Re: cyrus-murder: backend and frontend/proxy on the same machine?
Hello all.
I must conclude that all combined configurations of Cyrus Murder
servers do not work. Or, more exactly, I did not manage to make them
work despite of many hours of tests and meditation.
frontend+backend combination (aka config: unified) seems to be
completely broken. It is really unable to distinguish local and remote
mailboxes in the single combined database and pushes everything back to
master, with endless database growth. I wrote about it few weeks ago in
same thread.
frontend+master combination behaves much better. Nearly all things
work fine: folder access, folder renaming, sieve access. The only broken
thing is subfolder mailbox creation; any user-level Create command at
a frontend is not forwarded to a backend but is denied instantly with
Invalid partition diagnostics. Basic debugging shows that the
partition is really invalid because proxyd tries to interpret a
networked server!partition path as a local partition name and to find
this name in local imapd.conf.
Feb 11 12:58:05 mail imap[18506]: Partition pharmacy.office.rct-int!default
Feb 11 12:58:05 mail imap[18506]: IOERROR: creating directory (null):
Permission denied
So, it looks like that the only working solution is based on -C option
and virtual interfaces or other tricks. If we really need to combine
functions in one box, we should use different imapd*.conf and
different configdirectory: for all three instances - frontend, backend
and master. After that everything works fine.
My setup:
Master+Frontend: two indepentent mupdate instances, one imapd.
SERVICES {
mupdate_master cmd=/usr/local/cyrus/bin/mupdate -m -C
/etc/imap_master.conf listen=10.0.0.2:3905 prefork=1
mupdate cmd=/usr/local/cyrus/bin/mupdate -C
/etc/imap_frontend.conf listen=10.0.0.4:3905 prefork=1
imapcmd=/usr/local/cyrus/bin/proxyd -s -C
/etc/imap_frontend.conf listen=imaps prefork=2
sieve cmd=timsieved -C /etc/imap_frontend.conf
listen=10.0.0.4:sieve prefork=0 maxchild=100
}
Frontend+backend: two independent imapd instances, one mupdate.
SERVICES {
imapcmd=imapd -p 2 listen=10.0.4.1:imap
prefork=3 maxchild=200
imaps cmd=proxyd -s -C /etc/imap_frontend.conf
listen=imaps prefork=1 maxchild=100
mupdate cmd=mupdate -C /etc/imap_frontend.conf
listen=10.0.4.1:3905 prefork=1
lmtpcmd=lmtpd -a listen=10.0.4.1:24 prefork=0
maxchild=20
}
Tested with Thunderbird and Squirrelmail clients.
NB: In this specific setup lmtp does not use murder capabilities because
MTA always knows exact backend from LDAP directory. And the whole
purpose of Murder is to join shared folders from different servers and
locations into one list in one IMAP account. No any load balance, etc.

Is it possible with cyrus to reject emails with large attachments and inform the sender for the rejection? As stated, normally done at the MTA level. But note also, normally done by total message size, not attachment size. If you have to analyze mime parts and measure the size of each one, half the battle is lost already, that is the sender already transmitted the large message and you had to store it in a spool file and parse it. At MTA level, if you and the sender both use ESMTP, your MTA can state its maximum message size in the ehlo response, and the sender's MTA can see that and not even send the message. That is the best outcome. If the sender does not use ESMTP, it wastes time sending the entire message, but you can still reject quickly. The sender's MTA will create the bounce notice, or do whatever else it does when mail can't be delivered. The Cyrus system should not send a bounce. It should only accept or reject, and the sending MTA should handle notifying the sender.

Re: Reject large emails
2008/2/12 Nikos Gatsis [EMAIL PROTECTED]: First, this is the king of stuff you should setup at SMTP level to reject the message before it enter the server. Does cyrus send a rejection message to the sender? No, cyrus cannot send such a message. When a system accept an email via SMTP or LMTP protocol, this is its responsibility to warn the sender if it cannot handle it further! If it choose to reject it, this is then the responsibility of the system that connected to it. Then look your SMTP documentation. Regards.

Non-ASCII chars in MAIL FROM envelope
Hi, Running postfix as an MTA I have the problem that postfix accepts mail with non-ASCII chars in MAIL FROM envelope and cyrus-imapd's lmtpd rejects them with 501 5.5.4 Syntax error in parameters. From what I understand 8bit envelopes are allowed according to newer RFC's and I'm wondering if it's correct that cyrus-imapd blocks them if they are found in MAIL FROM, not RCPT TO? I know it's possible to use check_sender_access in postfix to stop those mails from being accepted, but it seems it could still block legitimate mails despite that fact that those from adresses may be 99.9% spam. How do others deal with this issue?
