cPanel update email bug (loopback test fail even) - SMTP+Imap responsive
Something happened overnight on one of my cpanel servers, which I am still waiting on cpanel to get back to me for.
Here's the deal:
cPanel server was functioning well for the past 4 months, then yesterday all of a sudden no emails get received by users.....
Courier-imap pop3d fail to deliver message to a POP client on first attempt. On the second attempt its able to download the messages and no problems. Not sure what could be causing that problem. Are there any tools that are used with courier-imap mailboxes for fixing corrupted mailboxes?

I have a problem with spoofing spammers.. my queue is plenty of non-delivered emails from externals SMTP, sended to NON-existents address on my server...
The question is the destination domain (mydomain.com b.example) has already its ":fail: No Such User Here" alias.
SMF records applied, but not the most external SMTP servers checks them nowadays...
Using :fail: the email is never accepted into the server. During the initial SMTP negotiation when the senders SMTP server connects to your SMTP server, the sending SMTP server issues a RCPT command notifying your server which email address the email to follow is intended for. Your server then checks whether the recipient email actually exists on your server (a POP3 account, an alias or a catchall alias) and if it does not, it issues an SMTP DENY which terminates the attempt to deliver the email.
Well, in my case it justs receives message and then frozen it!

just need a simple smtp test......
I run a DNSReport.com test for my domain name and it failed on "Mail" section with this error message:
HTML Code:
ERROR: I could not complete a connection to any of your mailservers!
my-domain.com: Timed out [Last data sent: RCPT TO: ]
If this is a timeout problem, note that the DNS report only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.
also on DNSReport.com mail test, got this error message:
HTML Code:
my-domain.com. - xxx.xxx.xxx.xxx [Could not connect: Could not receive data: Operation timed out.]
[Note that if your mailserver takes over 30 seconds to respond, our test will timeout, even though real mailservers will wait longer] what makes my server failed on this test?
I've setup a domain for mail only (no hosting), with the DNS records hosted on AWS Route 53. Telnet fails for this domain.
View 2 Replies View RelatedI have a question getting the setup of my DNS and email server working correctly.
In my mailserver, lets say I set the SMTP server to mail.BLUE.com. Through my DNS, I set an MX record for mail.BLUE.com and I set an A record for mail.BLUE.com to 1.1.1.1.
I create different domains on my mail server and give each an IP address. BLUE.com is 1.1.1.1. RED.com is 2.2.2.2. GREEN.com is 3.3.3.3.
Each domain is setup in my DNS as a forward lookup zone. Each domain has an MX record (mail.domain_name.com) and a A record (pointing mail.domain_name.com to it's IP address). There are other records of course... but they're not important for my question.
When I want to check or send mail from BLUE.com I use mail.BLUE.com. When I want to check or send mail from RED.com I use mail.RED.com. I do this for all my email accounts.
But, when I check dnsstuff.com on any domain besides BLUE.com, it tells me the following:
****************************
mail.RED.com claims to be host mail.BLUE.com [but that host is at 1.1.1.1 (may be cached), not 2.2.2.2].
****************************
Now... this can send and receive mail just fine... but I think this may cause issues when it comes to SPAM settings (some servers may consider our mail SPAM because we're "pretending" to be a different mail server).
So... here's my question... what's the best way to set everything up to run multiple sites and email accounts on one server?
How can I use 1 SMTP mail server (BLUE.com) and get my other domains to pass the dnsstuff.com test?
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.
any 'easy' smtp / pop / imap package or installer w/o having to read up on exim etc.?
I want an email server quickly, w/o having to become an expert...
I'd go w/ a hosted service, but I open allot of pop3 connections... (program I use downloads one email, closes connection, reopens... repeat)...
There's lots of cookbooks out there, but they require quite a bit more time commitment (and configurability) than I want / need.
Is there any dumbified installs available? I tried with webmin, but even that wants me to manually configure a postfix / imap server bridge.=
cPanel/WHM updated to version 11 Release a couple of days ago but I am not getting the UPCP email anymore, I have not changed anything on the VPS
Verify the existence of email senders. if so it is not ticked and I have also checked the mail queue and it is empty
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).
We have a few users that use SSL email and we decided to purchase a cheap single-root SSL cert over at namecheap for the host name so that it would end the "self-signed cert" whining.
We got the cert installed and it works great for WHM/cPanel and also works for SSL over IMAP and POP3, but the very first email anyone sends (SMTP) per day gives this warning (Outlook Express):
The server you are connected to is using a security certificate that could not be verified.
A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.
It seems obvious that the cert used by the SMTP system is not the new one we installed.
We used WHM's SSL/TLS -> Change Server Certificates link to install the cert.
We then made sure that:
/usr/share/ssl/certs/host.domain.com.crt
/usr/share/ssl/private/host.domain.com.key
/etc/exim.crt
/etc/exim.key
...all contained the current cert or key as appropriate.
Just for grins, we even made sure:
/usr/local/cpanel/etc/cpanel.pem
...had the correct pair.
We restarted all the mail services and even restarted the whole server. (I know...Windows reaction...bad tech.)
Does anyone know of a stealth location where the SSL cert for SMTP should be updated?

I want to cap users on outbound emails ....
Example: User A sends an email to 100 people (using To,cc and bcc) . However the server needs to stop sending that message and cap a limit of 5 recipients per email
I know I have seen a command line you can use which will activate :fail: in all the accounts on the server simultaneously so that you don't have to do each account separately, but I can't find that command.
Does anyone here know what that command is? I'm assuming it would involve /etc/valiases/?
I am programming a bulk email sending for a client. I need a hosting company who can allow me to use Require 'Mail.php' to send about 5000 emails continuosly without fail.
View 7 Replies View RelatedMy problem is like this, I try to transfer an account from my old host to new host. This is how I do, I download all the file using ftp and upload all the file to new host.
Then I found that, website ok, email account created, database ok.. but IMAP email is gone ...
Is anyone else out there hosting IMAP email with MediaTemple? I am trying to transfer IMAP accounts to MediaTemple after switching from an email only provider, MailSnare. I use Mac Mail as my email client and am having trouble getting my accounts set up properly. It seems to have to do with my path to IMAP.
I've tried everything including:
(blank)
/mail
mail/
mail
INBOX.
INBOX
Different techs at mediatemple told me to use /mail and INBOX. but neither work properly. For the most part, I have been able to see my mail, but not my folders, or not all of my folders, or I've gotten repeated warnings that IMAP command "SELECT" failed. In one of my accounts now I can't see the mail at all, but the account is telling me there is 1 unread message. My problem seems to have been complicated by all the messing around with the preferences trying to fix things. If it makes any difference, the email address for the account is the same as it was with my previous host. I wonder if that's causing a problem when trying to access the mail in Library/Mail?
What is everyone using for IMAP-P ?
View 0 Replies View RelatedI have a couple questions maybe some of you can help me with -
I have a dedicated server and many hosted customers, I want to setup SSL for IMAP email and their cpanels.
Instead of purchasing individual SSL certificates for each domain. I was thinking to just use my hostanme (eg host.myhostname.net) and direct them to that as I have seen the option in WHM.
My question is can I use an SSL cert for email that will act as a "fleetwide" SSL cert?
For example instead of using mail.theirdomain.com could I just use mail.myhostname.com and would it give them SSL without warnings? Of course they would set their email client to mail.myhostname.com..
Is it safe or recommend to use your hostname? I read somewhere to never use your hostname as a domain.. so not sure.
I would like to find a host with good quality & uptime that has large disk capacity for hosting IMAP email, about 10 to 20 gigs in size per domain.
I know of places like Bluehost and powweb but I'm not crazy about the 'overselling' issues related to them....
Any Ideas?

emails handled with imap after a few minutes are automatically marked as read!
I'm looking for quality hosting at the right price for a small business. I have been searching these forums, but just got no conclusion, and would appreciate any advice concerning 'features' and 'providers' that I shall look at or avoid.
My needs are:
- very reliable email, with IMAP, good spam filtering, and ability to handle Challenge Response type system;
- rSync and storage of company internal documents (intranet like);
- host a small static website of a small b2b company, with little but valuable traffic;
- handle multiple (non limited) addon domains;
- for the near future: mysql, Ruby on Rails (need to explore it), Python and a good Content Management System;
- good stats tracking tools -- ability to log a list of sessions would be great;
- control panel doesn't matter, ssh would be nice;
- datacenter location doesn't matter too much, connectivity, reliability, and uptime do;
- 5~10GB storage mainly email and internal docs;
- 1GB traffic mainly email;
- preferably with a community forum - I trust more on those who have it, and have nothing to hide;
Do you think I can get something reliable for under $10/month or $100/year ?
I have found these options:
GeekStorage - looks great, LiteSpeed is appealing, people behind it look experienced, I was almost signing for it when I was caught by several issues with long downtimes (over 24h) during the last 2 months;
MediaLayer - also offers LiteSpeed, good comments by many on here, but no listed prices - why hidding the prices? are they trying to screw our bucks? that doesn't sound good to me;
HostGator and LunarPages - very popular, but they don't seem the thing for me, maybe for those with blogs, forums, or GoogleAds oriented websites, I get puzzled how can they offer 600GB for $7.95/month !?
FusedNetwork, Steadfast, DowntownHost and many others - seem to be oriented to lower storage and higher traffic, the opposite of my case.
I know I can get dedicated storage services, but a large amount of my storage need is for email which need to be synchronized through IMAP. BTW, can IMAP be used to synchronize files beyond messages?
I have a client with a dedicated server running. Spec below.
The problem I am having is with incoming email. When I set up a new email account it can take about 10 attempts to log on to the incoming mail server. Once it has connected it will be ok for a short while then I will get a connection error and no emails will come through.
This is happening across all platforms, PC / MAC / iPhone and iPad.
I am a web designer with limited knowledge of the setting up of the server and was looking to set up email server within plesk.
