IMAPS and SMTPS proxy server

Hi,
I come from Germany. We use Lotus Domino in our enterprise. After evaluating Lotus Ultralite we would like to use a imaps/smtps proxy server for email access.
Normaly we would use a Cisco ASA, but there seems to be a problem/incompatility with the iPhone Mail client.
The mail account can be set up on the iPhone and is succesfully verified. But when I try to access my mails I only get an "server not found". The debug log on the ASA shows that the imap server reports an error and quits. I can access my mails with other mail clients like Apple Mail on 10.5.
So I am looking for an alternative. Which proxy server (soft- or hardware) can you recommend?

Hello
I am making HTTPS calls from within my applet code and this works fine using the basic Java Plug-in support for HTTPS.
This means my code basically does:
URL url = new URL("https://myhost.com/servlet/Test");
URLConnection conn = url.openConnection();
etc..
We are using Java 1.4.2. I've read in the "How HTTPS Works in Java Plug-in" for 1.3, that the plugin uses the browsers API for making HTTPS connections. Is this still the case for 1.4?
My basic problem is that it all works fine if the browser is NOT configured to use a proxy server. If a proxy server is configured we get the following Exception in the client:
java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Request ( The data is invalid. )"
I have read that "Sun's Java Secure Socket Extension (JSSE) library allows you to access a secure Web server from behind a firewall via proxy tunnelling. However, JSSE expects the proxy's reply to the tunnelling request to begin with "HTTP 1.0"; otherwise, it throws an IOException" (http://www.javaworld.com/javatips/jw-javatip111_p.html)
The article talks about using the JSSE library but it seems to be assuming the client is an application not an applet.
How do I use JSSE from within an applet if all the proxy information I seem to need to set in the JSSE code is held by the browser?
Will JSSE support proxies returning responses beginning HTTP 1.1 in the future?
Any help on this would be greatly appreciated.
Many thanks

11 e-mail accounts from different providers are suddenly giving me errors saying they can't connect to IMAP and SMTP server?

I have 11 e-mail accounts that was working fine a minute ago, but now they all say that they can't connect to the IMAP and SMTP servers.
They all work fine on my iphone.
How should i troubleshoot this?
Thanks in advance.

Nevermind, restarted for the third or fourth time, and now it works...
Perhaps it was a time-issue.

Ovi Mail IMAP and SMTP servers constantly down

I'm reading my ovi.com emails with a Lumia smartphone and with Outlook. I constantly fail to connect to the IMAP and SMTP server and thereby do not get or cannot send emails. Webmail works fine, but especially sending emails from Outlook or from Lumia is currently impossible. Mails just get stuck to the outbox folder and both Outlook and phone keep asking for the password, as if my password was wrong.
This has happened randomly after the Yahoo transfer, but now it is happening on daily basis. I haven't been able to send emails from my Lumia in a week. The settings both in Outlook and in Lumia are correct, have checked several times. Usually when I leave my phone alone for a night, in the morning it has synced the inbox, but not the Outbox.
Anyone have similar problems?

Ok.. if you guys have a final configuration please share...
I spent all morning and this after over 30min chat with nokia care support... final answer? they told me to contact Yahoo!
In the meantime, I also contacted nokia through tweeter and they were like: .. but nokiamail has been deactivated! I found it strange because my last income email on my cel was on Aug13... and I can still access nokiamail through webpage (www.nokiamail.com) so it´s not dead.
I´m using my name on the site as ******@ovi.com (cool, right?) but I want to have access to it on my ipad and another cel...thx for any help!

HTTPS and a Proxy server?

Does the plugin-in still not work with HTTPS and a proxy server?
From plug-in docs -
"Java Plug-in supports http, ftp, gopher and SOCKS v4 protocols through the proxy server. Currently, Java Plug-in does not support https (SSL). "

ASA DMZ zone and Unix proxy server

Hi.
i have router which all nat translation done at here. i have a asa and core sw.
192.168.1930.0/24 subnet my user and some server are located at this subnet. this subnet created at core sw.
int vlan 393
ip address 192.168.193.1 255.255.255.0
core sw connected to asa inside interface.asa inside interface ip 172.30.30.1 and at core sw site this port access vlan 8 which is
int vlan 8
ip address 172.30.30.2
at core sw at i have a default route to asa.
ip route 0.0.0.0 0.0.0.0 172.30.30.1
and asa site
route inside 192.168.193.0 255.255.255.0 172.30.30.2
all of them are ok.
i think that is ok.
at asa i have dmz zone which ip address:
interface Ethernet0/1
description connect to CoreSW
nameif inside
security-level 100
ip address 172.30.30.1 255.255.255.0 standby 172.30.30.3
interface Ethernet0/2
description DMZ zone connect mail server
nameif DMZ
security-level 50
ip address 172.16.10.1 255.255.255.0 standby 172.16.10.2
my proxy server inside interface connected to asa dmz zone and ip address 172.16.10.254 and outside interface is connected asa outside site which mean that is same subnet of asa outside interface which is 10.0.0.254 and then 10.0.0.254 i do static nat at router. i have no problem at nat translation.
i want my 192.168.193.0 subnet pass througth from proxy when this subnet want to connet internet.
i wrote
static (inside,DMZ) 192.168.193.0 192.168.193.0 netmask 255.255.255.0
and access-list
access-list from_dmz_to_in extended permit ip host 172.16.10.254 any
access-group from_dmz_to_in in interface DMZ
at this time what is up?
the user can not access internet and what i do? i wrote proxy server inside ip and default port 3128 at user internet explorer properties.
internet explorerr--tools-properties-connection-lan settting and show there 172.16.10.254 and port 3128.
at this time my user connect internet when i wrote this. when i remove this they can not connect internet
but i do not want write anything at my user. how i solved this?
after that one problem occur.
when my server to do nslookup it can not work.
i thnik that it is true because we have only one port 3128 is open and my server need udp 53.so it can not work
how i solve this issue?
as you see my access-list all of is open and i do
static (inside,DMZ) 192.168.193.0 192.168.193.0 netmask 255.255.255.0
it is this wrong proxy connection???
musti change proxy server inside interface to other device or asa other interface?
thanks.

There is 2 way the proxy server can work, ie: either transparent or explicit proxy.
From your explaination, explicit proxy works just fine when you configure the proxy settings on your browser.
The reason why transparent proxy does not work is because:
1) When user browser connects to the Internet, the ASA default gateway is via the outside interface, that is why the Internet traffic is not being routed transparently towards your proxy server which is connected to the DMZ interface.
The static NAT statement configured on the ASA does not perform redirection. If you would like to transparently route the internet traffic towards the proxy server on DMZ, you would need to route the traffic towards the proxy server. With the current topology that you have, it is not achievable on the ASA. ASA does not support Policy Based Routing, nor it supports WCCP when the user and the proxy server is on different interfaces.
2) Also need to find out if the proxy server itself supports transparent proxy.
Otherwise, since explicit proxy works, why don't you just push the proxy settings to the browser via Active Directory Group Policy?

Safari 3.x (Leopard) and Web Proxy Server Problems:

I have a Squid proxy server running on Linux. Users web traffic is directed through it via WPAD server which hosts a simple PAC file. The PAC files is very clean and small. It basically points all external (Internet) web traffic to our Proxy server. All of our Windows, Linux and Tiger clients work fine. However, Leopard (Safari 3.x) doesn't work quite right. Here's what happens:
Mac user logs into a Leopard 10.5 Mac. User launches Safari and tries to go to an external (Internet) site. The WPAD server is contacted and the Mac User is prompted to authenticate to the Proxy server. This is totally normal behavior thus far. Then, however, every few minutes the Leopard Mac user will be prompted to authenticate again (sometimes 2 or 3 times in a row!). Firefox 2.0.x, when configured to use the WPAD/PAC server and Proxy server, works fine in Leopard. Only Safari 3 in Leopard is having the problem.
All the Macs (Tiger and Leopard) are configured to use the Proxy server via OS X's Network Pref Pane (using the "Automatic Proxy Configuaration"). Reminder: Tiger works fine (even with the Safari betas), but Leopard's doesnt not.
I have attached our PAC file inline below (some things edited for privacy):
// SIMR automatic configuration for Mozilla and friends
// $Id: wpad.dat,v 1.8 2005/12/14 20:18:23 dct Exp $
// Edit carefully, since many may be relying on this...
function FindProxyForURL(url, host) {
// Bypass the proxy for internal addresses
if (!url.match("http:")
|| url.match("http://127.0.")
|| url.match("http://10.")
|| url.match("http://192.168.")
|| isPlainHostName(host)
return "DIRECT";
// These are exceptions given in the IE config for Windows.
if (host == "www.ncbi.nlm.nih.gov"
|| host == "chabry.caltech.edu"
|| host == "flybase.bio.indiana.edu"
|| host == "www.fedex.com"
|| host == "domain.org"
return "DIRECT";
return "PROXY <proxy server>:8080";
}

I think I have a similar problem. I am a Mac connecting to an otherwise all PC school network.
A new location with all correct proxies has been set up. However, Safari always crashes on first attempt to negotiate its way through our server to the internet. Internet explorer gets through because in its preferences it is possible to include the name of the school domain as well as my user name and password.
We have been unable to find any way of including the domain name into Location in Network or into Safari.
However, once Internet Explorer has negotiated with the server I can launch Safari and it works as normal.
Safari/Network seems to lack this option of including a domain name that my PC server requires.
Make sense to anyone?
Worth mentioning that my copy of Internet Explorer (5.2) often crashes, but usually it has done its job by then. I quite like the concept of Internet Explorer sacrificing itself to clear a path for Safari.

HTTP tunneling and reverse proxy server

We're currently using Windows Media Services (WMS) to stream
video on our website. There is an option WMS to use the HTTP
protocol and to specify the port you'd like to use. This has
allowed us to stream video through our external firewall, through
our reverse proxy server, and through our internal firewall to our
media server. I've been trying for two days now to get Flash Media
Server (FMS) to do the same thing. For some reason the HTTP
tunneling (RTMPT) protocol doesn't appear to be acting like the
HTTP protocol that WMS is using. Anyone have some tips on this
configuration. I've scoured web resources and documentation as best
I could. Any help would be greatly appreciated.
Thanks.

To give a better picture, here's a more complete description of set up and goals
Static IP hits external interface of ASA. ASA has a static nat rule to forward it to my DMZ server.
DMZ server is running IIS 8. Here are what some of the sites look like.
jira.xxxxx.com -> 10.1.10.21 (ubuntu server) | port 80
email.xxxxx.com - > 10.1.10.16 (domain joined server 2012) port 80, 443
media.xxxxx.com -> 10.1.10.14 (domain joined server 2012) port 80, 443
other stuff like this -> 10.1.10.x port 80 or others
All of the A records for those domain names point to the static which routes to the ASA and then is NAT'd to the DMZ server.
What do I need to do in IIS to have those sites get directed to the proper internal locations?
Thanks!!

InPrivate Browsing and a Proxy Server

Is it possible to have IE8 InPrivate Browsing use a proxy server and not regular IE8 not using the proxy without changing the settings every time I use IPB?

Hi,
Thank for posting in Microsoft TechNet Forum.
Inprivate Browsing only affect following items:
Information
How it is affected by InPrivate Browsing
Cookies
Kept in memory so pages work correctly, but cleared when you close the browser.
Temporary Internet Files
Stored on disk so pages work correctly, but deleted when you close the browser.
Webpage history
This information is not stored.
Form data and passwords
This information is not stored.
Anti-phishing cache
Temporary information is encrypted and stored so pages work correctly.
Address bar and search AutoComplete
This information is not stored.
Automatic Crash Restore (ACR)
ACR can restore when a tab crashes in a session, but if the whole window crashes, data is deleted and the window cannot be restored.
Document Object Model (DOM) storage
The DOM storage is a kind of "super cookie" web developers can use to retain information. Like regular cookies, they are not kept after the window is closed.
Based on my know, we cannot use a proxy server separately for Inprivate Browsing.
Hope it helps.

Alex Zhao

AAD Connect Health and outbound proxy server

Fired up the Azure AD Connect Health preview on some AD FS 2012 R2 servers today. Installation went fine and the servers show up in the portal, but no data is flowing. Event log shows repeated exceptions trying to connect to:
https://policykeyservice.dc.ad.msft.net/clientregistrationmanager.svc/AgentUpdateCheck?tenant=<mytenantguidhere>&env=adfs&productname=Microsoft.Identity.Health.Agent¤tversion=1.0.15022.0
The machines are on private IP addresses but have a proxy server configured (netsh winhttp set proxy). I'm not seeing any requests hit the proxy log, so I'm guessing the initial install used my IE proxy settings, but the service is not using the system proxy
config as it should.
Seems like a bug. Am I doing something wrong?
Cheers.

How to enable logging of IMAP and SMTP connections in Mail

I have set up my own mail server and am able to send and receive mail. However, I would like to enable SSL security for connections from the client application to the mail server. I have created certificate authority, created a root certificate, and created an SSL certificate and key for the server. However, every time I connect, I get a warning message that the certificate is not valid - but the host names and domain names are correct in the certificate and match in the error message. It appears that there is some other problem with the certificate that is not reported in the dialog.
I would like to turn on logging in Mail.app to try to find out what is happening as the connection is made and TLS is enabled to find out why the certificate is being rejected. What options exist for logging SMTP and IMAP connections in mail? How can I find the logging options - should I look for strings in the binary or a resource file?

You cannot log only those changes but you can log *all* changes.
The messages 111008 and 111010 are the ones to look for (as described in this post).

Imap and smtp, squrrelmail strange things

last night i had a problem with one of the drives failing on my xserve and causing our raid 1 to degrade. i did a rebuit and after 30 - 40 mins it was done.
this morning i noticed two things: there was an error 22 on the squirrelmail when people tried to login and some cannot connect to imap message. i went in the conf.pl file and changed my imap settings from mail.mydomain.com to localhost. users were then able to login but not being able to send mail until i changed the smtp settings in the squirrelmail conf.pl file from mail.mydomain.com to localhost.
i have not done any changes form last night but stopping all services and turning them back on after rebuild was done.
on top of that computer using both retrospect and other backup software stopped emailing logs last night, which i found even stranger as retrospect uses smtp authentication, the other machine does not but is's ip is added to the allow list.
i am still trying to figure out what is going on. i was successfully able to send telnet and send mail from the machines mentioned and all other clients have no problem sending mail. i am not sure where else to look for the problem.
any help or suggestions are appreciated.
thanks

PowerBook G4 - 12" Mac OS X (10.4.8)

jeff,
originally i though is mail problem but thanks for pointing me in the dns direction. here is my setup.
i have xserve running mail, web, dns, open directory master windows PDC 192.168.0.4 . i have a second xserve running web, replica and windows backup domain controller and backup dns on 192.168.0.9
i have only made it recently (2 months ago) backup dns and some of the static ip machines still have on old secondary dns ip 192.168.0.2
so my retrospect backup server had 192.168.0.4 and 192.168.0.2 but in the retrospect event handler had mail.mydomain.com for smtp server. i just changed that to the ip of the mail server 192.168.0.4 and ran retrospect and got the email which means that i DO have dns issues. i have not changed anything on my dns settings so it really bugs me out (at least i do not remember changing anything
i think i am gonna turn the dns services off on the backup dns xserve and see if i will get the same results.
the command you ask me to enter did gave this output
192.168.0.4
192.168.0.2
i will change the secondary dns to the new secondary dns ip but that should not matter, should it?
my other server is sgi irix and did gibe same output. is the resolv.conf file the one i want to edit if i want to change my dns server settings of the client?
my dns server (xserve) also had the two old ips 192.168.0.4 and 192.168.0.2 but i changed that last to 192.168.0.9. do you think that would have mattered? it has been like this all along ...
should i be loking on the dns server config to see if anything strange?
thanks for your help.

Use Yahoo! Push IMAP and GMail Outgoing Server

Hi. I use GMail as my primary email account, but I really like the Yahoo push IMAP capability.
I have setup my gmail account to forward to my free yahoo account.
How can I setup my iPhone to check my yahoo account (with push imap) but when I send, to use the GMail SMTP server? I can't find the outgoing server setting when I setup the yahoo account on my phone.

Read the reply post carefully people.
There is no mention of a magical new Yahoo account shortcut.
The reply post states that the only short cut that exist is when you set up an e-mail account.
The big one with Yahoo on it, the one you all would have had to of used already.
In other words their is no magic way of doing what you want to do.
