[Dovecot] Recommended Groupware?
Hi, is there a recommended groupware (email + calendar + address book + syncing with mobile devices) on top of an existing dovecot installation? Most existing commercially supported groupwares come with their own mail storage engine. I would like to keep dovecot as the email storage engine because of the maildir format which greatly helps with backup & restore. Regards -- Robert Sander

Hi!
If you want to purge emails that have been marked as deleted in
Maildirs, use something like this:
find /var/spool/vmail/host1/user -name '*:2,*T*' -mtime +7 -exec rm -fv {} \;
This deletes all emails older than 7 days which are marked as deleted
(flag T in Maildir format).
We are using this for quite a while and have seen no problems with
dovecot imapd.
Greetings

[Dovecot] IMAP Proxy and Namespaces
Hi! Is it possible to combine these two features of dovecot, i.e. to have a specific namespace that proxies to another IMAP server? Greetings -- Robert Sander
[Dovecot] namespace prefix issue with avelsieve
Hi!
I am currently testing a setup with dovecot's lda, the cmusieve plugin,
pysieved and the avelsieve plugin for squirrelmail.
The issue I am stumbling upon is that avelsieve is generating folder
names including the namespace prefix when creating "fileinto" rules.
E.g.:
A rule:
If the header "Precedence" contains "bulk", then file it into
the folder INBOX.bulk. Also keep a copy in INBOX, marked as deleted.
translates into sieve:
require
["fileinto","reject","vacation","imapflags","relational","comparator-i;ascii-numeric","regex","notify"];
if
header :contains "Precedence" "bulk"
{
fileinto "INBOX.bulk";
addflag "\\Deleted";
keep;
}
But what happens when a matching email is delivered is that a new
mailbox ".INBOX.bulk" in the user's Maildir is created. I.e. the email
is not delivered to ~/.Maildir/.bulk as intended, but into
~/.Maildir/.INBOX.bulk, creating the new folder on the fly.
The same happens when trying to fileinto folders from other namespaces.
It seems that either avelsieve is generating "too much" and should
remove the prefix (at least for INBOX) or dovecot's deliver is not able
to use the namespaces definition in dovecot.conf correctly when
interpreting sieve's fileinto directive.
Did I miss something? This is the dovecot.conf in use:

[Dovecot] dovecot scaling issue?
Hi! We are running dovecot-imapd on Debian sarge out of the backports.org packages (version 1.0.rc15-1~bpo1). We have ~ 80 clients using secure IMAP. I understand that imap-login has to run for every SSL connection. Thus I already increased the max value for the number of imap-login processes. But unfortunately dovecot is unresponsive from time to time. Where can I tune the installation? Do I need to upgrade to 1.0.0, for which no backported packages exist for Debian sarge? This is the output of dovecot -n: log_timestamp: %Y-%m-%d %H:%M:%S listen: *:143 ssl_listen: *:993 ssl_cert_file: /etc/courier/imapd.pem ssl_key_file: /etc/courier/imapd.pem disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_processes_count: 12 login_max_processes_count: 512 verbose_proctitle: yes mail_location: maildir:~/.Maildir:INDEX=/var/cache/dovecot/INBOX.%u:CONTROL=/var/cache/dovecot/INBOX.%u mail_full_filesystem_access: yes maildir_stat_dirs: yes maildir_copy_with_hardlinks: yes namespace: type: private separator: . prefix: INBOX. inbox: yes namespace: type: public separator: . prefix: shared. location: maildir:~/.Maildir/shared:INDEX=/var/cache/dovecot/shared.%u:CONTROL=/var/cache/dovecot/shared.%u auth default: verbose: yes passdb: driver: passwd userdb: driver: passwd Homedirectories are on NFS, /var/cache/dovecot is a local filesystem. Clients are mostly Thunderbird, where max connection to IMAP server is set to 5.
