This is another The only character affected by the ${quote_sqlite: operator is a single quote, which it doubles. + The SQLite library handles multiple simultaneous accesses to the database + internally. Multiple readers are permitted, but only one process can + update at once. Attempts to access the database while it is being updated + are rejected after a timeout period, during which the SQLite library + waits for the lock to be released. In Exim, the default timeout is set + to 5 seconds, but it can be changed by means of the sqlite_lock_timeout + option. + Note that you must set LOOKUP_SQLITE=yes in Local/Makefile in order to obtain SQLite support, and you will also need to add -lsqlite3 to the EXTRALIBS setting. And of course, you have to install SQLite on your host first. +PH/02 The variable $message_id is now deprecated, to be replaced by + $message_exim_id, which makes it clearer which ID is being referenced. + +PH/03 The use of forbid_filter_existstest now also locks out the use of the + ${stat: expansion item. + +PH/04 The IGNOREQUOTA extension to the LMTP protocol is now available in both + the lmtp transport and the smtp transport running in LMTP mode. In the + lmtp transport there is a new Boolean option called ignore_quota, and in + the smtp transport there is a new Boolean option called + lmtp_ignore_quota. If either of these options is set TRUE, the string + "IGNOREQUOTA" is added to RCPT commands when using the LMTP protocol, + provided that the server has advertised support for IGNOREQUOTA in its + response to the LHLO command. + +PH/05 Previously, if "verify = helo" was set in an ACL, the condition was true + only if the host matched helo_try_verify_hosts, which caused the + verification to occur when the EHLO/HELO command was issued. The ACL just + tested the remembered result. Now, if a previous verification attempt has + not happened, "verify = helo" does it there and then. + +PH/06 It is now possible to specify a port number along with a host name or + IP address in the list of hosts defined in the manualroute or + queryprogram routers, fallback_hosts, or the "hosts" option of the smtp + transport. These all override any port specification on the transport. + The relatively standard syntax of using a colon separator has been + adopted, but there are some gotchas that need attention: + + * In all these lists of hosts, colon is the default separator, so either + the colon that specifies a port must be doubled, or the separator must + be changed. The following two examples have the same effect: + + fallback_hosts = host1.tld::1225 : host2.tld::1226 + fallback_hosts = <; host1.tld:1225 ; host2.tld:1226 + + * When IPv6 addresses are involved, it gets worse, because they contain + colons of their own. To make this case easier, it is permitted to + enclose an IP address (either v4 or v6) in square brackets if a port + number follows. Here's an example from a manualroute router: + + route_list = * "
