masqmail
view ChangeLog @ 90:d3e39ba684a3
added some words about exim to docs/uucp-setup
exim's rmail handling is similar to the one masqmail had
now masqmail's rmail approach is similar to postfix's
but it still can be called as `rmail' and behaves like exim
in that case then

2 technical view.
4 The code repository log file provides the changes in full detail.

353 or Cc: header,an empty Bcc: header will be created (RFC 822
354 compliance!)
355 * fixed bug: if rcpts are given on command line To: headers were
356 created, even if they already existed. This caused Bcc: recipient
357 addresses to be revealed if they were given on the cmd line.
358 Now a To: header is only created if there is no To:, Cc: or Bcc:
359 header. Thanks to Richard Clamp for pointing this out.

373 * Gregor Hoffleit sent another patch: use liblockfile if available
374 (Debian!) and DESTDIR will be used. Also updated the NEWS file. Thanks
375 again!
376 * define fdatasync to fsync if not available.
377 * lookup.c includes sys/types.h, some environments need this
378 * fixed bug in RFC 822 parsing: name in brackets after address
379 caused problems. Thanks to David Maslen.
380 * values in tables without leading spaces
381 0.0.9:
382 * anyone in group 'trusted' is now allowed to do queue runs. Thanks to
383 Alberto Gonzalez Palomo for the suggestion.
384 * changed umask for spool writing to 026.
385 * removed silly 'no rcpt domain for this route' message
386 * there is now a mailing list
387 (see http://www.innominate.org/mailman/listinfo/masqmail)
388 * Gregor Hoffleit sent a patch to make masqmail work with mutt (and
389 balsa and any other MUA that uses the mutt libs): it now supports
390 '--' in options. Thanks!
391 * accept_message() supports flag ACC_NO_RECVD_HDR (but this is not
392 used in masqmail).
393 * accept_message() is no longer responsible for queuing, makes it
394 easier to recycle the code for other projects (eg. jpilot-Mail)
395 0.0.8:
396 * added a FAQ page.
397 * removed all warnings, at least for egcs. Output of make looks
398 pretty now ;-)
399 * added allowed_mail_locals and not_allowed_mail_locals options for
400 routes.
401 * implemented folding und unfolding of headers (but currently used
402 for the Received: header only).
403 * corrected docs: should be 'online_detect', NOT 'detect_online'.
404 * mailq now gives information about the time mails spent in the queue,
405 the message size and the received host.
406 * added allowed_rcpt_domains option for routes.
407 * increased buffer size to 1024 for SMTP responses when delivering.
408 * fixed minor bug: slash in unquoted strings in conf parsing was not
409 allowed.
410 0.0.7:
411 * fixed a bug in smtp_out.c: sock was tested before it was initialized.
412 * fixed a bug in the configuration code: for statements in two
413 adjacent lines, the second was not recognized.
414 0.0.6:
415 * rewrote part of the configuration parsing code because it caused
416 problems with reading config statements on multiple lines.
417 * added a LF after each mail local mail spool file, as this
418 seems to be required for some MUAs and especially cucipop when
419 it reads mails. Otherwise mails seem to be concatenated. Thanks
420 to Dale Perkel for pointing this out.
421 0.0.5:
422 * added expand_h_sender_domain option (boolean, default: true)
423 because some clients use the Sender: address as the sender address
424 (though it should be the From: address).
425 * changed configure script to better recognize whether libresolv
426 should be linked or not.
427 * fixed a nasty bug: if masqmail -q was called (or qo <name>
428 and a mail was not delivered), the headers were lost! Problem was an
429 additional LF after received_host in the spool file.
430 0.0.4:
431 * 'From' hack is now a 'From ' hack.
432 * configure now accepts options --with-logdir=LOGDIR and
433 --with-spooldir=SPOOLDIR.
434 * the directories /var/masqmail and /var/spool/masqmail will now be
435 created with make install; user and group will be set appropriately
436 * configure now accepts options --with-user=USER and --with-group=GROUP
437 * dove into autoconf: configure now recognizes libc5 and links with
438 libresolv only for libc6 and defines getline for libc5
439 * fixed timeout code when sending. This was broken in some earlier
440 version.
441 0.0.3:
442 * fixed bug in spool write code: rcpt address was written incorrectly
443 to spool file under some circumstances (with a LF).
444 * added methods for online detection (file and mserver) and added code
445 to deliver immediately when mail is received at online time.
446 * too many changes to list: rearranged routing code, unified smtp
447 deliveries to the local net with online deliveries, so now route
448 configurations can be used for the local net. Also multiple messages
449 per connection for the local net possible. And reduced code size.
450 * fixed bug: if server does not use neither the esmtp size extension
451 nor pipelining, output after MAIL FROM was not flushed. So MM waited
452 forever for a response...
453 0.0.2:
454 * fixed bug: euid was not set properly for local delivery
455 * when debugging, it does not write the whole message to the log
456 any more.
457 * added 'From' hack
458 * qualified address for return path and recipients is now required
459 if not accepted locally, if locally accepted the addresses will be
460 qualified with host_name. (Thereby fixed a seg fault bug)
461 * added -i option (same as -oi)
462 * added more header rewriting (set_ and map_ options)
463 * fixed bug: potential seg fault when writing spool files because it
464 was not read properly
465 * multiple messages per connection now also if mail is sent directly
466 (same for local_nets is still missing, but I will use routes for these
467 anyway in the future)
468 * the queue will now be read in random order
469 * implemented multiple messages per connection (but only online
470 and if mail_host is defined)
471 * implemented rewriting of local parts in return path for online
472 delivery
473 * domain matching is no longer case sensitive (had to define
474 _GNU_SOURCE so that I could use FNM_CASEFOLD for fnmatch)
475 * added do_correct_helo option for routes
476 * fixed bug: corrected retrying hosts if one failed (connect.c).
477 0.0.1:
478 * fixed bug: seg fault when delivering online directly and there was
479 more than one rcpt to a single host.
480 * fixed bug: if mail was succesfully delivered in online mode to all
481 rcpts, and if there were additional (local) rcpts for which the mail
482 was not yet delivered, the mail was deleted from spool.
483 * rearranged smtp_out.c to prepare for multiple messages per connection
484 * log now shows the real host a message is sent to by SMTP (previously
485 it was the one looked for, now it is the one that was found by DNS)
486 * added NOOP, HELP and not recognized replies in smtp_in
487 * fixed bug: forgot to close dup_sock in accept_connect (listen.c)
488 * can now list the queue with the -bp option or when called as mailq
489 * debug_level is now configurable and -d option added
490 * corrected rfc821 address parsing and rearranged code
491 0.0.0:
492 * initial release
