Webmail Proxy slow

Hi,
Webmail Prxy ims 5.2 on one machine to second ims52 webmail/mstore.
The initial login is very slow, once logged in speed is good.
any ideas?
thanks

Hi Jay,
I looked at the network device between the
etween the ldap and the webmail,
i found the below deny from my pix.
106015: Deny TCP (no connection) from Y.Y.Y.Y/9267 to
X.X.X.X/389 flags PSH ACK on interface dmz_A.
This message means that there was a connection
without traffic, and the pix drop this tcp
connection.
To avoid this problem the webmail must send keep
alive packet to the ldap.No, actually, you don't want MEM sending a keep-alive. What you do want to do is to set the ldaprefreshinterval to be less than your firewall's idle drop. You also need to set your LDAP server's idel timeout to be less than the firewall's idle drop.
Letting the firewall drop a connection is a Bad Thing, in that it simply disconnects both parties, without any kind of RESET or other notification. You will leak file descriptors on LDAP, and will cause hanging on the MEM due to this.
Start with LDAP idletimeout. Then set the ldap refresh interval on your MEM.
>
Another thing, i changed the position of my webmail
so there is no pix or other device only switch (the
same dmz). And i will monitor the problem tomorow.
Please I looked at the tuning of the ldap, there is
only a litle bit of parameters to tune, please have
you a book reference for monitoring ?
Regards.
Mourad.

  • Problem with multiple webmail proxy

    We need four different installations of messaging server for our webmail proxy needs. (With and without PAB and with and without folders management). Soon these webmail proxies will have to be redundant... 8 installations on 2 machines (4 each). I tried to use the mailallowedserviceaccess attribute to restrict the access to a specific webmail for a specific user. Let's say that [email protected] should access only the webmail webmailgt.commerciel.com (142.169.xx.94). I don't want this user to access the webmail webmailtq.commerciel.com (142.169.xx.96). I configured a proxy authentification on the mailhost that host the mailbox of this user on another machine (142.169.xx.72). When the user will use the webmail two auths will be made on the Ldap, one from the proxy and one from the deposit.
    The two installations of the webmail proxies are on the same machine (The interfaces 142.169.xx.94 and 142.169.xx.96 are configured on the machine that have the IP adress 142.169.xx.31)
    The value that I wanted to set at the mailallowedserviceaccess attribute was "-http:142.169.xx.96". That mean that user1 could use the webmail if the request is not coming from 142.169.xx.96. The problem is that it doesn't work because the first Bind works fine because the client acces the proxy from is PC, but the second Bind (the one on the store server) works too, because it is initiated from the 142.169.xx.31 machine. (Not the interface 142.169.xx.96). How can I restrict the access to a webmail proxy if many proxies are installed on the same server? I tried some other things with the console (in the HTTP Access and Proxy tabs) without success.

    I'm sorry for the confusion. I'll try to resume the situation.
    We are an ISP and we offer four classes of service of webmail to our customers depending on there domain name. With and without Corporate Adresse Book and with and without Folder management. To do this, we have installed four webmail proxies and customized these installations to respond to our needs.
    Let's say that a platinum user have acces to a Corporate adress book (with all the entries of the users in his domain name) and have the possibility to manage his folders. A gold user don't have access to his Corporate Adress Book but can manage his folders, etc.... The Platinum user use the url webmail.platinum.com, the gold user use the url webmail.gold.com, etc...
    Here is my problem. What can I do, to restrict the access to the webmail proxy level platinum to platinum users only. If a 'wood' user (without Corporate address book and without folders management)) log in at the url webmail.platinum.com, he will have the same templates that a platinum user. So he will access to the informations about the users in the same domain name and he will be able to create folders. (We don't want this!)
    What I tried, is to restrict the access using the mailallowedaerviceaccess. But, it doesn't work, because the address validation used the adress of the machine, not the one of the interface. I remind you that the four webmail proxies installation are on the same machine, on different interface.
    I hope that I clarified the situation. Sorry, for my poor english!

  • Slow response from Webmail Proxy on the first SSL connection

    Hi,
    I encounter a queer problem with Messenger Express 5.2 patch1, acting as a http proxy (Mesenger Express Multiplexor) for another Messaging 5.2P1.
    The first time a user tries to connect through HTTPS since a certain amount of time, it takes about one minute to get the webmail login page. And then it takes one more minute to have the user authenticated after it enters the credentials.
    The next connections are almost immediate.
    Has anyone already seen this problem ?
    The same server doesn't show this problem when connecting on port 80 without SSL.
    It looks like the encryption keys exchange negociation takes a very long time.
    Can this come from a compatibility problem between the client (Communicator 4.75, IE5 or IE6) and the server ?
    Are there recommandations regarding Internal Encryption modules and/or server certificates ?
    (Algorithms , key length...)
    Any answer would be appreciated.

    1. Basically, there's a problem on one of the servers which the ASC is hosted on.
    2. It's not at your end. Nothing needs to be or can be done on your devices to resolve it.
    3. No.

  • Border Manger as proxy: slow internet connection

    Very likely it's not configured correctly.
    Have a look at the following:
    1. See the document on the BM CD, documents/craig johnson directory.
    Check to see if you installed BM on the server correctly.
    2. See tip #1 at the URL below.
    3. See tip #23 at the URL below.
    4. See tip #63 at the URL below.

  • Corp Firewall/Proxy Slowness

    Hi LCCS Team,
    I am working with a client that has some restrictions in his corp. firewall and proxy servers. In essence, each LCCS request has to go through the proxy servers and that slows things
    done considerably. Also, only http (80) and https (443) is allowed to pass through. Is there a way to force my code to only use https from the moment that the connection is made
    to the LCCS servers? I don't want to use rtmp, etc. since it delays the connection considerably due Flash trying to connect without success before it defaults to https.
    Thanks,
    Michael

    From what I've read, although I've never had to use it, you can tell the JVM to use a proxy by using the -D parameter and passing values when you run you're program e.g for an web/http proxy you'd do something like .
    java -Dhttp.proxySet=true -Dhttp.proxyHost=192.168.1.100 -Dhttp.proxyPort=8888 myjavaprogram
    You can also save these settings in a properties file and read them from there apparently. As for being behind/confronted by a firewall - don't thing there's much you can do about that if it isn't going to let you through.

  • WebMail proxy in iMS5.2

    I sucessfully installed iMS5.2 on a mailstore (POP, IMAP, SMTP, HTTP)
    On the mail relay, I installed a MTA, a PopProxy, a ImapProxy. But I couldn't find the webproxy installation procedure.

    When you installed the MTA the installation asks you
    what port you want your Webmail client to listen on -
    this is your Messenger Express client.
    To start this, make sure that when you start the MTA
    you either start ALL services, or specify the following
    ./start-msg store http
    Also, you MUST have the following parameter set or your
    proxy wont work.
    ./configutil -o local.service.http.proxy -v 1
    We have it working just fine with these minor changes.
    For more information, search on Messenger Express.

  • Webmail too slow

    Hi,
    Few days ago, I've noted that SquirrelMail is too slow ... When a user log in to the system, the system late too time in webmail.php script. From login.php to redirect.php is faster than redirect.php to webmail.php.
    The server can late about 1 minute to open the messages of a user via webmail!!!!
    What can I do? ... I've restart the server several time ...
    Thanks

    Hi,
    *you said:*
    *"Without knowing the number of processors you have, this is meaningless.*
    *Have a look at actual CPU usage while trying to login via webmail."*
    I have 2x2.8 Quad-Core Intel Xeon.
    How can I do the CPU usage while a user tries to login via webmail?
    *You said:*
    *"Reconstructing the mail database is a local process while IMAP is shut down. The physical location of the server does not matter."*
    Yes, I know, but maybe could have a network problem in the new datacenter ... For example, traceroutes to my xerves late so much:
    1 192.168.2.1 (192.168.2.1) 2.301 ms 0.875 ms 0.826 ms
    2
    3
    4
    10 * * *
    13 myserverDOMAIN (myserverIP) 10.378 ms 10.776 ms 21.508 ms..
    *You said:*
    *"What does matter is the amount of users and in particular the amount of mail messages which by nature of the IMAP service increase constantly."*
    In the old Datacenter, I have 29.000 Users and I don't have problem about slowing in webmail service.
    I don't know if it's a problem in the network traffic in the new datacenter or a local problem because reconstructs work very very very slow.
    Thanks for ur responses pterobyte .

  • BT Yahoo webmail so slow?

    It takes minutes to make a change! Is this the same problem Sky are having with their changeover to Yahoo mail?

    welcome to the BT community forum where customers help customers and only BT employees are the forum mods
    in order for the forum members to help please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run  btspeedtester  (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).
    are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
    Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

  • How do I set up a proxy server for webmail services to assist in migrating from NMS 4.15p6 on NT to iMS 5.1 on HP-UX.

    I want to have minimal if no downtime at all when moving the message store. iPlanet support hinted at an "unsupported" proxy server solution, and would give no further information. I am running the MMP with 5.1 and that supports IMAP and POP migration, but I need support for webmail services as well to complete the migration from NT to UNIX with minimal distruption of thousands of users. I am using the MoveUser utility to move the message store in hopes that will clear up some store corruption we have been seeing.

    To get this in a 'supported' fashion you might want to wait until the iMS 5.2 release. iPlanet has said this release would include a webmail proxy/mmp server to do exactly what you desire.
    A proxy server would not be a solution to your problem as it would have to have access and knowledge to the users mailhost attribute to determine to which host to route the webmail connection. The webmail proxy/mmp will have this functionality.
    You might want to contact your iPlanet rep about this product and maybe you could get a copy of it as part of a beta program. I know iPlanet is always looking for oppourtunities for feedback like this.

  • Slow webmail or php

    Hi All,
    I've been struggeling with a real slow (squirrelmail) webmail for months now never finding a solution to my problem. It seemed that it wasn't only the webmail getting slow, but also every php based application that was running on the server. When the server was restarted the problem seemed gone but only for a couple of hours. http eated up about 100% of the cpu when php-based url's were requested.
    The solution lies in a configure option in php. Php needs to be recompiled (while you're doing that you can also get the newest version, 4.4.4 in my case) i'm using the following options:
    './configure' '--prefix=/usr' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--disable-dependency-tracking' '--with-apxs' '--with-ldap=/usr' '--with-kerberos=/usr' '--enable-cli' '--with-zlib-dir=/usr' '--enable-trans-sid' '--with-xml' '--enable-exif' '--enable-ftp' '--enable-mbstring' '--enable-mbregex' '--enable-dbx' '--enable-sockets' '--with-iodbc=/usr' '--with-curl=/usr' '--with-config-file-path=/etc' '--sysconfdir=/private/etc' '--with-mysql=/usr' '--with-mysql-sock=/var/mysql/mysql.sock' '--enable-experimental-zts'
    The 'experimental-zts' options solves the slowlyness problem.
    Best regards,
    Eelco

  • Configuring mail between two Apples?L

    I have two apple computers, a desktop and a MacBook Air for travelling. I want to configure mail so that both have full functionality but to have the desktop as the "master". Therefore, any messages sent from the Air should appear in the Desktop "sent" box, and anything deleted from the Air should not be deleted from the desktop. Any ideas?

    Welcome to Apple Discussions
    No can do...
    You can not check the remove a copy from the sever after recieving message on MBA Accounts: Advanced tab, so that all messages are downloaded to the Desktop (check that box on the Desktop) for incoming messages, but, there's no way to get the out messages from the MBA (or a phone or any other device) over to the Desktop sent or out box.
    Webmail (browser based) would allow you one place to keep/see all your messages - but generally I find Webmail much slower and more cumbersome to use than a traditioinal e-mail client.

  • Messenger express(iMS 5.2) through firewall using apache Proxypass and ProxyPassReverse

    I am trying to get a reverse proxy setup to server my internal email to the intranet. I have this code in my http.conf:
    <VirtualHost dmz.server.com>
    ServerName email.internal.com
    ProxyRequests on
    ProxyPass /webmail/ http://email.internal.com:180/
    ProxyPassReverse /webmail/ http://email.internal.com:180/
    ProxyVia on
    </VirtualHost>
    when I enter http://dmz.server.com/webmail/ I get my login screen. I enter my id and password and click continue, the browser gives me url not found.
    This url is now in the browser:
    http://dmz.server.com/en/mail.html?sid=sfdefrafefwe&lang=en&cert=false
    I can edit the url in the browser to add webmail as in:
    http://dmz.server.com/webmail/en/mail.html?sid=sfdefrafefwe&lang=en&cert=false
    and the browser will then display my email folders.
    Am I missing something here? How can I get the correct url to be returned with webmail in it?
    How do others handle serving internal email to the internet? I also have iWS6.0, which i have not tried.
    Any suggestions would be appreciated!

    Why not use the MEM of 5.2? The MEM is a webmail proxy that allows you to have users all use say webmail.domain.com while you have multiple mail stores.
    If you want to contine using the method you're testing now then you need to not use http://hostname/webmail/.
    Since you've set this up as a Virtual Host then you should be able to set the ProxyPassReverse to
    ProxyPassReverse / http://email.internal.com:180/
    If you've got something important at / then either move that or use another virtual host and use / under it.

  • IMS 5.2: smtp server hangs

    Running on Solaris 8, the smtp server seems to hang every few days, with the result that mail for my site ends up being hung up for hours until we restart the process.
    Is this a known bug?! Any way to fix it?
    It doesn't make iMS a very attractive solution for an enterprise that relies heavily on email.

    Hello,
    I know that there has been a number of fixes on solaris as well as NT since Feb dist. Here is what I have of the bugfixes, there may have been more since this hotfix. If you have a license you should be able to ask sun support for the latest hotfix.
