1(Version 8.26 of 08/08/94) 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 12X **** Create a "service switch" abstraction that will interface with 13 Sun NSS, Ultrix /etc/svc.conf, etc. This will allow you to 14 turn off DNS entirely, a la ``OIoff''. [8.7] 15 16E **** Fix parseaddr to return a dummy mailer with QBADADDR set for 17 all cases except null input; change calls to be more sceptical 18 about the return value, checking this bit instead of just 19 checking for == NULL. (Eric Wassenaar) [8.7] 20 21X **** Run time configurable locking -- e.g., compile in HASFLOCK and 22 HASLOCKF, and then choose at runtime between these. 23 24B **** Aliases with .REDIRECT fail during newaliases if the "n" flag 25 is given. Problem is, sometimes you want them to, sometimes 26 you don't. Perhaps two flavors of "error" mailer? 27 28B **** Calls to gethostbyname with a trailing dot fail if you are 29 not running DNS. 30 31E **** Move delivery forking from sendenvelope to sendall so that 32 the connection cache works between split envelopes, and to 33 avoid a flurry of processes should you be sending to lots of 34 sub-lists. 35 36X **** Add uucp-bang mailer that strips off any domain name from 37 the envelope recipient address first; this is for use in 38 mailer table entries. 39 40X **** "quote" map (inverse of dequote). Lets you turn node::user 41 into "node::user"@DECNET.gateway 42 43X **** Named rulesets. 44 45? **** Should $( [1.2.3.4] $) convert the address to a name? 46 47X **** Add smrsh to release. 48 49E *** Arrange to run queue jobs as the owner of that queue file. This 50 probably requires forcing a fork in order to be able to completely 51 restore the uid/gid portably without leaking out root privileges. 52 53E *** Long term host status -- store host status on disk for sharing 54 between runs. 55 56X *** Extend I option to allow setting of retry and timeout values. 57 drl@vuse.vanderbilt.edu (David R. Linn). 58 59X *** Total connection cache lifespan timeout -- a way to give a 60 timeout on connections regardless of whether they are active 61 or not. For single threaded servers such as Microsoft SMTP 62 gateway. Douglas Anderson <dlander@afterlife.ncsc.mil>. 63 64X *** Mailer flag that does a "ping" equivalent -- if it fails, wait 65 30 seconds and try again (for dialup PPP connections). Could 66 just try the connection and then immediately retry on some 67 kinds of failures. 68 69X *** Create a macro that has message size. 70 Peter Wemm <peter@DIALix.oz.au> 71 72E *** Dynamically allocate MAXNAME buffers for headers. 73 74E *** Dynamically allocate "line" buffer in readaliases(). 75 76X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 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 92X *** DECNET_RELAY support in configs. 93 94X *** -wN command line flag to set the width of mailq output. 95 (Allan Johannesen) 96 97E *** Move mailertable lookup after UUCP-specific class checks? 98 (Kimmo Suominen <kim@tac.nyc.ny.us>) 99 100E *** Users in more than one list with different owners get duplicate 101 deliveries -- maybe just assign them arbitrarily to one 102 envelope or the other? 103 104X ** Make MAXBADCOMMANDS run time configurable. 105 106E ** Allow mailertable entries of the form ``error:message''. 107 108X ** Have .forward files re-queue if the home directory isn't 109 accessible? On some option... 110 (Q.G.Campbell@newcastle.ac.uk) 111 112X ** Have local delivery queue if NIS is down? On some option... 113 (Q.G.Campbell@newcastle.ac.uk) 114 115E ** Have nullclient configuration resolve local names to the local 116 mailer and then redirect them in ruleset 5; this allows you to 117 redirect root differently depending on the client. It's not 118 clear this is really a good idea though. 119 120E ** Move CurHostAddr into mci struct, and make CurMCI variable 121 point to this, so that logging will give the correct address 122 instead of (0) for cached connections. Motonori Nakamura. 123 124X ** Allow use of a generalized network service for aliasing? 125 How would the protocol be defined? 126 James Gritton <gritton@byu.edu>. 127 128E ** Make "local configuration error" a temporary failure? 129 (add EX_CONFIG to the markfailure list) 130 131X ** (sigh) BSMTP. 132 133X ** "E" configuration line that sets environment variables. 134 135E ** Change listen() high-load backoff to accept and issue a 4xx 136 message so that it responds more quickly. 137 138E ** Change "/usr/tmp/dead.letter" to be based on _PATH_VARTMP. 139 140B ** Commas in NAME envariable cause problems (Peter Wan 141 <peter@cc.gatech.edu>). Merge with suggestions to use 142 MIME-format for 8-bit characters? 143 144E ** Save address information that comes back as the "additional 145 records" part of an MX lookup, to avoid additional name server 146 attempts. If there is an MX record without an additional A 147 record, delete it (this avoids a problem with misconfigured 148 DNS situations). 149 150X ** Allow a way to extend the $Z macro with local configuration 151 information. 152 153X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 154 155X ** Allow /address in -bt mode to expand address through ruleset 0, 156 aliases, etc. and display results. [8.8] 157 158X ** "R mailer address" in -bt mode does remotename on address. 159 160E ** Adjust "infinite loop in rule" code to handle entire ruleset 161 (Code from Michael Corrigan). 162 163E ** Allow :include: from command line (not SMTP) to assist in 164 "personal list" management -- i.e., creating lists that 165 cannot be EXPNed. 166 167X ** Database (keyed lookup) auto-rebuild. 168 169X ** Find a good test suite and include in the distribution. 170 171S ** You can use symbolic links to point into protected directories. 172 (AEJ) 173 174X ** Extend OI to allow separate settings for canonification, MX, and A 175 lookups. [8.8?] 176 177X ** Add $!x class to match any number of words not in class x. (KRE) 178 179X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 180 181X ** Add "bestmx" map -- returns "best MX host" for this address. 182 Allows you to do automatic detection of when you are the best 183 MX for a given address. [8.7?] 184 185X ** Some way to diddle resolver flags on a per-lookup basis, such 186 as a flag to the map declaration. (Rick McCarty) 187 - Is this really a good idea? DNSRCH can be turned off by 188 putting a dot at the end. AAONLY? 189 190X ** Extend makemap to "gather" values -- i.e., merge entries that 191 have the same keys. [8.8] (BCX) 192 193E ** Allow error messages on individual addresses in the qf file. 194 (BCX) 195 196X ** Multi-character option names. [9.1] 197 198X ** User database extensions for mailing lists: 199 list:precedence -- Precedence: value for new message 200 list:envelopefrom -- envelope "from" value for new message 201 others? [8.8] 202 203X ** Command line switch to set precedence (for mailing list 204 generation). (BCX) 205 206B ** Restore `T' line to eliminate X-Authentication-Warning: at 207 inappropriate times. (Christophe Wolfhugel) 208 - T could become a shorthand for Ct -- i.e., create a new 209 predefined class. 210 - Eliminate "<user> set sender to <address>" message entirely? 211 (this is the workaround) 212 213B ** Return-Path: header should have <> added if not already there. 214 215X ** Add heuristic to determine if other end is a sendmail; use 216 that to decide whether or not to honor F=I mailer flag. 217 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 218 219X ** Automatically drop into MIME mode if you have a full name 220 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 221 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 222 223X ** -b? flag to read a header and show you what it will look like 224 after all rewriting for an indicated address. 225 226E ** Log $u in logsender() (for=<someaddress>). 227 228B ** Include SOCKADDR in MCI struct for logging (currently gives 229 a sockaddr of zero when printing from the cache). 230 231X ** Allow option to set the characters that are autoquoted in 232 addresses? 233 234X * Map that does MB/MR lookups. Rick McCarty <mccarty@io.com>. 235 236X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 237 238X * -V flag to print state of all (?) compilation flags. 239 240X * Handle Expires: header field (if still in queue). 241 242X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 243 (Bruce Lilly <blilly!bruce@uu.psi.com>) 244 245X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 246 247B * EXPN adds @domain to all mailers, including prog. Is this right? 248 [Bob Henry] 249 250B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 251 252E * Change body put code to time out around individual puts. This will 253 make the timeout algorithm more responsive and more resilient. 254 Unfortunately, it's also a pain in the butt. 255 256X * Some way to relay unfound local users to another site. 257 258X * Disable all default RW sets except mailer-specific? 259
