    Hi,I have already installed and tested a &quot;postfix&quot; server on CnetOS.The purpose of this server is to let people send out email without authentication. We limit the IP address of the sender who can use this server. ------------ the above tasks have been done already --------------Requirements for this project:Part One:Install and configure &quot;policyd&quot; to limit the number of emails can be send out per user IP per hour.Need to make sure &quot;policyd&quot; can do this job otherwise please suggest alternative solution. If you know better solution than policyd please suggest.Installation is straight forward. Instruction has been found here http://www.policyd.org/Need to test it before hand over to me.( Must finish in 72 hours after the login is given)Part Two:Currently emails send out of this server go to SPAM folder of gmail (I believe other email providers as well.) I have already setup reverse DNS for the IP.Need to solve this problem.******** IMPORTANT ******You need to let me know in general what you are going to do when you bid in order to prove you know how to do this project. We need someone can solve the problem straight away instead of using this project as study.

    I have ongoing work related to our previous project &quot;Rectification of mail server issue&quot;

  • $25 USD/hr Today

    I am looking for someone who is experienced with Plesk panel and IIS to fix a number of problems I am experiencing with my site.My site is hosted with Hetzner and as part of the hosting package, I have Windows 2008 R2 and Plesk panel v.11 installed. Over the weekend, I had a problem with RDP that I eventually resolved, but in the interim I tried the &quot;Updates and Upgrades&quot; function within Plesk panel which upgraded not only certain components but also Plesk panel to version 12.When I now login to Plesk panel, I get the following error message &quot;The file init.php is part of Plesk distribution. It cannot be run outside of Plesk environment.&quot; I am able to access certain functions relating to the server, but when I try to &quot;open in control panel&quot; a subscription relating to my site I get the same error.I have contacted my hosts to try to resolve the issue, but if they reinstall the panel, it would mean reinstalling the whole system and the existing data on the hard drive would be lost. I don&quot;t want to do this, so I am looking for someone who can provide and implement an alternative solution.There are a number of (presumably related) issues with my site that have occured at the same time as the Plesk issue, so I am also looking for someone who can fix the following:When my site address - tour-tips.com - is entered into a broswer address bar, a login page is displayed rather than the home page. However, if I enter the full address for the home page - tour-tips.com/index.htm - the page displays correctly.My subdomain - data.tour-tips.com - is displaying the following error: HTTP Error 500.19 - Internal Server Error. The requested page cannot be accessed because the related configuration data for the page is invalidI am looking for someone who can fix these issues quickly so I can restore my site to its full functionality. There will be scope for future work as well once thse issues are resolved.Thanks

    Hello, Please read the requirements before responding. Please do not waste our time.#1 - Must Be Fluid and Experienced with 1and1 control panel, dns settings and set up, 1and1 dedicated Linux server.#2 - Must be familiar with anti spam dns settingsThe job is to set up dns on 2 sites on my dedicated server. The dns has to be set up so it will pass everything in mxtoolbox.I want to use one of my custom name servers as the primary and the 1and1 name server as secondary. i have tried to do this myself and have failed and 1and1 is no help. I cannot find anything on the internet about doing this either. I can only find info on how to basically switch on the secondary but not how to set it up in Plesk so if you have never done this then please do not reply. Here is a little background on my server:It is a dedicated server running centos. Postfix is the mail server. there are a few domains on it and dedicated ip addresses. The reason I am switching name servers is to meet the strict anti spam standards because my sites email is getting blocked due to not meeting these standards. For someone that knows this stuff it is maybe a 20 minute job. it is just a matter of changing 2 domains. I just have not been successful at it.Thanks

    Hello,I have a Mysql database that&quot;s quite heavy for my site currently, and i would like it optimized with caching and whatelse is possible.

  • $140 USD 11 days ago

    I have 1 website and 2 servers. i like to do mysql replication (master - slave) Slave will receive changes. I also need someone to set up Rsync so that the file changes are sent via FTP once daily via Cron Job. Both servers use Cpanel/whm and both sites must be 100% identical at least once per day with the Mysql updates happening.I have a DNS fail over solution for the sites, so if site a is down, site b will become live. Lastly, I actually have about 10 websites I need this completed for. So I know that you&quot;ve read the entire listing. Please bid the price for the 1st website. Then please post the price for each additional website. Please also tell me if you will need whm access or can complete this using just account cpanel access for the hosting accounts.I already have copies of the website on the back-up server, so I just need the mysql master/slave and the Rsync set up via cron. I would also like to know if you done this before! No quick bids please. I need you to talk to me about your experience doing this.
