1(Version 8.28 of 12/14/94) 2 3Key: 4 X -- extension (user visible change) 5 B -- bug fix 6 S -- security fix 7 E -- enhancement to existing algorithm 8 9 10X **** Multiple queues. 11 12X **** Merge Sun changes. [8.7] 13 14E **** Fix parseaddr to return a dummy mailer with QBADADDR set for 15 all cases except null input; change calls to be more sceptical 16 about the return value, checking this bit instead of just 17 checking for == NULL. (Eric Wassenaar) [8.7] 18 19X **** Run time configurable locking -- e.g., compile in HASFLOCK and 20 HASLOCKF, and then choose at runtime between these. 21 22B **** Aliases with .REDIRECT fail during newaliases if the "n" flag 23 is given. Problem is, sometimes you want them to, sometimes 24 you don't. Perhaps two flavors of "error" mailer? 25 26B **** Calls to gethostbyname with a trailing dot fail if you are 27 not running DNS. 28 29X **** Add uucp-bang mailer that strips off any domain name from 30 the envelope recipient address first; this is for use in 31 mailer table entries. 32 33X **** "quote" map (inverse of dequote). Lets you turn node::user 34 into "node::user"@DECNET.gateway 35 36X **** Named rulesets. 37 38? **** Should $( [1.2.3.4] $) convert the address to a name? 39 40E *** Have recipient lines rewritten by the user database. 41 42E *** Arrange to run queue jobs as the owner of that queue file. This 43 probably requires forcing a fork in order to be able to completely 44 restore the uid/gid portably without leaking out root privileges. 45 46E *** Long term host status -- store host status on disk for sharing 47 between runs. 48 49X *** Extend I option to allow setting of retry and timeout values. 50 drl@vuse.vanderbilt.edu (David R. Linn). 51 52X *** Total connection cache lifespan timeout -- a way to give a 53 timeout on connections regardless of whether they are active 54 or not. For single threaded servers such as Microsoft SMTP 55 gateway. Douglas Anderson <dlander@afterlife.ncsc.mil>. 56 57X *** Mailer flag that does a "ping" equivalent -- if it fails, wait 58 30 seconds and try again (for dialup PPP connections). Could 59 just try the connection and then immediately retry on some 60 kinds of failures. 61 62X *** Create a macro that has message size. 63 Peter Wemm <peter@DIALix.oz.au> 64 65E *** Dynamically allocate MAXNAME buffers for headers. 66 67E *** Dynamically allocate "line" buffer in readaliases(). 68 69X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 70 71E *** Don't send ErrMsgFile to postmaster bounces. (Josh Smith, 72 josh@osiris.ac.hmc.edu). 73 74E *** Have daemons that start up check the alias database for 75 correctness and auto-rebuild if necessary. This is to handle 76 the case of a system crash during an alias database rebuild. 77 78E *** Eliminate E qf line and e_errorqueue; use e_errorsto a la 79 e_receiptto. This simplifies and gives symmetry. (Eric 80 Wassenaar) 81 82X *** DECNET_RELAY support in configs. 83 84X *** -wN command line flag to set the width of mailq output. 85 (Allan Johannesen) 86 87E *** Move mailertable lookup after UUCP-specific class checks? 88 (Kimmo Suominen <kim@tac.nyc.ny.us>) 89 90E *** Users in more than one list with different owners get duplicate 91 deliveries -- maybe just assign them arbitrarily to one 92 envelope or the other? 93 94X ** Make MAXBADCOMMANDS run time configurable. 95 96E ** Allow mailertable entries of the form ``error:message''. 97 98X ** Have .forward files re-queue if the home directory isn't 99 accessible? On some option... 100 (Q.G.Campbell@newcastle.ac.uk) 101 102X ** Have local delivery queue if NIS is down? On some option... 103 (Q.G.Campbell@newcastle.ac.uk) 104 105E ** Have nullclient configuration resolve local names to the local 106 mailer and then redirect them in ruleset 5; this allows you to 107 redirect root differently depending on the client. It's not 108 clear this is really a good idea though. 109 110E ** Move CurHostAddr into mci struct, and make CurMCI variable 111 point to this, so that logging will give the correct address 112 instead of (0) for cached connections. Motonori Nakamura. 113 114X ** Allow use of a generalized network service for aliasing? 115 How would the protocol be defined? 116 James Gritton <gritton@byu.edu>. 117 118E ** Make "local configuration error" a temporary failure? 119 (add EX_CONFIG to the markfailure list) 120 121X ** (sigh) BSMTP. 122 123X ** "E" configuration line that sets environment variables. 124 125E ** Change listen() high-load backoff to accept and issue a 4xx 126 message so that it responds more quickly. 127 128E ** Change "/usr/tmp/dead.letter" to be based on _PATH_VARTMP. 129 130B ** Commas in NAME envariable cause problems (Peter Wan 131 <peter@cc.gatech.edu>). Merge with suggestions to use 132 MIME-format for 8-bit characters? 133 134E ** Save address information that comes back as the "additional 135 records" part of an MX lookup, to avoid additional name server 136 attempts. If there is an MX record without an additional A 137 record, delete it (this avoids a problem with misconfigured 138 DNS situations). 139 140X ** Allow a way to extend the $Z macro with local configuration 141 information. 142 143X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 144 145X ** Allow /address in -bt mode to expand address through ruleset 0, 146 aliases, etc. and display results. [8.8] 147 148X ** "R mailer address" in -bt mode does remotename on address. 149 150E ** Adjust "infinite loop in rule" code to handle entire ruleset 151 (Code from Michael Corrigan). 152 153E ** Allow :include: from command line (not SMTP) to assist in 154 "personal list" management -- i.e., creating lists that 155 cannot be EXPNed. 156 157X ** Database (keyed lookup) auto-rebuild. 158 159X ** Find a good test suite and include in the distribution. 160 161S ** You can use symbolic links to point into protected directories. 162 (AEJ) 163 164X ** Extend OI to allow separate settings for canonification, MX, and A 165 lookups. [8.8?] 166 167X ** Add $!x class to match any number of words not in class x. (KRE) 168 169X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 170 171X ** Add "bestmx" map -- returns "best MX host" for this address. 172 Allows you to do automatic detection of when you are the best 173 MX for a given address. [8.7?] 174 175X ** Some way to diddle resolver flags on a per-lookup basis, such 176 as a flag to the map declaration. (Rick McCarty) 177 - Is this really a good idea? DNSRCH can be turned off by 178 putting a dot at the end. AAONLY? 179 180X ** Extend makemap to "gather" values -- i.e., merge entries that 181 have the same keys. [8.8] (BCX) 182 183E ** Allow error messages on individual addresses in the qf file. 184 (BCX) 185 186X ** Multi-character option names. [9.1] 187 188X ** User database extensions for mailing lists: 189 list:precedence -- Precedence: value for new message 190 list:envelopefrom -- envelope "from" value for new message 191 others? [8.8] 192 193X ** Command line switch to set precedence (for mailing list 194 generation). (BCX) 195 196B ** Restore `T' line to eliminate X-Authentication-Warning: at 197 inappropriate times. (Christophe Wolfhugel) 198 - T could become a shorthand for Ct -- i.e., create a new 199 predefined class. 200 - Eliminate "<user> set sender to <address>" message entirely? 201 (this is the workaround) 202 203B ** Return-Path: header should have <> added if not already there. 204 205X ** Add heuristic to determine if other end is a sendmail; use 206 that to decide whether or not to honor F=I mailer flag. 207 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 208 209X ** Automatically drop into MIME mode if you have a full name 210 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 211 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 212 213X ** -b? flag to read a header and show you what it will look like 214 after all rewriting for an indicated address. 215 216E ** Log $u in logsender() (for=<someaddress>). 217 218B ** Include SOCKADDR in MCI struct for logging (currently gives 219 a sockaddr of zero when printing from the cache). 220 221X ** Allow option to set the characters that are autoquoted in 222 addresses? 223 224X * Map that does MB/MR lookups. Rick McCarty <mccarty@io.com>. 225 226X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 227 228X * -V flag to print state of all (?) compilation flags. 229 230X * Handle Expires: header field (if still in queue). 231 232X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 233 (Bruce Lilly <blilly!bruce@uu.psi.com>) 234 235X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 236 237B * EXPN adds @domain to all mailers, including prog. Is this right? 238 [Bob Henry] 239 240B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 241 242E * Change body put code to time out around individual puts. This will 243 make the timeout algorithm more responsive and more resilient. 244 Unfortunately, it's also a pain in the butt. 245 246X * Some way to relay unfound local users to another site. 247 248X * Disable all default RW sets except mailer-specific? 249
