To identify whether or not your inability to deliver emails to your Gmail users is related to blocking issues, follow the steps below:. This process can be time consuming, especially if you are sending large volumes of emails. Thus, we recommend a much easier way to diagnose the problem — use the GlockApps Bounce Monitor to track bounces and get bounce analytics with SMTP errors.

Why Google Can Block You

If you correct the issue, then these blocks can be resolved automatically. On the other hand, if the issue is left unaddressed, Google may decide to block your email entirely. You will have to take some action before Gmail removes your server IP address from their blacklist. In case you send legitimate bulk emails and get bounces with the error code, then you need to go through the Google's Bulk Sender Guidelines and then complete the Bulk Sender Contact Form.

Also, it is recommended that you sign up for a Google postmaster account and check your sending domain reputation with Google. And it is important that you stick to the best email marketing practices to make sure the IP does not get blacklisted in the first place. Scan your emails through all the major spam filters before you send. Get actionable tips for improving your delivery rate for every email you send. Improve your overall email performance by ensuring more emails are being delivered. Usually the username and password used for mail forwarding are the same as the username and password used for ATRN receiving.

This method allows the system to deliver a message either directly to the recipient computer or to a relay host that is "very close" to the recipient computer. Recipients can read your messages almost immediately, and your messaging system does not rely on any "forwarding mail server" performance.

When the Server queue contains several messages to be directed to the same domain, the SMTP module opens a connection to that domain mail server and sends messages one by one. If the established connection is slow and there is a large message in the Queue, other messages would wait too long before being delivered.

You may want to allow the SMTP module to open additional connections to the same mail server and send other messages in parallel. When outgoing activity is allowed, the SMTP module tries to send all submitted messages accumulated in its queue.

If an attempt to deliver a message fails, the SMTP module can delay delivery of that message, or it can delay delivery of the entire host queue if a connection with the host could not be established or an established connection was broken, etc. This feature is especially useful if your company has several offices and E-mail traffic between the offices is sent via the public Internet.

You should simply list the domain names that should receive mail from your server via secure connections:.

Thank You. You have successfully logged in.

Then the SMTP module uses this command to initiate a secure connection with that relay. The remote relay Certificate subject must contain the cn Common Name field that matches either the domain name of the remote site, or the name of this relay. This can often cause a problem, since the domain company. To solve this problem, you should explicitly route all traffic to the company. If the domain is listed in the Send Secure To Domains list, and the receiving server does not support the STARTTLS command, or the remote server certificate cannot be validated, or the remote server certificate Subject does not match the domain or domain relay name, all messages to that domain are rejected , ensuring that no message is sent via a potentially insecure link.

The SMTP protocol is used to receive messages from the Internet and from the client mailer applications. The option value specifies for which sending mailer IP addresses this feature should be used. Note: this option checks for the "fixed" Client IP Addresses only - it does not pay attention to the "temp-client" addresses added with the Process as a Client Address feature. Note: use this option carefully.

Some users may use different mail relays to submit their messages with their CommuniGate Pro Account names as the message Return-Paths. If this option is enabled and those messages are directed to your Server, they will be rejected, because mail relay servers are not able to authenticate the senders on your Server. Make sure that your server does advertise it see above. If E-mail to the Account can not be delivered immediately Account is over quota, etc. When your Server is off-line, all messages directed to your domain s are sent to that back-up mail server.

The back-up mail server tries to deliver collected messages to your server.

Usually, the retry period is 30 minutes, so your system should stay on-line for at least that period of time in order to receive messages from the back-up server. When the back-up server receives that command, it immediately starts to send the collected messages to your Server. Note: the name of the back-up server should be the name of the real computer as specified in an A-type DNS record , not a mail domain name. Consult with your provider to get the exact name of your back-up server, or just examine the DNS MX records for your domain: your back-up server is specified with the MX record that has the priority next to your own Server MX Record priority.

The ETRN command can be used to release your domain queue on a remote backup server only if your server has a static IP address. If your server has a dynamic IP address, the ETRN method does not work, since the backup server does not know the IP address your server is using, and the backup server is not able to open a connection to your server. If your server uses a dynamic IP address, it should use the On-demand Mail Relaying method to retrieve mail from the backup server.

When On-demand Mail Relaying method is used, your server connects to the backup server, authenticates itself, and then it issues the ATRN command. Then the servers exchange their roles and the backup server starts to send your server your domain mail via the same channel.

This eliminates a need for the backup server to open a connection to your server. Since the backup server does not open a connection itself, it has to verify that the server that sends the ATRN command and wants to retrieve your domain mail is really your server. Your server should provide some name and password that should be accepted by the remote server and that should allow your server to issue the ATRN command. Consult the remote server administrator to learn the name and the password your server should send before sending the ATRN command.

Use the colon symbol to separate the server name and the port number: mail. You can use secure communications with the backup server if you include the backup server name into the Send Encrypted list. Click that button to initiate a wakeup session immediately. It supports this protocol on all its ports, and it is not required to configure additional ports just to support LMTP. The CommuniGate Pro Server can be used as a back-up mail server for dial-up systems. Dial-up systems receiving mail via SMTP expect their back-up servers to receive and keep all their messages when these systems are off-line.

When a dial-up system connects to the Internet again, it connects to its back-up mail server and either issues the special Remote Queue Starting command ETRN, RFC , or sends a dummy E-mail message to a special address on the back-up server. This method allows a dial-up system to get its messages immediately, instead of waiting for your server to make the next attempt to deliver the collected messages.

No special setting is required, since this feature is always enabled. If you have routed the domain client. In a Dynamic Cluster environment, the ETRN command received by any cluster member releases domain queues on all cluster members.

Then the module releases the specified domain queue and sends all its messages directly via this already established connection. There are some notes about the ATRN implementation:. It is processed in the same way as the ATRN command without a parameter, and it requires authentication, too. The name of the queue to release is the same as the name of the authenticated user. In a Dynamic Cluster environment, the Wakeup E-mail received by any cluster member releases domain queues on all cluster members. You can ask the SMTP module to hold mail for certain hosts in its queue, and not to try to deliver that mail until the receiving server issues the ETRN command or sends a wake-up E-mail.

This can be useful if the receiving server is on a symmetric dial-on-demand line and its provider brings the link up automatically when there is any traffic for that receiving server. The situation when the SMTP module receives a message from a remote system and then sends that message to some other host is called relaying. If a message is to be delivered to the hostName host via a particular Instead, the Server places it into the This technique allows the Server to process messages from different Domains independently.

If the IP Address of one of your Domains is blacklisted by remote hosts because that Domain users have abused the mail system , messages to the same remote hosts from other Domains will not be delayed or rejected. If the hostname name is included into the Hold Mail for Domains list, the Server never adds the The module adds the domain blacklisted to each recipient address received from a blacklisted host, i. Then the address is processed with the Router as usual. If the Router Table does not contain special rules for the blacklisted domain, the address is rejected with a special error code.

This "white hole" feature allows the blacklisted host users to contact the postmaster on your server if they want to discuss the blacklisting issue.

If you remove this line from the Router Table, no address will be accepted from blacklisted hosts. If you want to provide a "white hole" feature, but you do not want the information about the white-hole address to be included into the error code, simply use a different name for the "white hole" address.

The following table contains samples of SMTP sessions established from a blacklisted host.

The SMTP module immediately on the first Router call accepts messages addressed to domain name -wakeup local addresses. When these messages are enqueued into the SMTP module queue, they are processed as wake-up requests for the domain name domain message queue. Please note that the Router adds brackets to the IP-address domain names that do not have them, and the Router changes the IP addresses of local domains to those domain names.

The Router performs these operations before calling the modules. The SMTP module immediately accepts addresses that have domain parts ending with the. This suffix is processed in the same way as the. On the final call, the SMTP module accepts mail to any domain if that domain name contains at least one dot.

If the Forward option is selected, all these addresses are rerouted to the specified Forwarding Server domain. Some mail servers can be configured to receive incoming SMTP mail on a non-standard port. The CommuniGate Pro SMTP module can send messages to those servers, if the domain part of an E-mail address contains the port number or is routed to an address that includes the port number.
