1(Version 8.22 of 03/12/94) 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 **** 8 -> 7 bit MIME conversion. 11 12E **** Change NoReturn to be an envelope flag. [8.7] 13 14X **** Add M_NOLOOPBACKCHK (k) mailer flag to turn off check of name in 15 HELO command. [8.8] 16 17X **** Merge Sun changes. [8.7] 18 19X **** Macro giving size of the message in bytes. 20 21X **** Create a "service switch" abstraction that will interface with 22 Sun NSS, Ultrix /etc/svc.conf, etc. This will allow you to 23 turn off DNS entirely, a la ``OIoff''. [8.7] 24 25X **** Should have new mailer flags to override LocalMailer stuff: 26 - M_ALIASABLE (A) -- can use as the LHS of an alias. 27 - M_HASPWENT (w) -- should have a /etc/passwd entry. If not found 28 there, implies user unknown. Also implies .forward and UDB 29 searching, search for |, /, and :include:, etc.). 30 - Actually, UDB searching and |, /, and :include: mapping should 31 probably be on another flag. (Cannot be 'l' for back compat 32 reasons.) 33 - Need for $@host part of triple and Return-Receipt-To: processing 34 should also be split apart. 35 [8.8] 36 37X **** Mailer flag to enable/disable surrounding route-addrs with 38 angle brackets in setsender(). UUCP cleanup scripts treat 39 these as file redirection. 40 41X **** Mailer flag to override MX lookups. 42 43E **** Fix parseaddr to return a dummy mailer with QBADADDR set for 44 all cases except null input; change calls to be more sceptical 45 about the return value, checking this bit instead of just 46 checking for == NULL. (Eric Wassenaar) [8.7] 47 48X **** Run time configurable locking -- e.g., compile in HASFLOCK and 49 HASLOCKF, and then choose at runtime between these. 50 51B **** Aliases with .REDIRECT fail during newaliases if the "n" flag 52 is given. Problem is, sometimes you want them to, sometimes 53 you don't. Perhaps two flavors of "error" mailer? 54 55B **** Calls to gethostbyname with a trailing dot fail if you are 56 not running DNS. 57 58E **** Move delivery forking from sendenvelope to sendall so that 59 the connection cache works between split envelopes, and to 60 avoid a flurry of processes should you be sending to lots of 61 sub-lists. 62 63X **** Add uucp-bang mailer that strips off any domain name from 64 the envelope recipient address first; this is for use in 65 mailer table entries. 66 67X **** "quote" map (inverse of dequote). Lets you turn node::user 68 into "node::user"@DECNET.gateway 69 70X **** Named rulesets. 71 72? **** Should $( [1.2.3.4] $) convert the address to a name? 73 74E **** Change collect() handling to use high level timeouts instead 75 of per-line timeouts -- the current mechanism is swamping 76 the machine with system calls. (Look at KJS code.) 77 78E *** Long term host status -- store host status on disk for sharing 79 between runs. 80 81X *** Extend I option to allow setting of retry and timeout values. 82 drl@vuse.vanderbilt.edu (David R. Linn). 83 84X *** Total connection cache lifespan timeout -- a way to give a 85 timeout on connections regardless of whether they are active 86 or not. For single threaded servers such as Microsoft SMTP 87 gateway. Douglas Anderson <dlander@afterlife.ncsc.mil>. 88 89X *** Mailer flag that does a "ping" equivalent -- if it fails, wait 90 30 seconds and try again (for dialup PPP connections). Could 91 just try the connection and then immediately retry on some 92 kinds of failures. 93 94X *** Create a macro that has message size. 95 Peter Wemm <peter@DIALix.oz.au> 96 97E *** Dynamically allocate MAXNAME buffers for headers. 98 99E *** Dynamically allocate "line" buffer in readaliases(). 100 101X *** Add ability to disable Return-Receipt-To: on a privacy flag. [8.8] 102 103X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 104 105X *** Runtime option to enable/disable IDENT protocol. 106 107E *** Don't send ErrMsgFile to postmaster bounces. (Josh Smith, 108 josh@osiris.ac.hmc.edu). 109 110X *** Add "user" map to look up a user name via getpwnam -- so that 111 non-local names can be forwarded to another site. [8.8] 112 113E *** Have daemons that start up check the alias database for 114 correctness and auto-rebuild if necessary. This is to handle 115 the case of a system crash during an alias database rebuild. 116 117E *** Eliminate E qf line and e_errorqueue; use e_errorsto a la 118 e_receiptto. This simplifies and gives symmetry. (Eric 119 Wassenaar) 120 121X *** DECNET_RELAY support in configs. 122 123X *** -wN command line flag to set the width of mailq output. 124 (Allan Johannesen) 125 126E *** Move mailertable lookup after UUCP-specific class checks? 127 (Kimmo Suominen <kim@tac.nyc.ny.us>) 128 129E *** Users in more than one list with different owners get duplicate 130 deliveries -- maybe just assign them arbitrarily to one 131 envelope or the other? 132 133X ** Make MAXBADCOMMANDS run time configurable. 134 135E ** Allow mailertable entries of the form ``error:message''. 136 137X ** Have .forward files re-queue if the home directory isn't 138 accessible? On some option... 139 (Q.G.Campbell@newcastle.ac.uk) 140 141X ** Have local delivery queue if NIS is down? On some option... 142 (Q.G.Campbell@newcastle.ac.uk) 143 144E ** Have nullclient configuration resolve local names to the local 145 mailer and then redirect them in ruleset 5; this allows you to 146 redirect root differently depending on the client. It's not 147 clear this is really a good idea though. 148 149E ** Move CurHostAddr into mci struct, and make CurMCI variable 150 point to this, so that logging will give the correct address 151 instead of (0) for cached connections. Motonori Nakamura. 152 153X ** Allow use of a generalized network service for aliasing? 154 How would the protocol be defined? 155 James Gritton <gritton@byu.edu>. 156 157E ** Make "local configuration error" a temporary failure? 158 (add EX_CONFIG to the markfailure list) 159 160X ** (sigh) BSMTP. 161 162X ** "E" configuration line that sets environment variables. 163 164E ** Change listen() high-load backoff to accept and issue a 4xx 165 message so that it responds more quickly. 166 167E ** Change "/usr/tmp/dead.letter" to be based on _PATH_VARTMP. 168 169B ** Commas in NAME envariable cause problems (Peter Wan 170 <peter@cc.gatech.edu>). Merge with suggestions to use 171 MIME-format for 8-bit characters? 172 173E ** Save address information that comes back as the "additional 174 records" part of an MX lookup, to avoid additional name server 175 attempts. If there is an MX record without an additional A 176 record, delete it (this avoids a problem with misconfigured 177 DNS situations). 178 179X ** Allow a way to extend the $Z macro with local configuration 180 information. 181 182X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 183 184X ** Allow /address in -bt mode to expand address through ruleset 0, 185 aliases, etc. and display results. [8.8] 186 187X ** "R mailer address" in -bt mode does remotename on address. 188 189E ** Adjust "infinite loop in rule" code to handle entire ruleset 190 (Code from Michael Corrigan). 191 192E ** Allow :include: from command line (not SMTP) to assist in 193 "personal list" management -- i.e., creating lists that 194 cannot be EXPNed. 195 196X ** Database (keyed lookup) auto-rebuild. 197 198X ** Find a good test suite and include in the distribution. 199 200S ** You can use symbolic links to point into protected directories. 201 (AEJ) 202 203X ** Extend OI to allow separate settings for canonification, MX, and A 204 lookups. [8.8?] 205 206X ** Add $!x class to match any number of words not in class x. (KRE) 207 208X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 209 210X ** Add "bestmx" map -- returns "best MX host" for this address. 211 Allows you to do automatic detection of when you are the best 212 MX for a given address. [8.7?] 213 214X ** Some way to diddle resolver flags on a per-lookup basis, such 215 as a flag to the map declaration. (Rick McCarty) 216 - Is this really a good idea? DNSRCH can be turned off by 217 putting a dot at the end. AAONLY? 218 219X ** Extend makemap to "gather" values -- i.e., merge entries that 220 have the same keys. [8.8] (BCX) 221 222E ** Allow error messages on individual addresses in the qf file. 223 (BCX) 224 225X ** Multi-character option names. [9.1] 226 227X ** User database extensions for mailing lists: 228 list:precedence -- Precedence: value for new message 229 list:envelopefrom -- envelope "from" value for new message 230 others? [8.8] 231 232X ** Command line switch to set precedence (for mailing list 233 generation). (BCX) 234 235B ** Restore `T' line to eliminate X-Authentication-Warning: at 236 inappropriate times. (Christophe Wolfhugel) 237 - T could become a shorthand for Ct -- i.e., create a new 238 predefined class. 239 - Eliminate "<user> set sender to <address>" message entirely? 240 (this is the workaround) 241 242B ** Return-Path: header should have <> added if not already there. 243 244X ** Add heuristic to determine if other end is a sendmail; use 245 that to decide whether or not to honor F=I mailer flag. 246 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 247 248X ** Automatically drop into MIME mode if you have a full name 249 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 250 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 251 252X ** -b? flag to read a header and show you what it will look like 253 after all rewriting for an indicated address. 254 255E ** Log $u in logsender() (for=<someaddress>). 256 257B ** Include SOCKADDR in MCI struct for logging (currently gives 258 a sockaddr of zero when printing from the cache). 259 260X ** Allow option to set the characters that are autoquoted in 261 addresses? 262 263X * Map that does MB/MR lookups. Rick McCarty <mccarty@io.com>. 264 265X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 266 267X * -V flag to print state of all (?) compilation flags. 268 269X * Handle Expires: header field (if still in queue). 270 271X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 272 (Bruce Lilly <blilly!bruce@uu.psi.com>) 273 274X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 275 276B * EXPN adds @domain to all mailers, including prog. Is this right? 277 [Bob Henry] 278 279B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 280 281E * Change body put code to time out around individual puts. This will 282 make the timeout algorithm more responsive and more resilient. 283 Unfortunately, it's also a pain in the butt. 284 285X * Some way to relay unfound local users to another site. 286 287X * Disable all default RW sets except mailer-specific? 288
