Sending Email Cpanel :: SMTP Command Timeout On Connection
Jun 3, 2008
i have this weird problem of emails not gettign delivered and i am hosting with theplanet. Every email is sitting on the queue and not delivered.
i checked with dnsreport and it says
Timed out [Last data sent: [Did not connect]]
and my exim_mainlog shows
R=dk_lookuphost defer (-1): host lookup did not complete
2008-06-03 04:49:59 SMTP command timeout on connection
i have restarted exim, checked firewall and still i am unable to fix my problem!
update:
i again checked with dnsreport and my nameservers are failing
NS FAIL NS A timeout occurred getting the NS records from your nameservers! None of your nameservers responded fast enough. They are probably down or unreachable. I can't continue since your nameservers aren't responding. If you have a Watchguard Firebox,
it's due to a bug in their DNS Proxy, which must be disabled (31 Jul 2006 UPDATE: several years after being informed of this, there is a rumor that there is a fix that allows the Watchguard DNS proxy to work).
I am using Plesk Panel 11.0.9 (latest updates applied) on CentOS 6.4. at Strato. Unfortunately I can not send email from outside of the server (thunderbird). As I am not familiar wwith mail server configuration at all I would expect that plesk panel does that for me (right?)
* I can send emails via web mail. * I can receive emails in thunderbird, but sending runs into a timeout. * The plesk firewall configuration does have a rule for smtp (but I don't see for which port), so I would expect it is not a firewall issue * I would like to send with some security (starttls and encrypted password), but sending does currently also not work with any combination of (non-)security setting.
My domain has been migrated from another provider, I added it myself via Plesk panel later. The only mail-related change I did without plesk panel was to copy the mailboxes from my old server to /var/qmail/mailnames. But this should not effect sending email...
actually i want to know is this sending this email by my smtp server?

I have Plesk 12 on CentOS 7. I have only MSMTP installed not Postfix or Qmail. No matter what settings I use in the external SMTP settings the mail is never sent and I cannot find any error logs.
I have tried gmail smtp, sendgrid smtp and another smtp server that I own.
This is not a firewall issue as far as I can tell since if I install postfix it just works. Also any Wordpress or Joomla installs that use SMTP settings with gmail or sendgrid work just fine.
Screenshot for information only. I used accurate usernames, passwords, etc.

Quick update. I tried the recommended CentOS 7 with the same result. Can installing Plesk 12 without a mail server and using the msmtp relay option actually works?Click to expand...
where I can't access my terminal because my connections keep getting timed out. Its been ok previously but for the last 2 days I could not connect because the connection timed out 9/10 times. No modifications were made during this time so whats the problem guys?
I have a problem with my VPS. Hosting company have migrated my vps to a new and better dedicated server and now on all my sites(and IP) I got connection timeout error. I have changed "Main IP" and resolvers in HyperVM 10 minutes ago and it's not working(or I have to wait to wait like for nameservers registration?). I can ping my IP and all services(lxadmin,lighttpd etc are started successfully and its not wotking, I still getting connection timeout error.
Currently having a problem with proftpd on my centos plesk 8.1 server.
During large uploads, lets say around 10 MB the FTP connection fails within 5 minutes or so saying:
"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond."
I have asked for help from my server provider but they have tried and are now unable to help.
I currently have the APF firewall in my server.
Has anyone experienced this?
Below is the APF config file that i currently have & the proftpd config files that i have, if anyone can help it would be really really appreciated

So I am unsure where it is getting the "300 seconds" from.
Even though the error states 300 seconds, this problem happens way before 300 seconds every time and has happened during the transfer of files (when the connection has been active and in use).
I've tried 3 different FTP clients and used the "Keep Alive" option in each and it has absolutely no effect.
I am unsure if APF is causing the problem, I can't see any problems in any of the server logs in relation to ftp.
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 just recently logged into my user email account "the one which was created by the name of the user of the account" and found it had 8000 emails but none are showing up in either horde or squirrelmail. How can i delete all these emails without deleting the other bla@domain.com emails? Is there a way just to clear a specific email account in cpanel or a command line way. I think if i just delete the mail folder it would kill all the emails of that account and I just want to 'reset' that one.
I migrated a client from a Windows server to Linux and everything is fine except that mail sent to this client (say, example1.com) from a particular domain (say, example2.com) simply disappears and does not reach at all. Mail sent to that other domain (example2.com) from my new client (example1.com) is delivered correctly.
Incidentally, that other domain (example2.com) from which the mail is sent is with the hosting provider who was earlier providing services for my newly acquired client. Should I suspect anything? Or, is there a way to figure out what's happening?
I have MailScanner running on my VPS, but it isn't configured to filter at RBL level, only at Exim level, so I don't think this is the issue.
