Smtp service (qmail) stops responding on port 25: # time telnet localhost 25 Trying 127.0.0.1... quit quit Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. quit quit 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?
Plesk info: OS Red Hat Enterprise Linux Server 5.9 (Tikanga) Panel version 11.5.30 Update #50, last updated at May 18, 2015 05:21 PM The system is up-to-date; last checked at May 17, 2015 10:56 PM
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.
Using Plesk 12.0.18 and CentOS 6.6, I installed PHP 5.6 through the Plesk Updates menu. After that, the new version was not automatically selectable inside Plesk Panel. I added it using php_handler.However, when selecting PHP 5.6 for a website, I only get a 500 server error.
Trying to troubleshoot, I ran "/opt/plesk/php/5.6/bin/php-cgi -v", which also resulted in an error:Fatal Error Unable to allocate shared memory segment of 67108864 bytes: mmap: Cannot allocate memory (12)The same kind of error is logged in the error_log for the website I switched to 5.6.
The error also occurs when calling "php-cgi -v" directly in the command line.The same error occured when I tried the same thing with PHP 5.5.
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:
For some application-testing I installed PHP 5.5 and PHP 5.6 alongside the existing PHP 5.3 installation. To do that I used the web-interface of the Plesk-installer.
Installing the software went well, or at least didn't show any errors.
After installing I went back to the login-page to get back into the portal, but that didn't work.
I am using the right username and password and don't see any errors, I just keep getting the login-screen and no errors. Logging in through SSH is working as it should. Only access to Plesk on 8443 seems to be denied.
Server reboot didn't work, restarting Plesk-services didn't work...
How can I restore this so I can get back to work?
This Plesk-installation is on a CentOS 6 server on which I have full rights.
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?
Is there any way to give a reseller or customer access to the php custom settings box labeled "Additional configuration directives" on the website & domains -> php settings button that an admin can see and alter? We have attempted to give resellers the "Common PHP settings management" and "Setup of potentially insecure web scripting options that override provider's policy" options, but it still does not show up to a reseller.
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 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.
I have a server(godaddy) with plesk. It was all working well till 8 - 10 days ago. I didnt notice it one week later where I started receiving a lot of failed mail notices. Then on investigation, there were more then 50K spam mails in the mail queue and the mails that were supposed to be sent(registration, forgot password) were also held up in the queue. I found the source of the spam and fixed that.
Also I cleared the mail-queue. Now when I try to send out a test message, it still gets held up in the mail queue. But I can send a test mail to the same domain (firstname.lastname@example.org). All new user registration mails are also held up and this is greatly affecting the site.
Domains are simply not showing in the controlpanel. We can see the subscriptions but its empty under the button 'Domains'. Newly created sites as well as migrated sites do not show.
Before we created or migrated a site to the server we changed psa.conf HTTPD_VHOSTS_D /home/httpd/vhosts This is a legacy from our old servers and never has been a problem. I suppose this is not related, but just thought I should mention it.
The second problem with this server is that when we toggle the mailservice in 'Services management' the button reacts but does not change the state of qmail. It just keeps running. What can be wrong with this fresh installation?
