Plesk 12.x / Linux :: Secure Connection To Mailserver Won't Work
Feb 17, 2015
I'm using plesk with CentOS 6.6 and the postfix/courier mail services...I tried to connect an existing mail account with a mail program like thunderbird. But I'm not able to connect to it, except when I'm using "no connection security"...So I tried, if manually contacting the POP3s Port is working:
Code:
openssl s_client -ssl3 -host mail.domain.de -port 995
with the following result:
Code:
CONNECTED(00000003)
write:errno=104
---
no peer certificate available
---
No client certificate CA names sent
[code]....
the same results come for trying to connect to port 465 (ssmtp) and 993 (imaps)port 443 (https) seems to work fine..i already checked if the corresponding certificates exist (e.g. /usr/share/imapd.pem) and filled with the standard certificate informtaion given by plesk checking openssl on the server gives the following result:
Code:
# openssl version
OpenSSL 1.0.1e-fips 11 Feb 2013
is there anything I have missed to configure?

I have used the patch : [URL] .... to disable ssl v3.
After I applied the patch getting error below when i try to send email via horde webmail:
There was an error sending your message: Could not open secure TLS connection to the server.
Roundcube can send mails well but horde not. Otherwise since applied the parch i can't get mails from gmail and maybe other providers i don't know yet.

I've written a script to send property data to rightmove.co.uk as part of their new automated data feed. However they require a secure connection to their systems when posting the data. They have provided me with a .pem file which is a security certificate. I need to install this on my plesk server but where to start as most certificates require a private key and the actual certificate. The private key I have been provided is only an 8 charter string, like a password.

One of my customer has a imap account installed on a Ipad, Iphone, Mac... Server : Plesk 10.4.4 (Centos).
Alternately, the account connection doesn't work ("impossible to connect to imap.xxx.com...").
I've modify imap file with this :
MAXDAEMONS=80
MAXPERIP=40
And after "service courier-imap restart".
But there is always the problem...

We set up a Plesk 12 server for web hosting purposes only.
All mail-related services, exception from "smtp server" and "Plesk milter" are disabled or uninstalled.
For specific domains, we want to prevent the useage of the php mail function with "localhost" to avoid problems with outgoing spam by unsecured scripts. Instead, we want to force webmasters to use external smtp servers.
Is there any directive or setting on domain-level that we allow for this limitation?

I am currently with a smaller US-provider where I am running a dedicated gentoo server with a dozen domains (all small stuff, mostly sme/private websites) and 2 dozen email accounts.
The nice thing about the current provider is that he lets me run sub-accounts where the holders of those accounts have their own billing. I let them run a domain/website on my server since its no extra cost for them, but they pay for the domain and extra email space for example w/o me having to care for it. They basically offer a minimum package and add every single thing on top of it, which I like since I do not need any webpage builders, templates whatever else. I rather only pay what I take.
Basically I am happy except for the connection speed, specially for the email. I am in Asia and other people using this server from Europe, and the time it takes to connect, up/download data to the server and to download larger emails is simply out of the normal.
any recommendations there? I am currently paying 75 USD/Mo + domain names. I think this is also a bit on the high side given that the server hardware is a bit out of date by now.
I am looking at the minimum to relocate only the email hosting to some faster service, which would have to have a reasonable storage size (>= gmail) with POP/IMAP access and of course to use my own domain names.

I changed the Plesk mailserver from Courier to Dovecot. All went good, but after the Install i can not see new E-Mails in my Inbox. Even the Search does not Work.
I can change the Mailserver again and use Courier. This works and i can see my emails. But only with Courier.
Some details:
Inbox has 100 E-mails. After scrolling down to the first emails, i can even see the newest email. But i have to scroll down and load all E-Mails.
Changing "Sort by" from "Date" to "Unread" all emails appear, even the latest. But changing to "Date" the newest email is missing again. Only a Number on my Inbox button shows me there has to be a new email in there.
The Open Xchange Team can not find any errors, the open xchange log looks good.

We were using the mailserver on our linux install, but have since changed over to an ms exchange server. With that I removed the mailserver and installed MSMTP relay only mailserver (SMTP client) option.
I configured the External SMTP Server settings under Tools & Settings / Mail with a valid email address password host name and port of 587. When I save it says settings saved.
Since doing this I have been unable to use the email link option for share files in the file share portion of my domain. When I try to select a user from the list to send the email to or even type an external email all I get is the error "Unable to send email".
When I checked the maillog file in /usr/local/psa/var/log, I get this error "Jun 20 15:42:59 u16271698 msmtp: host=smtp.1and1.com tls=off auth=on user=to@email.ca from=psaadm recipients=to@email.ca errormsg='cannot use a secure authentication method' exitcode=EX_UNAVAILABLE"
Where I have proper emails configured where I placed "to@email.ca"
How can I get this working with the MSMTP relay only mailserver (SMTP client) option installed?

I'm not sure why but this happen when I try to use SSL on WHM.. it just say "Secure Connection Failed" [url]
Quote:
The certificate is not trusted because it is self signed.
The certificate is only valid for luna.ndx2.com
But when I try [url]it worked fine. My SSL cert is sign by Comodo CA Limited.
From my observation, it looks like my host shared SSL cert is interrupting with WHM.

I'm transitioning from a shared account to a VPS and am trying to run it as securely as practical.
I've been looking at ways of keeping administrative connections to the server secure. So far I've considered VPN technologies like L2TP/IPSec and RAS but they don't seem suitable for what I need.
I just want a simple encypted, tamper-proof, computer-to-server connection in a Windows Server environment.

I've been using a shared account for many years and I want to move to a VPS. I am trying to decide between managed and unmanaged.
How much time and effort does it takes to set up, harden, and maintain a VPS?
I'd be running LAMP and email, mainly. I want to put time into developing my sites, not fretting about the server.
I guess I'd learn a lot by managing my own VPS, but what are the chances of getting hacked before I learn enough?

An error occurred during a connection to site.com.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)
The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
I'm not sure on how to fix this. Running CPanel.
I can access WHM/CPanel fine on SSL from the main IP. Just not any of the sites or CPanel from the other IPs.

One failure cited by a recent PCI compliance report was that of the Plesk non-https login at port 8880. I believe we can resolve this by adding a firewall rule to block access to this port but wanted to check first if this will have any negative consequences elsewhere. Or is there a better way to achieve PCI compliance on this point?

I've had a problem to get a connection to my websites via https. My Plesk is version 12.0.18 an it runs on ubuntu 14.04 LTS. I have installed the certificate in that way: URL....

After auto-updates I cannot connect to all my sites in ftp with filezilla.
These are the errors:
Unable to accept TLS connection: received EOF that violates protocol
I have tried this: [URL] .... but with no success.
I have restored permissions with:
/usr/local/psa/bin/repair --restore-vhosts-permissions but also in this case it cannot work for me.
How is it possible?
Firewall is ok. All is ok. I have this issue after updates.

I noticed Plesk uses an unsecured connection for webmail: webmail.mydomain.com
Can this connection be secured or is that not possible?
(Isn't this a security risk?)

For a Magento shop I want assign a dedicated IP to a domain. When I choose this second IP in “Subscriptions” --> Change Hosting Settings” and then select this IP under “Tools and Settings --> IP Addresses” as dedicated (or shared too) for this domain, calling the domain results in the Webserver´s default Plesk Page.
The Shopsite is not shown, but was working well with the shared standard IP.
Calling the IP directly with the browser shows the start page of the shop in raw HTML ( no CSS ).
Choosing a link results in a “Not found” page.

I'm running Ubuntu LTS 14 with Plesk 12 installed and I registered an domain name under subcriber/customer on my Plesk panel and I created a mail which was already registered under that name in the old server from which I removed the domain completely. I have installed Roundcube and Horde from Plesk installer, and at the avalaible webmail services are shown: Atmail,Roundcube and Horde all activated and avalaible. I try to choose one of them for the email but none of them works. When I try to access the webmail from the address: URL....it shows me default Plesk page. From the address: URL.... it says not found. The same for Horde and Atmail.
Its very weird because the same webmails services are working correctly under my main webspace with other domain: URL....I've tried changing something to the default plesk page from the file manager and it works so the domains seems to be connected with the server properly.

I have multiple domains on a single IP address and many require SSL Certificates.
I have enabled SNI in /etc/psa/psa.conf so it now says "SNI_SUPPORT true" as it was originally set to False. Setting this to TRUE then enabled the SSL option in 'Websites & Domains'.
I then purchased and installed the SSL Cert and activated it in the domain settings. On a dedicated IP address, this would work.
When I checked the certificate. it was not using the assigned SSL cert, instead it was using the Servers default certificate (plesk) that is assigned to the shared IP address.
When I check, I get the error message: "[warn] RSA server certificate CommonName (CN) `plesk' does NOT match server name"
I then rebooted the server and it made no difference. I changed the domain to a spare dedicated IP address, and the SSL Cert was certified correctly (it used the correct SSL Cert). When I changed it back to the shared IP address, it reverted back to the shared IP address' SSL cert. So the new SSL Cert was being ignored.
For info: currently running 11.0.9 on Centos 5 and I'm testing this with latest IE, FF, Chrome so it accepts TLS Server Name Indication.

With the fresh created emailaccount and you click on the webmailicon, it loads the following url but the page does not exists: URL....Aren't there any instructions for using RoundCube with Plesk? After adding Roundcube as an component are there more steps involved to get Roundcube up and running with plesk?
