Well, I no longer seem to be developing a phone system for The University
(hurrah!), so it must be time to try and move to Cyrus 2.3.
Is there any interest in trying to merge the following odds and ends
(either as is, or as options configured via imapd.conf):
HERMES_SCAN:
Implementation of the undocumented IMAP SCAN extension which PINE
uses for cross mailbox searches.
HERMES_PARTIAL_SQUAT
Run squatter on a consistent subset of mailboxes. Uses modulo
arithmetic on mailbox UniqueID to select the mailboxes to squat. For
example: "squatter -m 0 -M 10" squats 1/10th of all mailboxes.
HERMES_FIX_FUD
The fud dameon reports the time that a mailbox was last selected
by an IMAP client. The lastchange timestamp seems a more appropriate
thing to return when IMAP clients which use long running IMAP
connections (PINE, Mulberry) are involved.
HERMES_LMTP_EAT_BARE_CR:
It used to be fairly common for spam messages to contain \n\r
rather than \r\n sequences in messages headers.
Cyrus expands \n\r to be \r\n\r\n, effectively ending the message
headers. This is only a problem because spam scoring software
such as Mailscanner adds X-Spam-Score headers for Sieve to pick up.
These aren't much use if they end up in the body of the message.
HERMES_LMTP_AUTOCREATE
If a Sieve fileinto clause references a mailbox which does not
exist then automatically create it (if the user is allowed).
HERMES_FIX_PROCTITLE
Add proctitle support for Linux. Or at least the versions of
Linux that I commonly use: I'm not sure if t
HERMES_POP_LOG_VERBOSE
HERMES_IMAP_LOG_VERBOSE
HERMES_IPURGE_LOGGING
Log expunge events (and the number of messages expunged) so that when
someone moans that Cyrus has eaten their email we can at least
demonstrate that it was at the request of a mail client.
HERMES_LMTP_LOG_VERBOSE
Slightly more detail in lmtp log entries. Example:
Feb 14 15:36:17 cyrus-24 lmtpd[23684]: deliver:
<=
<>
-> user.dpc22.cyrus-devel
Just makes it easier to work out what has been delivered where.
A couple of patches for compatibility with the UW IMAP server,
unlikely to be of general interest:
HERMES_LMTP_QUOTACHECK
HERMES_APPEND_QUOTACHECK
A vanilla Cyrus will deliver the first message that takes a user
over quota. In contrast a UW server will only accept messages which
fit within the remaining quota. This has the advantage that a message
with a 10 MByte attachment doesn't block lots of small messages,
but on the other hand it may be less obvious to the user that they are
running out of quota.
HERMES_UIDL_COMPATIBILITY
Use POP3 UIDLs which are of the same format as the UW IMAP server.
