Email Server Port- How To Change/add Port For SMTP
Feb 19, 2008
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 anyone successfully using cPanel with smtp port 587 and have a working email account?
After deciding that Plesk wasn't for me due to the lack of reference material in this and other forums, I had my hosting company, ServInt, delete my old vps and install a new one with cPanel.
Everything went fine until I configured my email. Just like with Plesk, I cannot access the smtp server via Outlook. I can ping it successfully, but it either terminates the connection or doesn't recognize the correct user name and password. With Plesk, it was a simple matter of enabling the use of port 587.
Not so with cPanel, at least for me. Even though the Exim service is enabled and another instance is enabled on port 587, I still can't connect. Thought it might be CFS, which is new to me with this install, so made sure it was disabled. Opened up a ticket with ServInt and even their techs can't get it functioning, so _they've_ opened up a ticket with cPanel.
Hence the title of this post, I can't beleive that I'm the only one whose had this problem before because blocking port 587 has been done by BellSouth/AT&T for many years now.
Nothing like having your company email down for over 6 hours to keep you up at night.
I have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
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.
real 4m10.629s user 0m0.000s sys 0m0.002s
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)
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:
My app needs to be viewed using :8080 behind the domain. I want it be viewable without using adding any port behind. I've research on google and many said about edit the server.xml file but the problem is I can't located the file no mater what
I need changing the nginx port. I've followed various threads and have created a custom nginxDomainVirtualHost.php file at: /usr/local/psa/admin/conf/templates/custom/domain, while the website indeed moves to the port I have set, a second nginx thread starts at port 80 and takes over in it's place.
I need to put varnish at port 80 and cannot do so until all services relinquish control on port 80.

some here: [URL] .....
Turn's out to be able to change the nginx port to a non-standard port you need to edit 6 files
I have a Windows VPS with Plesk panel. Windows Server 2008 R2 with plesk panel version 11.5.30.
I tried to change the default plesk panel port (8443) to eg (1234) without any success.
The steps i followed are the following: 1) Firewall -> Inbound rule -> allow for port 1234 2) Firewall, Disable inbound rule for port 8443 3) IIS, PleskControlPanel, Bindings: changed binding from 8443 to 1234.
Now i type on browser: [URL] .... and while its loading after some seconds redirects me to [URL] ...
I have a reseller account that uses WHM/cPanel. So of course, SquirrelMail and Horde are already installed. I like to check my email at work, but unfortunatley, my employer blocks connections for say mydomain.com:2095.
Is there a way around this? I'm too much of a noob to try and install Horde again, bypassing the cPanel. I use Horde as the example because I need a good calendar and address book.
if i try to telnet to yahoo's mail server, i get this:
[root: #] telnet mx1.mail.yahoo.com 25 Trying 126.96.36.199... telnet: connect to address 188.8.131.52: Connection timed out Trying 184.108.40.206... telnet: connect to address 220.127.116.11: No route to host Trying 18.104.22.168... telnet: connect to address 22.214.171.124: No route to host Trying 126.96.36.199... telnet: connect to address 188.8.131.52: No route to host
but it works from one of my other hosted servers. this keeps mail building up in my queue as it cannot send mail out cause the connection times out.
I can telnet locally to send myself email. This is my own dedicated server.
i have no idea whats up - default policy is ACCEPT in the OUTPUT chain of iptables.
