Change log file for Exim from version 4.21
-------------------------------------------
21. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
It is now set to "smtps".
+22. $host_address is now set to the target address during the checking of
+ ignore_target_hosts.
+
+23. When checking ignore_target_hosts for an ipliteral router, no host name was
+ being passed; this would have caused $sender_host_name to have been used if
+ matching the list had actually called for a host name (not very likely,
+ since this list is usually IP addresses). A host name is now passed as
+ "[x.x.x.x]".
+
+24. Changed the calls that set up the SIGCHLD handler in the daemon to use the
+ code that specifies a non-restarting handler (typically sigaction() in
+ modern systems) in an attempt to fix a rare and obscure crash bug.
+
+25. Narrowed the window for a race in the daemon that could cause it to ignore
+ SIGCHLD signals. This is not a major problem, because they are used only to
+ wake it up if nothing else does.
+
+26. A malformed maildirsize file could cause Exim to calculate negative values
+ for the mailbox size or file count. Odd effects could occur as a result.
+ The maildirsize information is now recalculated if the size or filecount
+ end up negative.
+
+27. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
+ support for a long time. Removed HAVE_SYS_VFS_H.
+
+28. Installed the latest version of exipick from John Jetmore.
+
+29. In an address list, if the pattern was not a regular expression, an empty
+ subject address (from a bounce message) matched only if the pattern was an
+ empty string. Non-empty patterns were not even tested. This was the wrong
+ because it is perfectly reasonable to use an empty address as part of a
+ database query. An empty address is now tested by patterns that are
+ lookups. However, all the other forms of pattern expect the subject to
+ contain a local part and a domain, and therefore, for them, an empty
+ address still always fails if the pattern is not itself empty.
+
+30. Exim went into a mad DNS loop when attempting to do a callout where the
+ host was specified on an smtp transport, and looking it up yielded more
+ than one IP address.
+
Exim version 4.43
