A kludge has been added to help with this. + Before calling hosts_ctl(), errno is set zero. If the result is "deny", a + 554 error is used if errno is still zero or contains ENOENT (which occurs + if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a + 451 error is used. + +PH/03 Add -lutil to the default FreeBSD LIBS setting. + +PH/04 Change PH/19 for 4.61 was too wide. It should not be applied to host + errors. Otherwise a message that provokes a temporary error (when other + messages do not) can cause a whole host to time out. + + Exim version 4.61 ----------------- @@ -115,6 +141,7 @@ PH/19 When calculating a retry time, Exim used to measure the "time since when small messages continue to be delivered.

This meant that they could be retried too + frequently, and not timed out correctly. + + (ii) Exim was setting the flag that allows error details to be returned + for LMTP errors on RCPT commands, but not for LMTP errors for individual + recipients that were returned after the DATA command. + +PH/53 This is related to PH/52, but is more general: for any failing address, + when detailed error information was permitted to be returned to the + sender, but the error was temporary, then after the final timeout, only + "retry timeout exceeded" was returned. Now it returns the full error as + well as "retry timeout exceeded". + +PH/54 Added control=allow_auth_unadvertised, as it seems there are clients that + do this, and (what is worse) MTAs that accept it. + +PH/55 Added the add_header modified to ACLs.

This was different to the case when no + redirection occurred. The value is now passed back in both cases. + +PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to + HAVE_SETCLASSRESOURCES because there are different APIs in use that all + use login_cap.h, so on its own it isn't the distinguishing feature.

This bug has + been fixed. However, if bounce_return_message is true and bounce_return_ + body is false, the headers that are returned for a non-SMTP message + include only those that have been read before the error was detected. + (In the case of an ACL rejection, they have all been read.) + +PH/69 The HTML version of the specification is now built in a directory called + spec_html instead of spec.html, because the latter looks like a path with + a MIME-type, and this confuses some software. + +PH/70 Catch two compiler warnings in sieve.c. + +PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The + function verify_get_ident() calls ip_connect() to connect a socket, but + if the "connect()" function timed out, ip_connect() used to close the + socket. However, verify_get_ident() also closes the socket later, and in + between Exim writes to the log, which may get opened at this point. When + the socket was closed in ip_connect(), the log could get the same file + descriptor number as the socket. This naturally causes chaos. The fix is + not to close the socket in ip_connect(); the socket should be closed by + the function that creates it. There was only one place in the code where + this was missing, in the iplookup router, which I don't think anybody now + uses, but I've fixed it anyway. + +PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as + well as to direct DNS lookups. Otherwise the handling of names in host + lists is inconsistent and therefore confusing. + Exim version 4.60 -----------------
