Hi Simon & Matthias Thanks for your great work! We're currently testing the version from the mercurial repository and it works so far without any issue (SUSE Linux Enterprise Server 11SP4). As it seems to be very stable (after some tests) we deployed it to our productive environment with a current workload of about 5000 concurrent user to further test the stability. We'll still keep an eye on it... Kind regards Roman

Debian source package Disabling SSLv3 patch

by Marcus Schopen

Hi Simon, is there a Debian source package to build a package with the newest "Disabling SSLv3"-patches? I checked your launchpad repo https://launchpad.net/ubuntu/+source/perdition but I'm not sure, if this is the newest version form the Mercurial repo. Ciao Marcus

[PATCH 0/3 v2] Configuration of more SSL/TLS protocol optitions

by Simon Horman

Hi, this short series allows the configuration of more SSL/TLS protocol options at run time. * Provides options to set the minimum and maximum SSL/TLS protocol version. The new default is that SSLv3 and earlier are disabled. SSLv2 may not be enabled. * Provides an options to allow compression. The new default is that compression is disabled. * Provides an option to disable server cipher preference. The new default is to set server cipher preference. Thanks to Matthias Hunstock for his patch which provided the basis for this series. Review and testing would be appreciated. Changes since RFT (v1): * Enforce SSLv3 minimum version * Add compression and server cipher preference patches

Disabling SSLv3

by Epiontis IT

Hello Xavier, did you have any success disabling SSLv3? I would like to disable any old ciphers and turn on Forward Secrecy. Do you have experience with this and perdition? Thank you, Alex From: Xavier Garcia <xavi.garcia <at> gmail.com> Subject: Re: Disabling SSLv3 <http://news.gmane.org/find-root.php?message_id=20141031133121.GB53613%40bea…> Newsgroups: gmane.mail.perdition.user <http://news.gmane.org/gmane.mail.perdition.user> Date: 2014-10-31 13:31:23 GMT (43 weeks, 1 hour and 45 minutes ago) Hi, AFAIK, this enables STARTTLS in the port instead of starting a purely encrypted connection. nc -vv imapproxy01i 993 Connection to imapproxy01i 993 port [tcp/imaps] succeeded! * OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES * MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE * LOGIN-REFERRALS STARTTLS LOGINDISABLED] perdition ready on * imapproxy01i 00028de7 I haven't tested but I think this may not change the list of accepted cyphers. After reading the manual and some messages in the list, it seems that all references to TLS in the configuration are aiming at STARTTLS and the only way to change the valid ciphers is with *ssl_listen_ciphers* and *ssl_outgoing_ciphers*. Am I mistaken?

default server answer when using mysql lookups

by Jack Snodgrass

I have got perdition 2.1 setup and configured to do mysql lookups. IF a user is not found... .... status="failed: Could not determine server" I'd like to have a default/fallback server to use. Is that possible... I was thinking that maybe a mapping from: popmap.re might work.. but it doesn't seem like it looks at BOTH the mysql entry and the popmap.re entry. I am wanting to be able to ONLY list in the mysql table certain users that are on 1 imap server and have all other request go to our main imap server. Thanks - jack -- *jack* - Southlake Texas - http://mylinuxguy.net <http://mylinuxguy.net/>

ipv6 question

by Joe Pruett

i have a system that has both ipv4 and ipv6 addresses configured in dns, but if i use that name as the bind address for perdition, it seems to only bind to the v6 version. for now i have hacked things by using separate names, but i'd like to have a single name for both v4 and v6. am i missing some obvious way to force perdition to listen to both?

How to sort out ONE fixed IP serving several VMs

by Stephen Liu

Hi all, I have following problem: Host Ubuntu 14.04 desktop VMs Ubuntu 14.04 desktop/server edition VirtualBox I have several websites running on VMs, each with its own domain/subdomain and internal IP address. But I have only one Fixed IP/External IP. Could Perdition help me out? If YES please advise where can I find relevant document of its setup? All VMs are Apache server running WordPress. My problem is I have only ONE Fixed IP. I can create many internal IPs on router. Several years ago I made use of Perdition to setup several mail servers on VMs but served with only ONE Fixed IP. It worked seamlessly. All emails were delivered to their own servers. Maybe I can dig up the respective documents on my database. But I have no idea whether it also work on web-server? Thanks Regards satimis

Unable to get mail from outlook.com and gmail.com

by Miguel Castellanos

Hello everyone! I have successfully set up a perdition server which acts as a proxy to pop3 servers running in virtual machines. I use the pop3s protocol to get the emails. I can get mail using Thunderbird in Linux and Outlook in Windows, however Outlook.com and gmail.com cannot communicate with the perdition server: Please take a look at the perdition log file: perdition.pop3s[15859]: Connect: 65.55.41.7:58616->X.X.X.X:995perdition.pop3s[15859]: SSL connection using AES256-SHAperdition.pop3s[15859]: SELF: "+OK POP3 perditon ready on X.X.X.X 0002937a\r\n"perdition.pop3s[15859]: CLIENT: ""perdition.pop3s[15859]: token_read: token_fill_bufferperdition.pop3s[15859]: read_line: token_readperdition.pop3s[15859]: pop3_in_get_auth: read_lineperdition.pop3s[15859]: main: protocol->in_get_authperdition.pop3s[15859]: Fatal Error reading authentication information from client 65.55.41.7:58616->X.X.X.X:995: Exiting child It seems that the SSL connection works (SSL connection using AES256-SHA) but Outlook.com and gmail.com are not able to authenticate.

Chain perdition server

by AURELIEN DELCROIX

Hi all, I Would like to know if it's possible to chain perdition server between them. For example I have some server on my LAN who have to POP some gmail box. In order to secure the access I would like to install two perdition servers : the first one in the LAN and the second one in DMZ (Server->Perdition_LAN->Perdition_DMZ->Gmail server). I have successfully installed the server on the DMZ and it works, but when the one the LAN try to reach it, Ive got the following message : Perdition perdition.pop3[1461]: Fatal Error reading authentication information from client 128.240.99.227:57653->128.240.99.221:995: Exiting child I've got the same configuration on the two server except the outgoing_server, and I'm using POP3S with self signed certificate. Can you help me please ? Thanks ! Aurélien.
