(for 8.6.3)
|

|
The following are bugs or deficiencies in sendmail that I am aware of
|
|
|
|
|
but which have not been fixed in the current release. You probably
|
|
|
|
|
want to get the most up to date version of this from FTP.CS.Berkeley.EDU
|
|
|
|
|
in /ucb/sendmail/KNOWNBUGS.
|
|
|
|
|
|
|
|
|
|
* "SYSERR: openmailer(local): fd 1 not open" message
|
|
|
|
|
|
|
|
|
|
File descriptor 1 (standard output) should not be closed during normal
|
|
|
|
|
processing. This is checked periodically, and sometimes this condition
|
|
|
|
|
is found and this message is produced. Sendmail repairs the problem,
|
|
|
|
|
and the mail is still delivered, but I still don't know why it happens.
|
|
|
|
|
(There was a bug that was fixed in 8.6.beta.13 that might be related,
|
|
|
|
|
but I think this bug still exists.)
|
|
|
|
|
|
|
|
|
|
* Null bytes are not handled properly.
|
|
|
|
|
|
|
|
|
|
Sendmail should handle full binary data. As it stands, it handles
|
|
|
|
|
any value from 0x01-0xFF in the body and 0x01-0x80 and 0xA0-0xFF in
|
|
|
|
|
the header. Notably missing is 0x00, which would require a major
|
|
|
|
|
restructuring of the code -- for example, almost no C library support
|
|
|
|
|
could be used to handle strings.
|
|
|
|
|
|
|
|
|
|
* Route-addrs missing angle brackets.
|
|
|
|
|
|
|
|
|
|
There are cases where route-addrs do not get angle brackets around them,
|
|
|
|
|
such as in the "-r" flag on mailers or in the From_ line created when
|
|
|
|
|
mailing to files.
|
|
|
|
|
|
|
|
|
|
* Duplicate error messages.
|
|
|
|
|
|
|
|
|
|
Sometimes identical, duplicate error messages can be generated. As
|
|
|
|
|
near as I can tell, this is rare and relatively innocuous.
|
|
|
|
|
|
|
|
|
|
* No "exposed users" in "nullrelay" configuration.
|
|
|
|
|
|
|
|
|
|
The "nullrelay" configuration hides all addresses behind the mail
|
|
|
|
|
hub name. Some sites might prefer to expose some names such as
|
|
|
|
|
root. This information is always available in Received: lines.

|
|
|
* $c (hop count) macro improperly set.
|
|
|
|
|
|
|
|
|
|
The $c macro is supposed to contain the current hop count, for use
|
|
|
|
|
when calling a mailer. This macro is initialized too early, and
|
|
|
|
|
is always zero (or the value of the -c command line flag, if any).
|
|
|
|
|
This macro will probably be removed entirely in a future release;
|
|
|
|
|
I don't believe there are any mailers left that require it.
|

|
|
|
* If you EXPN a list or user that has a program mailer, the output of
|
|
|
|
|
EXPN will include ``@local.host.name''. You can't actually mail to
|
|
|
|
|
this address. It's not clear what the right behaviour is in this
|
|
|
|
|
circumstance.
