Aktuelles im Detail

Weasel, a mail server for OS/2, has now been updated to version 1.81.
You can obtain it from
ftp://ftp.pmoylan.org/Weasel/weasel1.81.zip
or from
www.pmoylan.org/pages/os2/weasel.html
of from Hobbes.

Because the many intermediate versions since version 1.80 have been made
available only to members of the Weasel mailing list, the list of
changes is rather large.

LIST OF CHANGES since version 1.80

Version 1.81 (8 Sep 2012)
Fixed: Weasel was not unhiding the files in the
'forward' directory on startup.
LoadINI and DumpINI are no longer included in the Weasel
distribution. You have to download GenINI separately.
(Luckily, GenINI does not often get updated.)
The "fetch last" POP option is now obsolete. POP clients
now see all of the messages on the server, rather
than the first or last 512 messages.
Fixed: an uninitialised pointer that was causing a
crash on some POP fetches.
Added log message that identifies the domain that an
SMTP outbound thread is trying to reach.
Fixed a stack overflow on USER command.
Some extra log messages for SMTP outbound.
Removed the obsolete "POP fetch starts with most recent"
checkbox from the Setup program.
New policy: 5-second delay added before closing the
connection from a blacklisted client.
Setup now accepts new command-line parameters. See
the manual for details.
Policy change to accommodate servers that do
greylisting: when sending out mail, we don't try
the relay backup host until the fifth retry.
Removed some obsolete code, cleaned up the POP data
structures.
Change to the interval between retries.
For SMTP outbound mail, authentication is not used
unless there is a relay host. The Setup notebook
and manual have been updated to make this clearer.
Fixed: when a backup relay is configured, the relay
was not always used, so some items remained
undeliverable.
Added: extra log line to show whether SMTP authentication
for outgoing mail was successful.
Removed code for the obsolete "POPFetchLatest"
option, an option that allowed fetching mail in
a nonstandard order.
Some minor changes to logging.
Fixed: crash on USER command when TNI file used.
Fixed: the next message number was not being updated
in INI or TNI file.
Fixed: in TNI mode, a zero-length WEASEL.INI was
being created if it didn't already exist.
Startup operations more carefully sequenced to take
into account task interdependencies.
Fixed: crash if INI or TNI file was missing.
New approach to dynamic control of the number of
Send_NN tasks.
Fixed: the wrong number of Send_NN tasks were
being started.
Change: you can now change the number of these tasks
(in Setup) without having to restart Weasel.
Build level information added to weasel.exe. (So
you can now find out its version number by
running "bldlevel weasel.exe".)
Fixed: the transaction log was not being cleanly closed on exit.
Policy change: transaction log now updated every minute
instead of once every 15 minutes.
Fixed: error when trying to write a number in too
small a field size.
Fixed: crash caused by missing CRLF in input line
or input line that is longer than the standards allow.
Fixed: we accept neither mail nor logins for an
account that has been marked inactive.
New protection against dictionary attack: when there
are too many password errors, the client IP
address is blocked for 10 seconds.
Misc changes to reduce stack usage.
The "status" thread that was putting three counts to
the log has been removed. It was created to track
down a memory leak, but it never found one.
New script "ban.cmd" added to tools directory on web site.
(But not to zip file.)
Converted many "value" string parameters to "var".
Corrected a spelling error in looking up "OurHostName"
in the INI or TNI file.
Fixed: incorrect handling of option to forward mail
for a local user to another address.
Minor update to kernel stack shifting code.
Fixed: Setup was crashing if SETUP.INI did not exist.
Updated Spanish language file.
Fixed small memory leak in TNI handling.
Added log message to show how much memory has been
allocated for TNI data (but only if extra logging
is specified and we are in TNI mode).
Added a "-i" parameter to explicitly turn off
TNI mode.
Fixed: Setup crash in TNI mode if MailRoot changed.
Added file WEASEL.FMT, for more readable layout of
TNI files if DumpINI is used.
Added check for accessibility of DOMAIN.INI
when clearing a recipient list.
Fixed: after dropping a new font on a Setup
notebook, the notebook sometimes reverted to
the old font on exit.
For consistency, Setup now saves its own options in
Setup.TNI if running in TNI mode. Note that this
implies that you can have two independent sets
of fonts and window positions depending on whether
you start Setup in INI or TNI mode.
Added logging of heap usage, as a check for
memory leaks.
Removed OldDumpINI and OldLoadINI from the distribution.
These programs are now officially obsolete.
Added exceptq handling.
Fixed: Two semaphore leaks.
