Plesk 11.x / Linux :: SMTP Service (qmail) Stops Responding On Port 25
May 19, 2015
Since 15.05.2015 smtp experiencing problems.
Smtp service (qmail) stops responding on port 25:
# time telnet localhost 25
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
Connection closed by foreign host.
After server restart or sometimes apache stop or ixnetd restart its responding for a some random time, and then again it stops to respond. Plesk panel show it as stopped but qmail itself running in memory, and does other its work, it just stops responding at port 25, or responds with a huge delay.
I've tried change it to postfix, reconfigured with mchk, repaired with repair.sh -r, disabled and uninstalled parallels antivirus, antispam, dnsbl, disabled firewall, disabled smtp lock. Checked apache, dns. Enabled submission port which works when 25 port doesnt, but i need working 25 port.
Nothing solves problem, its just stops responding after some random time. There is no errors on maillog.
I think this problem occured after recent plesk microupdate, because i didn't do anything to server configuration in last months.
This article says it might be dnsbl [URL] .... but it disabled(from plesk panel) on my server, maybe there is way to focefully kill any relation to dnsbl?

update: xinetd restart is definitely brings smtp alive, but it goes off after random period of time (5min ~ couple hours)
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 have 3 servers ServerA(Web, mail), ServerB(MySQL+Master replication), ServerC(Mysqlslave+web)
It happens that my website stops responding for few mins and then it comes back again automatically. I checked the server logs but I couldn't find any suspicious.
Also, while the website is not accessible when I try to connect internally from ServerC to ServerA or ServerB using SSH. It takes lots of time (approx more than 60 seconds) to connect. When website starts working SSH is also working fine.
This is very complicated for me. Can anyone let me know what should be the problem or how can I find root cause of this problem?
From there on its not working. The keyboard and mouse directly connected to it are working. Also all the menus, but we can set the network address, do firmware updates etc, only from the serial port connection (once the serial port is working).
I checked the hyperterminal settings (9600 baud, 8 bit, 1 stop bit, no parity, no flow control).
Is there anything that I might be missing?
Perhaps I have to use something like a crossed serial cable instead of a straight one ? Character set issues? Terminal type issues?
We have spent days in front of the machine and on the phone with Dell without really getting anywhere. Its our first 2161DS so I still want to believe that we must be missing something.
After enabling File Sharing in Plesk 12, the service appears to function correctly. If only a few files are uploaded, they are ok. However, after uploading a directory structure with a handful of MB, and subdirectories, File Sharing stops. It shows at the top of the screen:
"Internal error: The File Sharing service is temporarily unavailable because the site is down for maintenance."
it also says in the main window:
"Unable to load folders list."
Clicking on Upload Files, that dialog also shows "Unable to load folders list."
I have checked that the ownership of those files on the server is www-data:www-data , and that permissions are 755 for directories and 644 for files, because it seems like ownership and permissions could be an issue, however that doesn't fix it. Removing all the files in the share does fix it, however that's not useful if the files should be available for sharing.
After migrating our existing client base from legacy Plesk 9.x servers and Expand to PPA, clients phoned in with mail sending problems. These clients are using submission port 587 because their ISPs intercept port 25.
Existing client, Outlook error message:
"None of the authentication methods supported by this client are supported by your server"
Testing with Thunderbird, error message:
"An error occurred while sending mail. The mail server responded: 5.7.0 Must issue a STARTTLS command first. Please verify that your email address is correct in your Mail preferences and try again."
It seems a "fresh" PPA requires STARTTLS on e-mail clients. It is furthermore confirmed that Thunderbird detects the e-mail server settings as dependant on TLS.
The problem is that TLS doesn't seem to work properly by default.
In order to preserve our existing customer base, we follow: [URL] ....
Bottom line, in your /etc/postfix/master.cf, change the line that says "submission" from this:
Currently I am using Linux + cPAnel and using the port 25 for email sevrer. Currently we facing 1 problem is, some user's ISP is not support port. May I know how can I add additional port into server and allow users to send mail by different port?
I am using Qmail for most of my email accounts which is taking up a lot of my Singapore bandwidth which is extremely expensive. Anyway to configure such that POP goes to my Singapore servers, while I setup a pair of servers in USA for my SMTP needs?
I have a Server with Centos7 + Plesk 12 and in the service configuration say that the Bind service is not installed, from command line i have install named services and make a manual configuration the first domain, but when I return to the service page in plesk... the problem is the same, the Bind Service is not installed; then the problem is when i want create a new hosting i need to go to the ssh to make the DNS configuration...
Got following Problem: Unable to find service node for web service on domain with id = 0
After a Check from [URL] ....
I tried this: [URL] ....

Deleted a domain workspace in Parallels Plesk and now I am getting this error when signing into the panel:Looked at the logs and been trying multiple commands (including the bootstrapper repair etc.)I found the full error from the logs:
[13-Jun-2015 16:35:33 UTC] PleskDBException: Unable to find service node for web service on domain with id=6 file: /usr/local/psa/admin/plib/PhDomain.php line: 1404 code: 0 trace: #0 /usr/local/psa/admin/plib/Smb/Subscription/Domain.php(490): PhDomain->getWebHostingServiceNode()
After deleting a domain, we got the following error which rendered the panel useless.

I am a new user of Plesk 11.5.30 struggling to understand how qmail is configured.
I intend to install ezmlm to work with qmail but the installation guide assumes that the qmail installation is set up per LWQ (Life with qmail - see URL....
For example the following are quotes from LWQ:All of qmail's system configuration files, with the exception of the .qmail files in ~alias, reside in /var/qmail/control.A series of configuration files resides under /var/qmail/users.
The qmail sendmail, which is normally in /var/qmail/bin/sendmail, usually replaces .None of these directories exist. So where are all these configuration entities?
I have issue with qmail server. I want to update ssl certificate and for this i have replaced older servercert.pem with new servercert.pem file in /var / qmail/ control/. and restart service of qmail using qmailctl restart.But after updating this certificate my web browser still showing older certificate details.
Due to some circumstances out of my control, I've had to move from postfix to qmail. In postfix, I simply edited master.cf and added a new line to open it up on port 26 and 25 at the same time. In qmail it's not that easy. I followed the instructions at http://www.daniweb.com/forums/post256079-2.html and it worked, but it takes about 15 seconds for thunderbird send the mail (it sits there saying 'connected to mail.domain.com)
Is there a better way of opening qmail on 26 or forwarding requests for 26 to 25?
I'm using Plesk 11.5.50 CentOS 6.5 64bit with Qmail. I have installed a SSL certificate on mail server "mail.company.tld" and is running successfully with smtp/pop3/imap4 daemon. Every user agent uses "mail.company.tld" for smtp/pop3/imap4. The qmail name is "mail.company.tld" (file me). The server has about 300 domains and 1000 accounts.
Now we want to add a new SSL certificate, called "mail.newcompany.tld", and use it only for certain domains. I would like to know if is possible to use the new SSL "mail.newcompany.tld" for a specific mail domain without using the old SSL "mail.company.tld" that isn't expired yet. From Plesk Panel I haven't found a section for using the SSL for a specific mail domain.
