Are your able to send Emails (messages) but not received?
Posted: Nov 14th, 2017
If you can send email but cannot receive email, there are several likely causes to investigate. These include email quota issues, your DNS settings and your email client settings. If your Plesk / cPanel has exceeded its disk quota, this can also prevent you from receiving email.
If your incoming email used to work and suddenly stopped working, the issue is probably one of the followings:
A) Email Account Quota
Each email account is created with a set quota, which is the amount of disk space allotted to a particular email address for email storage. This quota was set when you created or modified the email account in Plesk/cPanel and can be set to be unlimited or to a fixed size.
The most common reason incoming email might not be received is the email account exceeding its quota. To resolve this, you will need to increase the amount of disk space for that email account to receive mail again. Alternately, you can delete email in the email account until it is below the email quota.
Check Quota
To test your email account's quota:
> Send an email to the email account in question. If the mailbox is full, you will receive a bounceback message stating that the disk space has been exceeded.
> Check the email quota for the account directly by clicking on the Email Accounts icon in Plesk/cPanel. Check to make sure the Usage is not higher than the Quota for the account in question.
Change your Quota
To change an email account's quota:
Plesk
1) Log into PLesk
2) Select Mail (Left panel) or scroll down and click on Mail Addresses.
3) Click on email address for which you need to update the quota resources
4) Scroll down to MailBox, and either change it to Unlimited or increase its number.
5) Click Apply and then OK to save.
CPanel
1) Log into cPanel.
2) Navigate to the Email section.
3) Select the Email Accounts icon.
4) Scroll down to the email address for which you need to update the quota resources.
5) Next to the desired email address, click Change Quota.
6) Either type in the new quota amount or select the Unlimited option.
7) Click Change Quota.
Plesk / cPanel Account Over Quota
Another possible cause of not receiving emails is that the entire Plesk / cPanel is over its allotted disk quota. If this is the case, you will need to increase your disk quota to receive mail again.
Check Disk Space / Increase Account Quota
To check for accounts over quota:
Plesk
1) Login to your Plesk Admin Page
2) Select Subscriptions (left panel)
3) Select the Domain Name to be modified
4) Move to the right-side of the screen, scroll down until you reach the Account Section, then click on Customize.
5) Increase the Disk Space of the account along with the Mailbox size.
6) Click Apply and then OK to save
CPanel:
1) Log in to WHM.
2) Navigate to Account Information section in the left-side menu.
3) Select Show Accounts Over Quota.
You can also check the available disk space in a specific cPanel by looking for Disk Space Usage in the left-side panel. If disk space is maxed out or exceeded, you will need to raise the disk space quota on the cPanel's package by changing the package in WHM or by creating a new package and assigning it to the cPanel.
Increase Disk Space Quota
To increase your client's disk space:
1) Log in to WHM.
2) Navigate to the Account Functions section in the left-side menu.
3) Select Quota Modification.
4) Select the username or cPanel primary domain for the user whose quota you wish to modify.
5) Click Modify.
6) Adjust Disk Space Quota as desired.
7) Click Save.
Another option for adjusting account quotas in WHM is to:
1) Log in to WHM.
2) Navigate to Account Information section in the left-side menu.
3) Select Show Accounts Over Quota.
4) The account quota can be adjusted directly. Next to the quota field, you can also view the disk space used.
5) Once quota is adjusted, click Save.
2) DNS Causes
There are some common issues involving DNS that could cause email to not be received.
Propagation
If you recently updated nameservers, MX or A records, you may be experiencing the effect of propagation. Once the propagation period has elapsed, everything should work properly. For more information on propagation, see this article:
> Propagation Times
Incorrect DNS
Incorrect DNS records can affect how your mail functions. For information on DNS settings, see:
> How to Change DNS Zones (MX, CNAME and A Records)
Mail Server Settings
Please ensure that your mail settings are correctly set. You can have your mail and your website hosted at two different locations, but this requires correctly setting your mail server set as either local or remote.
Briefly, if you are using the local server based DNS, then you will need to have your mail server set as local. If you are outsourcing your mail through remote MX records or have mail directed to another server through A records, then you will need to make sure that you have the server setting to remote.
Mail Client Settings
Customers using MicroSoft-related email services (Outlook.com, Hotmail.com, MSN.com and Live.com) may note a problem with receiving emails from kekhost.com / kekhosting.com addresses via these services, while still receiving messages from elsewhere. Contact us should you need further assistance via our Customer Support Portal.
If you are using a third party mail client, make sure that the incoming mail server settings and ports are correct. If these settings are incorrect, you will still be able to receive your mail via webmail; however, you will need to rectify the account settings in your mail client so that you may begin to receive your mail again.
You might also try closing out the program and reopening it, as it is possible that your mail client might be malfunctioning or has not saved your settings.
