1(Version 8.20 of 02/06/94) 2 3Key: 4 X -- extension (user visible change) 5 B -- bug fix 6 S -- security fix 7 E -- enhancement to existing algorithm 8 9B **** CNAME loops cause message to be both queued and bounced. 10 "Right" fix is to change dropenvelope et al to do one or 11 the other, but could this cause other problems? 12 Eric Hagberg <hagberg@med.cornell.edu> 13 14X **** 8 -> 7 bit MIME conversion. 15 16E **** Change NoReturn to be an envelope flag. [8.7] 17 18X **** Add M_NOLOOPBACKCHK (k) mailer flag to turn off check of name in 19 HELO command. [8.8] 20 21X **** Merge Sun changes. [8.7] 22 23X **** Macro giving size of the message in bytes. 24 25X **** Create a "service switch" abstraction that will interface with 26 Sun NSS, Ultrix /etc/svc.conf, etc. This will allow you to 27 turn off DNS entirely, a la ``OIoff''. [8.7] 28 29X **** Should have new mailer flags to override LocalMailer stuff: 30 - M_ALIASABLE (A) -- can use as the LHS of an alias. 31 - M_HASPWENT (w) -- should have a /etc/passwd entry. If not found 32 there, implies user unknown. Also implies .forward and UDB 33 searching, search for |, /, and :include:, etc.). 34 - Actually, UDB searching and |, /, and :include: mapping should 35 probably be on another flag. (Cannot be 'l' for back compat 36 reasons.) 37 - Need for $@host part of triple and Return-Receipt-To: processing 38 should also be split apart. 39 [8.8] 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 74X **** Let I option include retry count etc. 75 drl@vuse.vanderbilt.edu (David R. Linn) 76 77X *** Extend I option to allow setting of retry and timeout values. 78 drl@vuse.vanderbilt.edu (David R. Linn). 79 80X *** Total connection cache lifespan timeout -- a way to give a 81 timeout on connections regardless of whether they are active 82 or not. For single threaded servers such as Microsoft SMTP 83 gateway. Douglas Anderson <dlander@afterlife.ncsc.mil>. 84 85X *** Mailer flag that does a "ping" equivalent -- if it fails, wait 86 30 seconds and try again (for dialup PPP connections). Could 87 just try the connection and then immediately retry on some 88 kinds of failures. 89 90X *** Create a macro that has message size. 91 Peter Wemm <peter@DIALix.oz.au> 92 93E *** Dynamically allocate MAXNAME buffers for headers. 94 95E *** Dynamically allocate "line" buffer in readaliases(). 96 97X *** Add ability to disable Return-Receipt-To: on a privacy flag. [8.8] 98 99X *** Add -P to set precedence (e.g., -Pbulk). [8.8] (BCX) 100 101X *** Runtime option to enable/disable IDENT protocol. 102 103E *** Don't send ErrMsgFile to postmaster bounces. (Josh Smith, 104 josh@osiris.ac.hmc.edu). 105 106X *** Add "user" map to look up a user name via getpwnam -- so that 107 non-local names can be forwarded to another site. [8.8] 108 109E *** Have daemons that start up check the alias database for 110 correctness and auto-rebuild if necessary. This is to handle 111 the case of a system crash during an alias database rebuild. 112 113E *** Eliminate E qf line and e_errorqueue; use e_errorsto a la 114 e_receiptto. This simplifies and gives symmetry. (Eric 115 Wassenaar) 116 117B *** Fix syslog buffer overflow problems. 118 119X *** DECNET_RELAY support in configs. 120 121X *** -wN command line flag to set the width of mailq output. 122 (Allan Johannesen) 123 124E ** Move CurHostAddr into mci struct, and make CurMCI variable 125 point to this, so that logging will give the correct address 126 instead of (0) for cached connections. Motonori Nakamura. 127 128X ** Allow use of a generalized network service for aliasing? 129 How would the protocol be defined? 130 James Gritton <gritton@byu.edu>. 131 132E ** Make "local configuration error" a temporary failure? 133 (add EX_CONFIG to the markfailure list) 134 135X ** (sigh) BSMTP. 136 137X ** "E" configuration line that sets environment variables. 138 139E ** Change listen() high-load backoff to accept and issue a 4xx 140 message so that it responds more quickly. 141 142E ** Change "/usr/tmp/dead.letter" to be based on _PATH_VARTMP. 143 144B ** Commas in NAME envariable cause problems (Peter Wan 145 <peter@cc.gatech.edu>). Merge with suggestions to use 146 MIME-format for 8-bit characters? 147 148E ** Save address information that comes back as the "additional 149 records" part of an MX lookup, to avoid additional name server 150 attempts. If there is an MX record without an additional A 151 record, delete it (this avoids a problem with misconfigured 152 DNS situations). 153 154X ** Allow a way to extend the $Z macro with local configuration 155 information. 156 157X ** Allow $x in -bt mode to expand macro "x". (BCX) [8.8] 158 159X ** Allow /address in -bt mode to expand address through ruleset 0, 160 aliases, etc. and display results. [8.8] 161 162X ** "R mailer address" in -bt mode does remotename on address. 163 164E ** Adjust "infinite loop in rule" code to handle entire ruleset 165 (Code from Michael Corrigan). 166 167E ** Allow :include: from command line (not SMTP) to assist in 168 "personal list" management -- i.e., creating lists that 169 cannot be EXPNed. 170 171X ** Database (keyed lookup) auto-rebuild. 172 173X ** Find a good test suite and include in the distribution. 174 175S ** You can use symbolic links to point into protected directories. 176 (AEJ) 177 178X ** Extend OI to allow separate settings for canonification, MX, and A 179 lookups. [8.8?] 180 181X ** Add $!x class to match any number of words not in class x. (KRE) 182 183X ** LOCAL_RULE_5 (Spencer Sun, spencer@phoenix.Princeton.EDU) 184 185X ** Add "bestmx" map -- returns "best MX host" for this address. 186 Allows you to do automatic detection of when you are the best 187 MX for a given address. [8.7?] 188 189X ** Some way to diddle resolver flags on a per-lookup basis, such 190 as a flag to the map declaration. (Rick McCarty) 191 - Is this really a good idea? DNSRCH can be turned off by 192 putting a dot at the end. AAONLY? 193 194X ** Extend makemap to "gather" values -- i.e., merge entries that 195 have the same keys. [8.8] (BCX) 196 197E ** Allow error messages on individual addresses in the qf file. 198 (BCX) 199 200X ** Multi-character option names. [9.1] 201 202X ** User database extensions for mailing lists: 203 list:precedence -- Precedence: value for new message 204 list:envelopefrom -- envelope "from" value for new message 205 others? [8.8] 206 207X ** Command line switch to set precedence (for mailing list 208 generation). (BCX) 209 210B ** Restore `T' line to eliminate X-Authentication-Warning: at 211 inappropriate times. (Christophe Wolfhugel) 212 - T could become a shorthand for Ct -- i.e., create a new 213 predefined class. 214 - Eliminate "<user> set sender to <address>" message entirely? 215 (this is the workaround) 216 217B ** Return-Path: header should have <> added if not already there. 218 219X ** Add heuristic to determine if other end is a sendmail; use 220 that to decide whether or not to honor F=I mailer flag. 221 [der Mouse <mouse@collatz.mcrcim.mcgill.edu>] 222 223X ** Automatically drop into MIME mode if you have a full name 224 with 8-bit characters. See envelope.c 8.19.1.1 and util.c 225 8.17.1.1. From Anders Ellefsrud <anders@ifi.uio.no>. 226 227X ** -b? flag to read a header and show you what it will look like 228 after all rewriting for an indicated address. 229 230E ** Log $u in logsender() (for=<someaddress>). 231 232B ** Include SOCKADDR in MCI struct for logging (currently gives 233 a sockaddr of zero when printing from the cache). 234 235X * Map that does MB/MR lookups. Rick McCarty <mccarty@io.com>. 236 237X * Allow $> anywhere in RHS. John Boeske <jboeske@ualberta.ca>. 238 239X * -V flag to print state of all (?) compilation flags. 240 241X * Handle Expires: header field (if still in queue). 242 243X * WIN/3B support (non-atomic rename, no h_addr_list, others?) 244 (Bruce Lilly <blilly!bruce@uu.psi.com>) 245 246X * Sun YBTS daemon uses -ba. [Martin Kiff <MGK@newton.npl.co.uk>] 247 248B * EXPN adds @domain to all mailers, including prog. Is this right? 249 [Bob Henry] 250 251B * EXPN adds @localhost instead of @$M. [Pel Emanuelsson] 252 253E * Change body put code to time out around individual puts. This will 254 make the timeout algorithm more responsive and more resilient. 255 Unfortunately, it's also a pain in the butt. 256 257X * Some way to relay unfound local users to another site. 258 259X * Disable all default RW sets except mailer-specific? 260
