1(Version 8.36 of 04/09/95) 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 36E **** Change userdb code to use underlying maps, at least for 37 :mailname; this lets people use NIS to supply generics 38 information. (Or should the generics code just be broken 39 out into the config file?) 40 41? **** Should $( [1.2.3.4] $) convert the address to a name? 42 43E *** Have recipient lines rewritten by the user database. 44 45E *** Arrange to run queue jobs as the owner of that queue file. This 46 probably requires forcing a fork in order to be able to completely 47 restore the uid/gid portably without leaking out root privileges. 48 49E *** Long term host status -- store host status on disk for sharing 50 between runs. 51 52X *** Extend I option to allow setting of retry and timeout values. 53 drl@vuse.vanderbilt.edu (David R. Linn). 54 55X *** Total connection cache lifespan timeout -- a way to give a 56 timeout on connections regardless of whether they are active 57 or not. For single threaded servers such as Microsoft SMTP 58 gateway. Douglas Anderson <dlander@afterlife.ncsc.mil>. 59 60X *** Create a macro that has message size. 61 Peter Wemm <peter@DIALix.oz.au> 62 63E *** Dynamically allocate MAXNAME buffers for headers. 64 65E *** Dynamically allocate "line" buffer in readaliases(). 66 67X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 68 69E *** Don't send ErrMsgFile to postmaster bounces. (Josh Smith, 70 josh@osiris.ac.hmc.edu). 71 72E *** Have daemons that start up check the alias database for 73 correctness and auto-rebuild if necessary. This is to handle 74 the case of a system crash during an alias database rebuild. 75 76E *** Eliminate E qf line and e_errorqueue; use e_errorsto a la 77 e_receiptto. This simplifies and gives symmetry. (Eric 78 Wassenaar) 79 80X *** DECNET_RELAY support in configs. 81 82X *** -wN command line flag to set the width of mailq output. 83 (Allan Johannesen) 84 85E *** Move mailertable lookup after UUCP-specific class checks? 86 (Kimmo Suominen <kim@tac.nyc.ny.us>) 87 88E *** Users in more than one list with different owners get duplicate 89 deliveries -- maybe just assign them arbitrarily to one 90 envelope or the other? 91 92E *** Mailer flag to turn off MX lookups. 93 94X ** Rewriting rules based on incoming mailer. 95 96X ** Have a ruleset (6?) that gets both sender and recipient 97 addresses to check compatibility. Can you do enough interesting 98 things with this? 99 100X ** Make MAXBADCOMMANDS run time configurable. 101 102E ** Allow mailertable entries of the form ``error:message''. 103 104X ** Have .forward files re-queue if the home directory isn't 105 accessible? On some option... 106 (Q.G.Campbell@newcastle.ac.uk) 107 108X ** Have local delivery queue if NIS is down? On some option... 109 (Q.G.Campbell@newcastle.ac.uk) 110 111E ** Have nullclient configuration resolve local names to the local 112 mailer and then redirect them in ruleset 5; this allows you to 113 redirect root differently depending on the client. It's not 114 clear this is really a good idea though. 115 116E ** Move CurHostAddr into mci struct, and make CurMCI variable 117 point to this, so that logging will give the correct address 118 instead of (0) for cached connections. Motonori Nakamura. 119 120X ** Allow use of a generalized network service for aliasing? 121 How would the protocol be defined? 122 James Gritton <gritton@byu.edu>. 123 124E ** Make "local configuration error" a temporary failure? 125 (add EX_CONFIG to the markfailure list) 126 127X ** (sigh) BSMTP. 128 129X ** "E" configuration line that sets environment variables. 130 131E ** Change listen() high-load backoff to accept and issue a 4xx 132 message so that it responds more quickly. 133 134B ** Commas in NAME envariable cause problems (Peter Wan 135 <peter@cc.gatech.edu>). Merge with suggestions to use 136 MIME-format for 8-bit characters? 137 138E ** Save address information that comes back as the "additional 139 records" part of an MX lookup, to avoid additional name server 140 attempts. If there is an MX record without an additional A 141 record, delete it (this avoids a problem with misconfigured 142 DNS situations). 143 144X ** Allow a way to extend the $Z macro with local configuration 145 information. 146 147X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 148 149X ** Allow /address in -bt mode to expand address through ruleset 0, 150 aliases, etc. and display results. [8.8] 151 152X ** "R mailer address" in -bt mode does remotename on address. 153 154E ** Adjust "infinite loop in rule" code to handle entire ruleset 155 (Code from Michael Corrigan). 156 157E ** Allow :include: from command line (not SMTP) to assist in 158 "personal list" management -- i.e., creating lists that 159 cannot be EXPNed. 160 161X ** Database (keyed lookup) auto-rebuild. 162 163X ** Find a good test suite and include in the distribution. 164 165S ** You can use symbolic links to point into protected directories. 166 (AEJ) 167 168X ** Extend OI to allow separate settings for canonification, MX, and A 169 lookups. [8.8?] 170 171X ** Add $!x class to match any number of words not in class x. (KRE) 172 173X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 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 ** User database extensions for mailing lists: 187 list:precedence -- Precedence: value for new message 188 list:envelopefrom -- envelope "from" value for new message 189 others? [8.8] 190 191X ** Command line switch to set precedence (for mailing list 192 generation). (BCX) 193 194B ** Return-Path: header should have <> added if not already there. 195 196X ** Add heuristic to determine if other end is a sendmail; use 197 that to decide whether or not to honor F=I mailer flag. 198 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 199 200X ** Automatically drop into MIME mode if you have a full name 201 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 202 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 203 204X ** -b? flag to read a header and show you what it will look like 205 after all rewriting for an indicated address. 206 207E ** Log $u in logsender() (for=<someaddress>). 208 209B ** Include SOCKADDR in MCI struct for logging (currently gives 210 a sockaddr of zero when printing from the cache). 211 212X ** Allow option to set the characters that are autoquoted in 213 addresses? 214 215X * Map that does MB/MR lookups. Rick McCarty <mccarty@io.com>. 216 217X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 218 219X * -V flag to print state of all (?) compilation flags. 220 221X * Handle Expires: header field (if still in queue). 222 223X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 224 (Bruce Lilly <blilly!bruce@uu.psi.com>) 225 226X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 227 228B * EXPN adds @domain to all mailers, including prog. Is this right? 229 [Bob Henry] 230 231B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 232 233E * Change body put code to time out around individual puts. This will 234 make the timeout algorithm more responsive and more resilient. 235 Unfortunately, it's also a pain in the butt. 236 237X * Some way to relay unfound local users to another site. 238 239X * Disable all default RW sets except mailer-specific? 240 241 242------------------------------------------------------------------------------- 243 244IDA Features that have been requested: 245 246* USERMAILER 247 248* LOCAL_MX_HANDLER 249 250* NIS_MAILHOST 251 252* GENERICFROM 253
