Why can’t I send emails?

There a couple of reasons why you will be unable to send emails:


Your ISP is blocking port 25

If you can't send an email and you're utilizing a business Internet Service Provider (ISP), they might block SMTP port 25. This port is standard for sending an email. But on the other hand it is standard for sending spam, so ISPs frequently block it. Verify whether your ISP is blocking port 25:

1. Open Command Prompt (in Windows) or Terminal (Mac OS).

2. Enter the code: telnet exampleDomain.com 25

3. If port 25 is not blocked, at that point you will get a successful 220 reaction. If port 25 is blocked, at that point you will get an connection error or no reaction by any means.

4. If port 25 is blocked, you can then again utilize port 587. You should change this inside your email client  and is typically designed inside "preferences" or "settings".


Check that your email account data and settings are correct

Ensure the email account username and password that you enter in your email client are right. To check this data:

1. Sign in to Hamro.Cloud

2. Select the package of the email account you need to discover

3. Select 'Email Accounts'. Here you can change the password, and after that check the new password


Verification

Your active mail server ought to be set up to verify using your password, and ought not be using SSL.


Outgoing Mail Server

In case you're utilizing Hamro.Cloud to send email, you'll have to ensure that you're using either mail.[domain], or smtp.stackmail.com as the active mail server.In the case of  mail.[domain], you'll need to change this to your real domain, for example mail.yourdomain.com.


Firewall/Antivirus

Solid firewall or antivirus software  might be blocking messages from being sent.If you think your antivirus may prevent emails from being conveyed, the fastest arrangement is to temporarily impair the firewall or antivirus software. While debilitated, try sending a test email, check whether it sends, and afterward turns your security software back.

In the event that the test email sends, at that point you may need to survey the documentation accessible for the firewall/software to check whether there's an approach to sidestep the restriction.


Email Limits

Our mail stage has a few points of confinement set up so as to secure the reputation of the mail stage and prevent expansive amounts of spam sends being sent. At present our mail limits are as per the following:

Web servers: 500 messages every day.

Mailboxes: 8000 messages every day.

Message size/attachments: The webmail system acknowledges connections up to 32MB in size, and the most extreme message size in our network is 50MB.

In the event that any of these cutoff points are broken, it won't be conceivable to send letters from that hosting package or mailbox. On account of the message size/connection limit, you'll essentially need to look at decreasing the size of the email or the connection being sent.


Blacklisted IP Address

If the machine you're sending mail from has a blacklisted IP address, you won't probably send email if the provider you're sending to effectively watches that specific blacklist. There are various instruments accessible online that can disclose to you the IP address of your machine and regardless of whether that specific IP address has been blacklist. Much of the time, you'll have to ask for delisting from the blacklist being referred to.
