1(Version 8.27 of 11/13/94) 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 **** Merge Sun changes. [8.7] 11 12E **** Fix parseaddr to return a dummy mailer with QBADADDR set for 13 all cases except null input; change calls to be more sceptical 14 about the return value, checking this bit instead of just 15 checking for == NULL. (Eric Wassenaar) [8.7] 16 17X **** Run time configurable locking -- e.g., compile in HASFLOCK and 18 HASLOCKF, and then choose at runtime between these. 19 20B **** Aliases with .REDIRECT fail during newaliases if the "n" flag 21 is given. Problem is, sometimes you want them to, sometimes 22 you don't. Perhaps two flavors of "error" mailer? 23 24B **** Calls to gethostbyname with a trailing dot fail if you are 25 not running DNS. 26 27X **** Add uucp-bang mailer that strips off any domain name from 28 the envelope recipient address first; this is for use in 29 mailer table entries. 30 31X **** "quote" map (inverse of dequote). Lets you turn node::user 32 into "node::user"@DECNET.gateway 33 34X **** Named rulesets. 35 36? **** Should $( [1.2.3.4] $) convert the address to a name? 37 38E *** Arrange to run queue jobs as the owner of that queue file. This 39 probably requires forcing a fork in order to be able to completely 40 restore the uid/gid portably without leaking out root privileges. 41 42E *** Long term host status -- store host status on disk for sharing 43 between runs. 44 45X *** Extend I option to allow setting of retry and timeout values. 46 drl@vuse.vanderbilt.edu (David R. Linn). 47 48X *** Total connection cache lifespan timeout -- a way to give a 49 timeout on connections regardless of whether they are active 50 or not. For single threaded servers such as Microsoft SMTP 51 gateway. Douglas Anderson <dlander@afterlife.ncsc.mil>. 52 53X *** Mailer flag that does a "ping" equivalent -- if it fails, wait 54 30 seconds and try again (for dialup PPP connections). Could 55 just try the connection and then immediately retry on some 56 kinds of failures. 57 58X *** Create a macro that has message size. 59 Peter Wemm <peter@DIALix.oz.au> 60 61E *** Dynamically allocate MAXNAME buffers for headers. 62 63E *** Dynamically allocate "line" buffer in readaliases(). 64 65X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 66 67E *** Don't send ErrMsgFile to postmaster bounces. (Josh Smith, 68 josh@osiris.ac.hmc.edu). 69 70E *** Have daemons that start up check the alias database for 71 correctness and auto-rebuild if necessary. This is to handle 72 the case of a system crash during an alias database rebuild. 73 74E *** Eliminate E qf line and e_errorqueue; use e_errorsto a la 75 e_receiptto. This simplifies and gives symmetry. (Eric 76 Wassenaar) 77 78X *** DECNET_RELAY support in configs. 79 80X *** -wN command line flag to set the width of mailq output. 81 (Allan Johannesen) 82 83E *** Move mailertable lookup after UUCP-specific class checks? 84 (Kimmo Suominen <kim@tac.nyc.ny.us>) 85 86E *** Users in more than one list with different owners get duplicate 87 deliveries -- maybe just assign them arbitrarily to one 88 envelope or the other? 89 90X ** Make MAXBADCOMMANDS run time configurable. 91 92E ** Allow mailertable entries of the form ``error:message''. 93 94X ** Have .forward files re-queue if the home directory isn't 95 accessible? On some option... 96 (Q.G.Campbell@newcastle.ac.uk) 97 98X ** Have local delivery queue if NIS is down? On some option... 99 (Q.G.Campbell@newcastle.ac.uk) 100 101E ** Have nullclient configuration resolve local names to the local 102 mailer and then redirect them in ruleset 5; this allows you to 103 redirect root differently depending on the client. It's not 104 clear this is really a good idea though. 105 106E ** Move CurHostAddr into mci struct, and make CurMCI variable 107 point to this, so that logging will give the correct address 108 instead of (0) for cached connections. Motonori Nakamura. 109 110X ** Allow use of a generalized network service for aliasing? 111 How would the protocol be defined? 112 James Gritton <gritton@byu.edu>. 113 114E ** Make "local configuration error" a temporary failure? 115 (add EX_CONFIG to the markfailure list) 116 117X ** (sigh) BSMTP. 118 119X ** "E" configuration line that sets environment variables. 120 121E ** Change listen() high-load backoff to accept and issue a 4xx 122 message so that it responds more quickly. 123 124E ** Change "/usr/tmp/dead.letter" to be based on _PATH_VARTMP. 125 126B ** Commas in NAME envariable cause problems (Peter Wan 127 <peter@cc.gatech.edu>). Merge with suggestions to use 128 MIME-format for 8-bit characters? 129 130E ** Save address information that comes back as the "additional 131 records" part of an MX lookup, to avoid additional name server 132 attempts. If there is an MX record without an additional A 133 record, delete it (this avoids a problem with misconfigured 134 DNS situations). 135 136X ** Allow a way to extend the $Z macro with local configuration 137 information. 138 139X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 140 141X ** Allow /address in -bt mode to expand address through ruleset 0, 142 aliases, etc. and display results. [8.8] 143 144X ** "R mailer address" in -bt mode does remotename on address. 145 146E ** Adjust "infinite loop in rule" code to handle entire ruleset 147 (Code from Michael Corrigan). 148 149E ** Allow :include: from command line (not SMTP) to assist in 150 "personal list" management -- i.e., creating lists that 151 cannot be EXPNed. 152 153X ** Database (keyed lookup) auto-rebuild. 154 155X ** Find a good test suite and include in the distribution. 156 157S ** You can use symbolic links to point into protected directories. 158 (AEJ) 159 160X ** Extend OI to allow separate settings for canonification, MX, and A 161 lookups. [8.8?] 162 163X ** Add $!x class to match any number of words not in class x. (KRE) 164 165X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 166 167X ** Add "bestmx" map -- returns "best MX host" for this address. 168 Allows you to do automatic detection of when you are the best 169 MX for a given address. [8.7?] 170 171X ** Some way to diddle resolver flags on a per-lookup basis, such 172 as a flag to the map declaration. (Rick McCarty) 173 - Is this really a good idea? DNSRCH can be turned off by 174 putting a dot at the end. AAONLY? 175 176X ** Extend makemap to "gather" values -- i.e., merge entries that 177 have the same keys. [8.8] (BCX) 178 179E ** Allow error messages on individual addresses in the qf file. 180 (BCX) 181 182X ** Multi-character option names. [9.1] 183 184X ** User database extensions for mailing lists: 185 list:precedence -- Precedence: value for new message 186 list:envelopefrom -- envelope "from" value for new message 187 others? [8.8] 188 189X ** Command line switch to set precedence (for mailing list 190 generation). (BCX) 191 192B ** Restore `T' line to eliminate X-Authentication-Warning: at 193 inappropriate times. (Christophe Wolfhugel) 194 - T could become a shorthand for Ct -- i.e., create a new 195 predefined class. 196 - Eliminate "<user> set sender to <address>" message entirely? 197 (this is the workaround) 198 199B ** Return-Path: header should have <> added if not already there. 200 201X ** Add heuristic to determine if other end is a sendmail; use 202 that to decide whether or not to honor F=I mailer flag. 203 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 204 205X ** Automatically drop into MIME mode if you have a full name 206 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 207 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 208 209X ** -b? flag to read a header and show you what it will look like 210 after all rewriting for an indicated address. 211 212E ** Log $u in logsender() (for=<someaddress>). 213 214B ** Include SOCKADDR in MCI struct for logging (currently gives 215 a sockaddr of zero when printing from the cache). 216 217X ** Allow option to set the characters that are autoquoted in 218 addresses? 219 220X * Map that does MB/MR lookups. Rick McCarty <mccarty@io.com>. 221 222X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 223 224X * -V flag to print state of all (?) compilation flags. 225 226X * Handle Expires: header field (if still in queue). 227 228X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 229 (Bruce Lilly <blilly!bruce@uu.psi.com>) 230 231X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 232 233B * EXPN adds @domain to all mailers, including prog. Is this right? 234 [Bob Henry] 235 236B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 237 238E * Change body put code to time out around individual puts. This will 239 make the timeout algorithm more responsive and more resilient. 240 Unfortunately, it's also a pain in the butt. 241 242X * Some way to relay unfound local users to another site. 243 244X * Disable all default RW sets except mailer-specific? 245
