I have Qmail installed on my Centos box. There seems to be some problem with connection because when I run DNSreport from dnsstuff.com on it it shows me that it cannot connect to mailserver.
I tried telnet from local and this is what happened...
telnet mail.mydomain.com 25
Trying XXX.XXX.XXX.XXX...
Connected to mail.mydomain.com (XXX.XXX.XXX.XXX).
Escape character is '^]'.
then nothing happens for a while (about 30s)
and then I receive this greetings message:
220 [mydomain.com] ESMTP NO UCE/SPAM on this server ESMTP
How can I speed up this process? Are there any lookups possible or what?
We are seeing intermittent slow responses from SMTP on a RHEL6 server running Qmail on Plesk 11.5. The response is being measured from a remote Zabbix server.
The response time seems to be slow (>10s) for a period of 2-3 minutes and then returns to normal (<1s). All other services continue to be ok during the period of slowness.
The server_args line in /etc/xinetd.d/smtp_psa already contains "-Rt0" and all the DNS servers in /etc/resolv.conf are resolving properly.
From looking at the maillog file the server was receiving about 35 SMTP connections a minute at the time of the slowdown. We have the server configured to use 2 x RBL's.
I wonder if we are hitting a limit on the maximum amount of SMTP connections. The file /var/qmail/control/concurrencyincoming does not exist so, according to the Qmail manual, there shouldn't be a limit on the number of incoming SMTP connections.
I've been trying to get ahold of Awknet (www.awknet.com) Sales sector for about a week now and still no response :-( Does anyone have similar experience? Or maybe Awknet just didn't get my email? :<
I have a dedicated server that I am renting that appears to randomly respond very slowly for some reason (pings are between 90-4000ms with about 75% packet loss).
This has been happening lately (about once a week for the past 4 weeks) and I thought I had originally found the cause of the problem but it appears I haven't.
Originally, when this problem was happening we were getting an abnormally high about of traffic but a reboot always fixed the issue. I've checked every where I can think of but I cannot find anything out of the ordinary.
ight now we're averaging less than 2Mbps in traffic, the CPU load is less than 0.75, the memory usage is at 55% with no swap being used, Apache connections are normal, no active SSH, FTP, or mail connections, I've restarted all services which had no impact, I've checked the access and error logs but can't see anything out of the ordinary.
I have a ticket open with the data center but I'm trying to figure this out on my own to fix whatever is causing this so I can move my data over to a new server we just got setup over the weekend in a local data center.
Limestone's support is extremely slow. I just got a server with them to host VPSes, so I was inquiring about additional IPs in case I needed them.
Their first two responses were within 4-5 hours, which is bearable. However, yesterday, I actually needed to order more IPs and posted a new reply. I have yet to receive a reply after over 12 hours and my client has been left waiting to receive the additional IPs he ordered.
I haven't been with Limestone long, and I haven't had much other experience with their support, but I was unsure what else to do other than post this here and hopefully get a resolution.
I know their servers are unmanaged and pretty cheap, but I think they should still take the time to answer tickets in a decent amount of time.
Has anyone had similar experiences with Limestone?
I recently made a shift to FDC for one of my servers that I use for downloadable content.
I went for a $199 server with a 100mbps shared bandwidth port. Now, the only problem I seem to be having with it is that downloads appear to be, I would say recognized, very slowly by the server before they start, however, once the download starts I get a full speed. This usually happens during peak times.
I'm using about 10/15mbps on the server according to my cPanel statistics. I just wanted to ask here prior to contacting FDC on this, whether this slow server response time has something to do with the bandwidth port, or perhaps the server's RAM, CPU, etc? Given I'm using quite minimal bandwidth on the port, should I consider having them fix this or upgrade the server instead?
And if I had to upgrade, would I need to upgrade the port or the RAM, or both for this?
This is in regard to ongoing stress I've had over this server from DN...
Keep in mind this is a NEW server order; my first with this company.
I was assigned IPs that appear to be on multiple spam block lists. The "biggest" problems are mail being dumped to bulk by yahoo and dumped to bulk or completely black holed by hotmail. It was also blocked by comcast, mail.ru, and anyone who uses SORBS (those are the only ones I KNOW about so far). This helps reinforce the suspicion that bulk mail was being delivered from the IPs at some point.
I Contacted support at 9PM on the 13th and was referred to abuse. Only after complaining again on the 17th, was I told they requested removal from ONE of the blacklists and they would "look into" the others. I replied saying I wanted new IPs or I would request a refund and that I did not feel the service I recently purchased was actually delivered.
Now here is the part that is giving me the feeling this will not end well for me; I no longer see the abuse department ticket when I log into their ticket system.
What If I ordered the server to use as a mail server? Am I out of line for finding a new server unable to deliver mail to the hotmail/yahoo inbox unacceptable?
Telling my customers to wait and maybe someday their mail will be delivered to the major free mail services is not the kind of reputation I want to have. Its feels like I was sold a problem someone else created and am expected to wait an unspecified amount of time to see if it can be resolved. I do not feel its fair to be left hanging while waiting for white listing attempts on IPs I did not soil in the first place.
I have built a database driven site with PHP & MySQL. Pages download quicker on some connections than other (obviously), however this is not due to connection speed. The web host server seems to respond very slowly to my boss's network (which is on a proxy server). Could it be that this problem is related to the web host? i.e. could it be that the web host is unequipped to deal quickly with this type of network?
On my home connection (2Mbps), pages often download instantly, however occaisionally I have to wait 10-20 seconds to receive the page from the host.
Finally, could you recommend an excellent web host to use with our site? My boss wants to offer a professional service where server response is quick. We are based in the UK.
I have Configured Apache2.4.4 for forward Proxy and tested from my browser the response is very slow and even not coming complete Response for some requests.
I also Tested the same for Apache2.2 Forward Proxy it is very fast and good.
May I know what is the Problem in Apache 2.4
Is there any Issues in proxy modules (mod_proxy,mod_proxy_connect.so,mod_proxy_http.so) in Apache2.4
This is the same configuration i used for Apache2.2 and Apache2.4
i have a fedora core 4 server.. and i want to install a good Qmail email server to host some emails of diferent domains..
On searching i found that Qmail should be install with those associated programs/system for a better server :
Qmail itself EZmlm and EZmlm-idx Autoresponder Vpopmail VQadmin maildrop QmailAdmin Courier-imap/imaps with Courierpassd Squirrelmail web mail program ......
I've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.
I monitor port 80 connections and rarely see more than 10 at a time. That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.
But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache
80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?
I'd like to ask on how to fix the message below after I checked my domain server at intodns.com which is similar to previous free service dnsstuff.com
DNS servers responded
ERROR: One or more of your nameservers did not respond: The ones that did not responded are: 63.xxx.xxx.xxx
The IP shown is the second IP of the server in which I assigned to my ns22.domain.com. I'm not sure if this is the reason why some subdomain and even main domain on the server suddenly cannot be access on the internet when it was working already.
my website serving only a piece of the page, but getting a 'bad server response' in the Activity Window of Safari, and CSS and other errors in FireFox, but both browsers rendering only a portion of the page.
What happened? I hadn't made any changes to the site or server in a long time.
Also it seems to be on the server since others are experiencing the same thing.
anyone know of any company with fast response time? (5-30minute no matter what time of the day it is, and maybe even guaranteed in some way?)
i have 3 different server at 3 different provider for redundancy and backup purpose and on top of that have also try 3 other hosting company but seem like support is hit and miss depending on time sometime waiting 4-8+ hours for a response.
I'm using kayako live response and i have about 4 staff members using the win app right now only 2, and my WHM service status is saying that my system is using almost 100% RAM....
Any ideas on what's the average response time there?
Server is down for a whole day. Staff doesn't reply, called but signal is like a "busy" phone all the time. Not sure if this is my telephone operator issue or what.
i have ordered my First Dedicated server with BurstNET for the past 24 hours, and till now i did not received any Response or Confirmation. also they did not replay my emails.
We are thinking to get Level(3) into our mix in Seattle datacenter. We did some tests from the UK, and the result is: Level(3) network can give less response time (from 3-10ms less), but run through more hops (4-6 hops more)
So, question is
- for normal hosting, which way do you prefer? Less hops or less response time?
- for VoIP service, which way do you prefer? Less hops or less response time?
Recently my VPS was not accessable when browsing to sites hosted on it. I noticed it and so did members of a forum hosted on the VPS.
I did a traceroute:
11 27 ms 27 ms 27 ms i-9-0.sydp-core01.net.reach.com [202.84.221.89] 12 180 ms 180 ms 180 ms i-3-0.wil-core03.net.reach.com [202.84.140.29] 13 180 ms 180 ms 191 ms i-3-4.wil03.net.reach.com [202.84.251.162] 14 180 ms 181 ms 181 ms assign.net.reach.com [134.159.63.66] 15 854 ms 261 ms * t3-2.mpd01.lax01.atlas.cogentco.com [154.54.3.141] 16 192 ms 192 ms 193 ms t7-1.mpd02.sfo01.atlas.cogentco.com [154.54.6.30] 17 193 ms 192 ms 193 ms t4-1.mpd01.sjc05.atlas.cogentco.com [154.54.6.70] 18 * * * Request timed out. 19 * * * Request timed out. 20 * * * Request timed out. 21 * * * Request timed out. 22 * * * Request timed out. 23 * * * Request timed out.
Those tracert's were timing out just before (one hop) they got to 18 193 ms 193 ms 192 ms Managed_Solutions_Group.demarc.cogentco.com [ 19 193 ms 192 ms 196 ms vz07-ca.privatesystems.net [205.209.146.207]
The last one I assume is the node of my host and one hop before it gets to my vps.
So, if I received a response (almost an hour after submitting) from support that "I'm not seeing any issues with your VPS currently. From the trace route you have provided, it would appears that there is an issue along your ISPs connection. Please contact them for further assistance."...
Would you agree it's an ISP issue or network issue at the data center? I believe it's not an ISP issue and that I received an inaccurate and unacceptable response.
How can we know that how long it takes our server to respond, in terms of Microseconds. Is it take long time while processing an Ms Access database or SQL Server, Sending flash movies to client.
For example, I can accomplish a task while reading data from server database , also I can accomplish it using an image or flash movie.
Which way should be efficient for my visitors, I am using a paid hosting plan.
Also I have another question.
How could I know that a web hosting provider company's server is a fast machine than other company. I have options like "WebHost Company1" & "WebHost Company2"
I host the same website on both servers, while I request some page in a client machine, How could I measure the efficency & speed of the server, I am sure both servers will not send content to client with same speed.
due to any reasons, may be 1 server has more traffic, has slow hardware, has longer route.
Also which technology is faster, ASP, ASP.Net, PHP, coldfusion. Is there some way to measure these facts about a webserver.
In these cases, how could I choose best server. How to made decession about that.
I am using Cute FTP 7.0 Professional. The FTP server that I am trying to connect is firewall protected and hence I am using port method. But still I am facing problems in logging in. The following is the transcript of the command window:

I can receive emails from qmail but couldn't send out any... I checked my mail logs and found:
Nov 14 17:53:20 server relaylock: /var/qmail/bin/relaylock: mail from 11.22.333.444:37277 (server.domain.com) Nov 14 17:53:23 server qmail: 1163498003.114915 delivery 708: failure: 11.22.333.444_does_not_like_recipient./Remote_host_sai$
Nov 14 17:53:19 server qmail-queue[11421]: mail: all addreses are uncheckable - need to skip scanning (by deny mode)
11.22.333.444 is my server ip. Why Do I got this error and how to fix it?? Anyone help please greatly appreciate.
I recently upgraded my Qmail systems. Since Inter7 was the one who did it for me previously, I contracted them to do it. Two years ago I was very impressed, my load was a high 20s, after they finished it was in its low 4-5 with 4 CPU processors.
This time I asked for an upgrade for the Qmail in general and also its spam filters as I am getting more and more spams and the load is increasing. They stabilise the server loads, add tons of fantastic new layers of spamming protection, helped monitored and customised their scripts to my systems.
Real professionals and real knowledgeable people when it comes to Qmail. I had nothing but praises two years ago. Two years now, I have still nothing but praises.
