Berkeley DB create and read buffer size controls. Files:

Cleanup: simplified the hash/btree cache management code.
The caches are now per table instead of shared, and the
default read cache size is reduced to 128 kBytes. File:
util/dict_db.c.
20020508
Bugfix: close an obscure source routing relaying loophole
involving postfix-style virtual domains. Problem reported
by Victor Duchovny. File: smtpd/smtpd_check.c.
Bugfix: mail_addr_map() used the "wrong" @ character in
addresses with multiple @. Victor Duchovny. File:
global/mail_addr_map.c.
Bugfix: for address localpart quoting, now quote @ as a
special character everywhere, except when resolving addresses.
Previously, the @ was nowhere quoted as a special character,
not even in SMTP commands. Files: global/quote_82[12]_local.c
and clients.
Open problems:
Low: sendmail does not store null command-line recipients.

@ -95,13 +95,18 @@ Tweaking performance
Postfix provides two configuration parameters that control how much
buffering memory Berkeley DB will use.
- berkeley_db_create_buffer_size (default: 16 MBytes). This setting
is used by the postalias and postmap commands. For "hash" files
performance degrades rapidly unless the memory pool is O(file size).
For "btree" files peformance is good with sorted input even for
small memory pools, but with random input degrades rapidly unless
the memory pool is O(file size).
- berkeley_db_create_buffer_size (default: 16 MBytes per table).
This setting is used by the postalias and postmap commands. For
"hash" files, create performance degrades rapidly unless the memory
pool is O(file size). For "btree" files, create peformance is good
with sorted input even for small memory pools, but with random
input degrades rapidly unless the memory pool is O(file size).
- berkeley_db_read_buffer_size (default: 256 kBytes). This setting
is used by all other Postfix programs. The buffer size is adequate
for reading.
- berkeley_db_read_buffer_size (default: 128 kBytes per table).
This setting is used by all other Postfix programs. The buffer size
is adequate for reading. If the cache is smaller than the table,
random read performance is hardly cache size dependent, except with
btree tables, where the cache size must be large enough to contain
the entire path from the root node. Empirical evidence shows that
64 kBytes may be sufficient. We double the size to play safe, and
to anticipate changes in implementation and bloat.

local_recipient_maps in the main.cf file. That could interfere with
content filtering.
The SMTP server is configured to use a different hostname in the
greeting message (this is necessary for testing when I simply use
no filtering program and let the SMTP content filtering interfaces
talk directly to each other).
The "-o myhostname=localhost.domain.name" avoids a possible problem
if the content filter is picky about the hostname that Postfix
sends in SMTP server replies.
The "-o disable_dns_lookups=yes" turns off unnecessary DNS lookups
that would only slow things down.
The "-o cleanup_service=cleanup2" specifies that mail received via
the secondary SMTP server should be send into the cleanup2 service.
As the master.cf entry above shows, the cleanup2 service is like
the normal cleanup server, but with some features turned off: no
processing of header patterns, and no processing of body message
patterns. This can save you some precious CPU cycles.
