Re: command line deletion of files
You're the reason we can't have nice things :( rm + reconstruct will bite you one upgrade for sure. A dry run option to ipurge sounds like a great idea. We just always use IMAP to do admin on Cyrus, but I can see a case for improving ipurge.

Re: command line deletion of files
We use a perl scrip that does similar process to delete mass phishing or
malware email messages from the mail spool. The script locates the
sequence number for the message based on the message ID/filename, and
then issues the IMAP delete and expunge commands.
Relevant section of code below (This is called from a subroutine that
uses File::Find to locate the files in the file system, but it could be
called with a simple list of files.) Advantage over ipurge is that this
is not based on date or size but a specific set of files.
Enjoy,
John

Good morning,

Would it be proper to
rm -rf /var/spool/imap/u/username/mailbox/4321.
then
reconstruct -rf user.username
Or is there a more "proper" way using cyrus?

I've found mutt to be useful for this type of maintenance, which can sort messages by size, and can delete ranges. If you don't have access to user passwords, set up a 'proxyservers' authz identity to access their mailboxes. -- Dan White Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus

Not sure about deleting a single message but you can use ipurge to delete messages based on size. Good to use in a script to parses the mail spool. IPURGE(8) IPURGE(8) * NAME ipurge - delete mail from IMAP mailbox or partition based on age or size SYNOPSIS ipurge [ -f ] [ -C config-file ] [ -x ] [ -X ] [ -i ] [ -s ] [ -o ] [ -d days | -b bytes | -k Kbytes | -m Mbytes ] [ mailbox-pattern... ] DESCRIPTION Ipurge deletes messages from the mailbox(es) specified by mailbox-pattern that are older or larger than specified by the -d, -b, -k or -m options. If no mailbox-pattern is given, ipurge works on all mailboxes. If the -x option is given, the message age and size MUST match exactly those specified by -d, -b, -k or -m. The are no default values, and at least one of -d, -b, -k or -m MUST be specified. Ipurge by default only deletes mail below shared folders, which means that mails in mailbox(es) below INBOX.* and user.* stay untouched. Use the option -f to also delete mail in mailbox(es) below these folders. Ipurge reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C. OPTIONS -f Force deletion of mail in all mailboxes. -C config-file Read configuration options from config-file. -d days Age of message in days. -b bytes Size of message in bytes. -k Kbytes Size of message in Kbytes (2^10 bytes). -m Mbytes Size of message in Mbytes (2^20 bytes). -x Perform an exact match on age or size (instead of older or larger). -X Use delivery time instead of Date: header for date matches -i Invert match logic: -x means not equal, date is for newer, size is for smaller -s Skip over messages that have the \Flagged flag set. -o Only purge messages that have the \Deleted flag set.
