Re: [Dovecot] managesieve proxy cyrus
Does Squirrelmail try to use STARTTLS? Having full session traffic logs I don't think Squirrelmail is trying to use STARTTLS. But anyway I've tried to trace the sieve connection protocol, you could find it in the attachement. It's approximatively the same data, I've posted yesterday with extra protocol tcp/ip :) of when Squirrelmail is logging into Dovecot proxy and when logging into Cyrus proxy would be helpful (ngrep, wireshark, etc). If Squirrelmail uses STARTTLS, this doesn't really work though (but at least the logs will reveal that it is doing STARTTLS). Also if it is doing that, perhaps the issue is SASL PLAIN after all, since Dovecot proxy won't do STARTTLS to the Cyrus. Also if you set auth_debug=yes, what do you see in Dovecot logs when attempting to log in? Here is my dovecot log with auth_debug=yes : Jan 28 09:31:24 myservername dovecot: auth(default): client in: AUTH 3 PLAIN service=managesieve secured lip=127.0.0.1 rip=127.0.0.1 lport=2000 rport=42791 resp=hidden Jan 28 09:31:24 myservername dovecot: auth-worker(default): sql(imap2,127.0.0.1): query: SELECT NULL AS password, host, destuser, 'Y' as nopassword, 'Y' AS proxy FROM proxy WHERE user = 'imap2' Jan 28 09:31:24 myservername dovecot: auth(default): client out: OK3 user=imap2 host=138.138.138.138 destuser=imap2 proxy pass=hidden Jan 28 09:31:24 myservername dovecot: managesieve-login: Disconnected: user=imap2, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Jan 28 09:31:24 myservername dovecot: auth(default): new auth connection: pid=4760 Frame 1 (74 bytes on wire, 74 bytes captured) Arrival Time: Jan 28, 2009 09:31:24.796988000 Time delta from previous packet: 0.0 seconds Time since reference or first frame: 0.0 seconds Frame Number: 1 Packet Length: 74 bytes Capture Length: 74 bytes Protocols in frame: eth:ip:tcp Ethernet II, Src: Xensourc_1f:1f:1f (1f:1f:1f:1f:1f:1f), Dst: Dell_1e:1e:1e (1e:1e:1e:1e:1e:1e) Destination: Dell_1e:1e:1e (1e:1e:1e:1e:1e:1e) Address: Dell_1e:1e:1e (1e:1e:1e:1e:1e:1e) ...0 = Multicast: This is a UNICAST frame ..0. = Locally Administrated Address: This is a FACTORY DEFAULT address Source: Xensourc_1f:1f:1f (1f:1f:1f:1f:1f:1f) Address: Xensourc_1f:1f:1f (1f:1f:1f:1f:1f:1f) ...0 = Multicast: This is a UNICAST frame ..0. = Locally Administrated Address: This is a FACTORY DEFAULT address Type: IP (0x0800) Internet Protocol, Src: IP_proxy_dovecot (IP_proxy_dovecot), Dst: Ip_cyrus_server (Ip_cyrus_server) Version: 4 Header length: 20 bytes Differentiated Services Field: 0x00 (DSCP 0x00: Default; ECN: 0x00) 00.. = Differentiated Services Codepoint: Default (0x00) ..0. = ECN-Capable Transport (ECT): 0 ...0 = ECN-CE: 0 Total Length: 60 Identification: 0x7d21 (32033) Flags: 0x04 (Don't Fragment) 0... = Reserved bit: Not set .1.. = Don't fragment: Set ..0. = More fragments: Not set Fragment offset: 0 Time to live: 64 Protocol: TCP (0x06) Header checksum: 0xa5f8 [correct] Good: True Bad : False Source: IP_proxy_dovecot (IP_proxy_dovecot) Destination: Ip_cyrus_server (Ip_cyrus_server) Transmission Control Protocol, Src Port: 53996 (53996), Dst Port: sieve (2000), Seq: 0, Len: 0 Source port: 53996 (53996) Destination port: sieve (2000) Sequence number: 0(relative sequence number) Header length: 40 bytes Flags: 0x0002 (SYN) 0... = Congestion Window Reduced (CWR): Not set .0.. = ECN-Echo: Not set ..0. = Urgent: Not set ...0 = Acknowledgment: Not set 0... = Push: Not set .0.. = Reset: Not set ..1. = Syn: Set ...0 = Fin: Not set Window size: 5840 Checksum: 0x384f [correct] Options: (20 bytes) Maximum segment size: 1460 bytes SACK permitted Time stamp: tsval 1185633227, tsecr 0 NOP Window scale: 4 (multiply by 16) Frame 2 (74 bytes on wire, 74 bytes captured) Arrival Time: Jan 28, 2009 09:31:24.797024000 Time delta from previous packet: 0.36000 seconds Time since reference or first frame: 0.36000 seconds Frame Number: 2 Packet Length: 74 bytes Capture Length: 74 bytes Protocols in frame: eth:ip:tcp Ethernet II, Src: Dell_1e:1e:1e (1e:1e:1e:1e:1e:1e), Dst: Xensourc_1f:1f:1f (1f:1f:1f:1f:1f:1f) Destination: Xensourc_1f:1f:1f (1f:1f:1f:1f:1f:1f) Address: Xensourc_1f:1f:1f (1f:1f:1f:1f:1f:1f) ...0 = Multicast: This is a UNICAST frame ..0. = Locally Administrated Address: This is a FACTORY DEFAULT address Source: Dell_1e:1e:1e

Does anybody here have configure a sieve proxy to do this ? Your setup is a bit odd. I haven't tried this ever and doubt anyone else has. The proxying feature is mainly implemented with Dovecot back-ends in mind. In an ideal world this should work however, so there is a possibility that the Dovecot proxy is not working properly. Or is it a normal behavior and dovecot sieve proxy can't speak with cyrus sieve ? Theoretically, this setup should be possible. However, the protocol specification is unfortunately not always followed to the letter. Also, Cyrus possibly does not allow you to login with the SASL PLAIN mechanism (the only one supported for proxying now). This seems unlikely though, since the IMAP proxy does work.

Re: [Dovecot] benchmark dovecot
Mark Zealey a écrit : Thanks; these look interesting. We have a similar nas setup but we have 2 frontend dovecot servers connecting to it and store the indexes over nfs. Could you please tell me how have you done this configuration ? 2 frontend dovecot proxy with 10 dovecot mda ? We are looking for such a configuration : 2 mda frontend with maybe an active and a passive one ! We also have around 10 mail servers running deliver to try to keep the indexes on the nfs store up-to-date. Have you done any tests with the speed of multiple boxes each maintaining a local index of the mailbox? No sorry I suspect in this case keeping indexes on nfs would be the best bet but I don't have anything to substantiate that claim... Also one thing to note with storing things on nfs is that there are a large number of broken kernels out there (they issue about 10* more nfs lookup requests than they should) - centos 5.1 had these issues iirc (though the centosplus kernel and centos 5.2 did fix it). Good thing to know, I'll try to change kernel before my migration ! Always give it a good test before you change the kernel on your server... I assume you are using nfs3; has anyone tried using heavily loaded nfs4 and seeing if any better performance can be achieved? Another thing - I found that dovecot's pop3 implimentation is worse than courier's over nfs (wait state on our boxes is significantly increased).

cyrus2courier 1.5.ts should work with Cyrus 2.2.12 if the seen (and

must first be converted using cvt_cyrusdb(8).
My last try has nothing good :
cyrus2courier-1.5-dev : segfault
cyrus2courier-1.5-ts : segfault
I dont understand why ? But it's happening only with -e my_seen_dir option!
However, for our conversion, we've written our own cyrus2dovecot which
also supports skiplist databases (amongst another few features not
provided by the other tools):
http://cyrus2dovecot.sw.fu-berlin.de/
I've tried this one too and I'm stuck too :

I've red the perl code and found this :
if (-e $boxpath/cyrus.header and -e $boxpath/cyrus.index) {
//code
} else {
#
# The folder we're in is not in a Cyrus mailbox.
However, we
# don't simply return here because this folder might contain
# other folders which might be Cyrus mailboxes (unless
we're in
# the INBOX, in which case something is going wrong).
#
error('No Cyrus INBOX at:', $boxpath) if $box eq 'INBOX';
debug(Skipping $boxpath as it's not a Cyrus mailbox.);
$mailfolder = 0;
}
But I'm sure cyrus.header and cyrus.index exist.
Any idea (maybe this is a format problem because even cyrus2courier is
doing segfault)

I've just tested a transition and I'm happy to see it keeps all flags (seen/unseen too) and timestamp but as cyrus2courier, I can't see my inbox sub folders although I could see them (full) on the File System? Certainly for all new servers I would STRONGLY recommend some sort of virtualisation option (I use linux vservers, lots of other options available). This makes it fantasically easy to boot up (say) three instances of your target software installation, perhaps all with different configuration options and compare them easily. I used this as a solution to migrate from Courier and also recently when I was migrating from 32bit to 64bit guests - essentially you spin up your new guest, get it all ready, test it like made and then in a couple of seconds you can down the live guest and boot up the new guest. I separate out all signficant data from the guest partition so try to keep the actual installations under a couple hundred MB each (even that feels bloated, but hey) and this makes it simple to boot up a copy of a guest to test some change without having to copy too much I personally picked dovecot because I worried about the horror stories I read about with cyrus. However, both are clearly the two best options available for opensource solutions right now and both are used in large installations so you should be very happy with either. With regards to functionality it would appear (I don't use cyrus) that cyrus has more admin tools to do stuff, but Dovecot is built to be more hackable, for example you can easily run a script before each (imap, etc) login and hence do some very advanced stuff through that route. Plugins also appear to be quite easy to write to extend dovecot in new directions On the cyrus list they mentioned email retention policies. Now some people are going to say that this is really a job for the MTA (postfix/sendmail/etc). However, you have some plugins which might get you partly towards solving that need, but nothing out of the box which would give you a cast iron (stand up in court) kind of archiving control.

First of all : forgive me for my poor English Hello all, I've to compare cyrus with dovecot for my work. Because these are the only solutions that could fit our needs. Unfortunately I really don't know a lot about dovecot and I would like to have some of its assets. Here are the properties of the versus table I've done : dovecot cyrus Installation: Update: Migration from cyrus : Migration from dovecot : functionalities : Management : Local Delivery : availability : Security : Indexes management : NFS compatibility : Scalability : Configuration : interoperability : Sieve filter : Documentation : Quota capability : Performance : IMAP capability : So I know this can scared you, but If you have some asset for dovecot, It could be great and a lot more FAIR !! Thank you in advance for your advice. begin:vcard fn:Mathieu Kretchner n:Kretchner;Mathieu org:INRIA;Syslog adr;dom:;;2007 route des lucioles - BP93;Sophia Antipolis;;06902 CEDEX email;internet:[EMAIL PROTECTED] tel;work:04 92 38 76 67 x-mozilla-html:FALSE version:2.1 end:vcard

Timo (and other users) doesn't leave any (non trivial) question unanswered, wiki is full of useful info, important bugs are fixed quick (follow mercurial repo) and new versions are released often - dovecot is one of best supported open source projects I know... regards Indeed It's a good point for us that this is a big project with a lot of involved developers ! But, at present, we need to have a secure / reliable / fast with all the properties that must fit a real e-mail server in order to support our new e-mail IMAP architecture, so the question is (because we have only 2 options) Why should I choose dovecot instead of Cyrus ?

Because it is secure / reliable / faster than cyrus - and *much* easier to install/configure? You'll have more chance of a specific answer if you provide more specifics as to what 'properties that must fit a real email server' means to you. So here is my next environment : how many mailbox ? 5000 how many users ? 6000 what is in use now ? Cyrus what kind of access ? IMAP(s), POP3(s), webmail how many server ? 2 (how to configure this with dovecot ? hearthbeat ? is it better with 1 big hardware ? ) Database user ? LDAP Mail DB ? Cyrus maildir Capability ? Sieve / Quota High Performance without hacking conf files ! begin:vcard fn:Mathieu Kretchner n:Kretchner;Mathieu org:INRIA;Syslog adr;dom:;;2007 route des lucioles - BP93;Sophia Antipolis;;06902 CEDEX email;internet:[EMAIL PROTECTED] tel;work:04 92 38 76 67 x-mozilla-html:FALSE version:2.1 end:vcard
