Click Exim Configuration Editor

Check the box next to:
“Send outgoing mail from the ip that matches the domain name in /etc/mailips (*: IP can be added to the file to change the main outgoing interface)”

Then edit the file /etc/mailips

from shell and add:

*: #ReplacewithnewIP#

service exim restart

2) Login to Shell

Access the Exim configuration file:
nano /etc/exim.conf

Locate remote_smtp

The default setup will look like:

remote_smtp:
driver = smtp
interface = ${if exists {/etc/mailips}{${lookup{$sender_address_domain}lsearch{/etc/mailips}{$value}{}}}{}}
helo_data = ${if exists {/etc/mailhelo}{${lookup{$sender_address_domain}lsearch{/etc/mailhelo}{$value}{$primary_hostname}}}{$primary_ho stname}}

Change to:

remote_smtp:
driver = smtp
interface = 12.14.12.14 # Change to your server IP address.

Save changes and exit.

Restart Exim

If there is an exim update when you upgrade your cPanel server you will need to re-enter the interface again.

The SMTP tweak will prevent users from bypassing the mail server to send mail (this is a common practice used by spammers). It will only allow the MTA (mail transport agent), mailman, and root to connect to remote SMTP servers.

Steps

1 To access the Server Setup Menu, click on Server Setup, on the main screen of your WebHost Manager interface. Then, click on Tweak Security.

2 Click on Configure in the SMTP Tweak section.

3 Click on the check box next to Allow connections to localhost on port 25 to allow users to connect to localhost on port 25.

4 Click on Enable to enable the SMTP tweak.

You can change the IP address that exim uses to send mail by changing the following in my exim.conf a follows:

remote_smtp:
driver = smtp

to:

remote_smtp:
driver = smtp
interface = 123.123.123.123

Resolution :

In WHM on Exim Configuration Editor, rewrite two routers, There is an edit box bellow “ROUTERS CONFIGURATION”, Box is before “lookuphost” router,
Put these lines to that box:

(7th box from top in exim configuration)

Quote:
mylookuphost:
driver = dnslookup
condition = “${perl{checkspam}}”
domains = ! +local_domains
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 : 64.94.110.0/24
headers_add = “${perl{mailtrapheaders}}”
transport = my_remote_smtp

myliteral:
driver = ipliteral
condition = “${perl{checkspam}}”
domains = ! +local_domains
headers_add = “${perl{mailtrapheaders}}”
transport = my_remote_smtp

Then move down to “TRANSPORTS CONFIGURATION”, On edit box there (just up the remote_smtp transporter)
put these lines:

(12th box from top in exim configuration)
Quote:
my_remote_smtp:
driver = smtp
interface = 72.29.75.244
This will be permanent and will not change by CPanel updates.

A system administrator may specify a size limit for original messages that will be attached to the NDR message. Messages that are larger the the limit specified will not be attached to the NDR message.

The following steps describe the procedure for configuring the limit:

Open the Registry Editor and point it to the following path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SMTPSVC\Queuing (if the Queuing key does not exist create it).

Create a REG_DWORD value called MaxDSNSize.

Enter the value of the limits in bytes.

Restart the SMTP service.

Ensuring SMTP Appears in the IIS Manager

Method 1)

1. First, click the Start button, then Run…
   
2. Now, type:

   regsvr32 %systemroot%\system32\inetsrv\smtpsnap.dll
   
   Alternatively, %systemroot% can be replaced with the drive Windows Server 2003 is installed on.

OR

Method 2)

By uninstalling and re-installing IIS, including the SMTP service, it has also proven to fix the problem. However, it is recommended you try method 1 first, before going to the trouble of uninstalling and reinstalling IIS completely.

The post Why Does SMTP Not Appear in the IIS Manager? appeared first on Hivelocity Hosting.

Error 553 is an email error that is usually caused by a lack of SMTP authentication. When trying to send an email through your local email client, if SMTP has not been authenticated, you might receive a message that looks like this:

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was ‘example@hivelocity.net’. Subject ‘test’, Account: ‘mail.hivelocity.net’, Server: ‘mail.hivelocity.net’, Protocol: SMTP, Server Response: ‘553 sorry, that domain isn’t allowed to be relayed thru this MTA (#5.7.1)’, Port: 25, Secure(SSL): No, Server Error: 553, Error Number: 0x800CCC79

Many mail servers, including our own mail servers, require SMTP authentication to properly relay emails. To fix this, you just need to enable it.

Start by opening the properties on your local email client. If you’re using Outlook, you can follow these steps to enable SMTP authentication:

1. From the “Tools” menu, select “Account Settings”
2. After selecting your email account from the list, click the “Change” button, and insert your server’s name into the form field marked “Outgoing mail server (SMTP)”.
3. Click on “More Settings…” and select the “Outgoing Server” tab on the new window that opens.
4. At the top of the Outgoing Server tab, check the box labelled “My outgoing server (SMTP) requires authentication” and make sure “Use same settings as my incoming mail server” is selected.
5. When you’re finished, click “OK” and close out of the Account Settings window.

Once you’re SMTP authentication is set, you should now be able to send emails without receiving the Error 553 message. If you need further instructions on setting up SMTP in Outlook, check the official Outlook 2016 Documentation.

SMTP, or Simple Mail Transfer Protocol, is the service that controls how your emails move across networks. By interacting with the Mail Transfer Agent (MTA), it ensures your communications reach their intended address.

Starting or Stopping SMTP Service in Windows

Starting or stopping your SMTP service on a computer running a Windows OS can be done in one of several ways.

Using the Windows Interface

To start or stop SMTP using the Windows interface, follow these steps:

1. Open Services. This can be done from the Start menu -> Control Panel -> Administrative Tools -> Services
2. In the details pane, right-click Simple Mail Transfer Protocol (SMTP)
3. From here, you will be able to select the appropriate service state, turning SMTP on or off as needed

Using the Command Line

To start or stop SMTP using the command line, follow these steps:

1. Open a Command Prompt. This can be done from the Start menu -> All Programs -> Accessories -> Command Prompt
2. Within the Command Prompt, enter the following command:
   
   net {start|stop} smtpsvc
   
   *Note: To view the complete syntax for this command, at a command prompt, type:
   
   net {start|stop} /?

Installation and Deployment

You should download the ansmtp installer and install it on your machine at first.
https://www.emailarchitect.net/webapp/download/ansmtp.exe

Install IIS SMTP Service

You can install IIS on Windows 2000/XP as follows: “Control Panel->Add/Remove Programs->Windows Components->Internet Information Service->SMTP Service“. For Windows NT user, you can install it from Option Pack 4.0 of Windows NT. After installed, you can start it from “Control Panel->Administrative Tools->Internet Information Service“.

ESMTP authentication/Trusted IP Addresses

The default setting of IIS Smtp service may cause failure in sending email (“Error with sending recipient”). Here are two solutions to the problem.
Enable ESMTP authentication of IIS SMTP Service

“Control Panel->Administrative Tools->Internet Information Service->Default SMTP Virtual Server->Properties->Access->Authentication. “. Check the BASIC Authentication.
“Control Panel->Administrative Tools->Internet Information Service->Default SMTP Virtual Server->Properties->Access->Relay “. Check the “Allow all computers which successfully authentication to relay …”

Trusted IP Addresses

If you don’t want to do ESMTP authentication, you can add the IP address of your computer to Relay IP Addresses List of IIS SMTP Service.
“Control Panel->Administrative Tools->Internet Information Service->Default SMTP Virtual Server->Properties->Access->Relay” Check “Only the list below” and add your computer IP address to this list. Any email sent from this IP address will be accepted by IIS SMTP Service even without user authentication.

Send Email by Pickup Patch/Mail Queuing

After installed IIS SMTP Service, there is a directory named “Pickup” (“C:\Inetpub\mailroot\Pickup“). IIS SMTP Service keeps on monitoring this folder, once an email is saved in this directory, IIS SMTP Service will queue this email and send it automatically in background.

How does IIS SMTP Service manage undeliverable emails? It saves those emails to specified folder (“C:\Inetpub\mailroot\Badmail“). If you want to receive those undeliverable emails, you can add your email address in “Control Panel->Administrative Tools->Control Panel->Administrative Tools->Internet Information Service->Default SMTP Virtual Server->Properties->Messages”

If an email couldn’t be sent to specified email address in first trial, IIS SMTP Service would move it to “Queue” folder and IIS SMTP Service would keep on retrying later until expired. You can set expiration timeout of IIS SMTP Service in “Control Panel->Administrative Tools->Control Panel->Administrative Tools->Internet Information Service->Default SMTP Virtual Server->Properties->Delivery”

1) Open a command/DOS prompt while connected to the internet.

2) Type in the following command and press ENTER:

telnet mail.the-domain-name.com 25 **REPLACE: the-domain-name.com with your actual domain**

If the above command errors out then your ISP is blocking port 25 and you must use their server to send.
