50 51X **** Add uucp-bang mailer that strips off any domain name from 52 the envelope recipient address first; this is for use in 53 mailer table entries. 54 55X **** "quote" map (inverse of dequote). Lets you turn node::user 56 into "node::user"@DECNET.gateway 57 58X **** Named rulesets. 59 60X *** Mailer flag that does a "ping" equivalent -- if it fails, wait 61 30 seconds and try again (for dialup PPP connections). Could 62 just try the connection and then immediately retry on some 63 kinds of failures. 64 65X *** Create a macro that has message size. 66 Peter Wemm <peter@DIALix.oz.au> 67 68E *** Dynamically allocate MAXNAME buffers for headers. 69 70E *** Dynamically allocate "line" buffer in readaliases(). 71 72X *** Add ability to disable Return-Receipt-To: on a privacy flag. [8.8] 73 74X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 75 76X *** Runtime option to enable/disable IDENT protocol. 77 78E *** Don't send ErrMsgFile to postmaster bounces. (Josh Smith, 79 josh@osiris.ac.hmc.edu). 80 81X *** Add "user" map to look up a user name via getpwnam -- so that 82 non-local names can be forwarded to another site. [8.8] 83 84E *** Have daemons that start up check the alias database for 85 correctness and auto-rebuild if necessary. This is to handle 86 the case of a system crash during an alias database rebuild. 87 88E *** Eliminate E qf line and e_errorqueue; use e_errorsto a la 89 e_receiptto. This simplifies and gives symmetry. (Eric 90 Wassenaar) 91 92B *** Fix syslog buffer overflow problems. 93 94X *** DECNET_RELAY support in configs. 95 96X ** "E" configuration line that sets environment variables. 97 98E ** Change listen() high-load backoff to accept and issue a 4xx 99 message so that it responds more quickly. 100 101E ** Change "/usr/tmp/dead.letter" to be based on _PATH_VARTMP. 102 103B ** Commas in NAME envariable cause problems (Peter Wan 104 <peter@cc.gatech.edu>). Merge with suggestions to use 105 MIME-format for 8-bit characters? 106 107E ** Save address information that comes back as the "additional 108 records" part of an MX lookup, to avoid additional name server 109 attempts. If there is an MX record without an additional A 110 record, delete it (this avoids a problem with misconfigured 111 DNS situations). 112 113X ** Allow a way to extend the $Z macro with local configuration 114 information. 115 116X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 117 118X ** Allow /address in -bt mode to expand address through ruleset 0, 119 aliases, etc. and display results. [8.8] 120 121X ** "R mailer address" in -bt mode does remotename on address. 122 123E ** Adjust "infinite loop in rule" code to handle entire ruleset 124 (Code from Michael Corrigan). 125 126E ** Allow :include: from command line (not SMTP) to assist in 127 "personal list" management -- i.e., creating lists that 128 cannot be EXPNed. 129 130X ** Database (keyed lookup) auto-rebuild. 131 132X ** Find a good test suite and include in the distribution. 133 134S ** You can use symbolic links to point into protected directories. 135 (AEJ) 136 137X ** Extend OI to allow separate settings for canonification, MX, and A 138 lookups. [8.8?] 139 140X ** Add $!x class to match any number of words not in class x. (KRE) 141 142X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 143 144X ** Add "bestmx" map -- returns "best MX host" for this address. 145 Allows you to do automatic detection of when you are the best 146 MX for a given address. [8.7?] 147 148X ** Extend makemap to "gather" values -- i.e., merge entries that 149 have the same keys. [8.8] (BCX) 150 151E ** Allow error messages on individual addresses in the qf file. 152 (BCX) 153 154X ** Multi-character option names. [9.1] 155 156X ** User database extensions for mailing lists: 157 list:precedence -- Precedence: value for new message 158 list:envelopefrom -- envelope "from" value for new message 159 others? [8.8] 160 161B ** Restore `T' line to eliminate X-Authentication-Warning: at 162 inappropriate times. (Christophe Wolfhugel) 163 - T could become a shorthand for Ct -- i.e., create a new 164 predefined class. 165 - Eliminate "<user> set sender to <address>" message entirely? 166 (this is the workaround) 167 168B ** Return-Path: header should have <> added if not already there. 169 170X ** Add heuristic to determine if other end is a sendmail; use 171 that to decide whether or not to honor F=I mailer flag. 172 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 173 174X ** Automatically drop into MIME mode if you have a full name 175 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 176 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 177 178X ** -b? flag to read a header and show you what it will look like 179 after all rewriting for an indicated address. 180 181E ** Log $u in logsender() (for=<someaddress>). 182 183X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 184 185X * -V flag to print state of all (?) compilation flags. 186 187X * Handle Expires: header field (if still in queue). 188 189X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 190 (Bruce Lilly <blilly!bruce@uu.psi.com>) 191 192X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 193 194B * EXPN adds @domain to all mailers, including prog. Is this right? 195 [Bob Henry] 196 197B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 198 199E * Change body put code to time out around individual puts. This will 200 make the timeout algorithm more responsive and more resilient. 201 Unfortunately, it's also a pain in the butt. 202 203X * Some way to relay unfound local users to another site. 204 205X * Disable all default RW sets except mailer-specific? 206
