Email is an essential tool for communication, especially when running a website or business online. However, technical issues can sometimes disrupt access to your email account hosted on your web server. Troubleshooting and resolving email problems quickly is crucial to restore smooth operations. This comprehensive guide will walk through various common email issues on web hosting accounts and provide troubleshooting tips to fix them.
Checking Basic Email Settings
The first step when facing email difficulties is to verify that the basic email settings are correctly configured on your web hosting account. Here are key items to check:
- Login to your web hosting control panel and ensure the email addresses are set up properly under the email accounts section. All the existing email accounts should be listed here accurately.
- Navigate to the email settings and confirm that the POP/IMAP settings are correct for retrieving emails to your email client like Outlook or Thunderbird. The incoming and outgoing mail server names should match your web host specifications.
- Check that the SMTP authentication settings are enabled and username/password entered correctly for sending outbound emails via your web host. Typically, the username is the full email address, and password is the one set for that email account.
- Verify that the SPAM filter settings are not too restrictive. Overly strict SPAM filtering can sometimes block legitimate emails. Try adjusting the settings or disabling the filter temporarily to see if it fixes your problem.
- Test sending and receiving emails from the configured addresses on your web hosting account to confirm basic send/receive functionality is working.
Investigating Connectivity Issues
If you’ve verified the email settings are correct, next investigate potential connectivity issues:
- Try telneting directly to your web host mail server on ports 25 (for SMTP) and 110 (for POP3) to test basic connectivity. If the connection fails, it indicates a network issue in reaching your email server.
- Check your firewall, security software, and router settings are not blocking access to your web hosting provider’s mail servers. Add rules to allow connections if necessary.
- If on a corporate network, your company’s network policies could be restricting access to your web host. Contact your network admin or IT support to allow connectivity.
- For connectivity issues from a specific location, trace the network route to your web host mail server using traceroute to identify where the connection is failing.
- Check your web hosting control panel for any notifications of email server downtime or maintenance. Technical issues on their side can disrupt connectivity.
Troubleshooting Authentication Problems
If you can connect to your email server but have authentication issues when sending or receiving mail, try these tips:
- Reset your email account password in your web host control panel and re-enter it correctly in your email client/SMTP settings. Simple password errors are a common cause of authentication failures.
- If using SMTP authentication to send mails, verify your username (full email address) and password are correct in your email client. Also try toggling off and on the “Use SMTP Authentication” setting after correcting the password.
- Check that IMAP/POP authentication settings are properly configured in your email client, especially if you changed your mail account password recently.
- Ensure your account is not locked out due to multiple failed login attempts. Check your webmail or contact your web host support to unlock the account.
- Your web host may enforce extra security like 2-factor authentication, which can cause login issues if not set up properly for SMTP or mail clients. Confirm 2FA is enabled if required.
Fixing Incomplete Email Downloads
If your email client can connect to your web host mailbox but emails download partially or fail to sync fully, try these troubleshooting tips:
- Narrow down if the issue only occurs on a specific device/mail client vs. all clients. This helps determine if it’s a client-specific or account-wide problem.
- Clear the email client’s cache and force a full synchronization to re-download partial emails.
- Enable debug/log modes on your email client and check the connection logs for clues on where emails are getting cut off during download.
- Increase the amount of mail data downloaded per synchronization in your email client settings (e.g. number of days to synchronize, synchronization frequency, etc.)
- Check email storage limits on your web hosting account which can affect how much mail data can be downloaded to your client.
- Try connecting via POP or IMAP (whichever you’re not currently using) as an alternate protocol to retrieve messages from the server.
Identifying Outbound Email Blocking
If your emails go out but responses and incoming mails get blocked or filtered as spam, try these tips:
- Check your IP reputation and see if your web hosting IP address has been blacklisted on public DNS block lists due to previous spamming or abuse. If so, request de-listing or provision a new IP address.
- Examine email headers of undelivered messages for details on why recipient servers rejected or blocked it (e.g. spam filter triggers, routing problems etc.)
- Ensure your SPF and DKIM records are properly configured in your domain’s DNS to authenticate your outbound emails.
- Adjust your web host account’s SPAM filter settings to exclude false positives blocking legitimate incoming emails to your account.
- Contact your web hosting provider to understand if any issues with their outbound mail servers are impacting deliverability of your emails.
Troubleshooting Internal Email Looping
If emails sent between user accounts on the same domain result in infinite loops or duplicated messages, try these troubleshooting steps:
- Disable BCC (blind carbon copy) on any mailing list or group emails between accounts on your domain, as improperly configured BCC can cause looping.
- Check that each account is only configured to send and receive via your domain’s primary mail server hostname. Internal mail hand-off between multiple MX records can loop mails.
- In mail server logs, look for evidence of improperly configured mail forwarding rules or aliases that lack a termination condition, causing endless looping.
- Contact your web host to confirm the mail server is configured properly for your domains and accounts to deliver internal mail optimally without unnecessary forwarding hops.
Reducing Spam and Impostor Email
Unwanted spam and spoofed/impostor sender emails can be common problems. Here are ways to mitigate them:
- Enable SPF and DKIM on your domain to authenticate and prevent sender spoofing. Also enable DMARC reject policies to block impostor mails.
- Use RBL/DNSBL spam blocklists on your mail server to automatically reject known spam sources.
-Be vigilant against phishing by not opening suspicious attachments or clicking links, and report phishing emails.
- Avoid exposing your email address publicly on insecure sites to reduce your exposure to scrapers.
- Implement strong spam filters provided by your web host, mail provider, or email security vendor to automatically classify and block unwanted spam.
Seeking Help from Your Web Host
If you continue having email issues that you cannot resolve through troubleshooting, reach out to your web hosting provider’s technical support team. Be ready to provide:
- Detailed information about the specific email problem and when it started occurring.
- Screenshots of error messages or email client logs.
- Steps you’ve already tried to fix it.
- Email header samples showing delivery failures/rejections.
- Settings from your email clients and web host control panel.
Most shared web hosting providers offer 24/7 support and should be able to diagnose further and resolve most email problems on your account that you are unable to fix yourself.
Switching Web Hosts
In rare cases of persistent and unresolved email issues affecting your business on your current web host, you may need to consider switching hosts. When evaluating a new provider, pay close attention to their email delivery performance, uptime and redundancy capabilities, and technical support competency specifically for email services. The hassle of migrating domains and emails make switching web hosting providers a last resort option, but one you should still consider if email reliability continues suffering despite best efforts with your current host.
Email services are a mission-critical application for any business online. However, despite best efforts issues can sometimes arise that disrupt email capabilities. The tips in this guide provide a comprehensive starting point for troubleshooting and regaining control of your web host based email accounts. Pay attention to error patterns and behaviors to zero in on the specific problem, whether it’s connectivity, authentication, spam filtering, or other issues. With diligence and care, you can resolve most common email problems and restore smooth operations.
