Sendmail Error EX_TEMPFAIL | Resolved

by | Feb 18, 2024

An email message delivery attempt that is temporarily unsuccessful is shown by the Sendmail error “ex_tempfail”. At Bobcares, with our Server Management Service, we can handle your issues.

Solving Sendmail Error “EX_TEMPFAIL”

The Sendmail error “ex_tempfail” denotes a brief breakdown in email message delivery. When Sendmail has a problem delivering an email, it reports this error. The message will be resent at a later time, and the failure is anticipated to be brief. Sendmail employs the standard exit status code “ex_tempfail” as a means of reporting delivery problems. Depending on its retry configuration settings, Sendmail will attempt to deliver the message again after facing this issue. Some of the reasons for the error include:

sendmail error ex_tempfail

1. Recipient Mailbox Full: Sendmail is unable to deliver the email if the recipient’s mailbox is full. Being overflowing in the mailbox is typically a passing mood. Sendmail will make another attempt to send the message later.

2. Network Issue: An irregular network problem between the mail servers that send and receive messages can result in the “ex_tempfail” error. This can be the result of DNS conflicts, network congestion, or other connectivity issues.

3. Resource Constraints: Temporary email delivery failures may arise from resource constraints on the sending or receiving mail server, such as a heavy load or insufficient disk space.

4. Greylisting: Greylisting is a spam prevention technique used by certain mail systems. An inbound email is temporarily rejected by greylisting with a “soft” error, allowing the sending server to attempt delivery again at a later time. While many spam sources do not retry, legitimate email servers usually do.

5. Temporary Mail Server Outage: The delivery failure may have been the result of a brief outage or maintenance on the recipient’s mail server.

Solutions

Sendmail will use its retry rules to attempt sending the email message again in order to manage the “ex_tempfail” problem. Sendmail will attempt delivery by default for a few hours, with longer intervals between attempts. In the event that the problem is brief, one of the next retries will probably result in the message being delivered correctly. Also, we can try these steps to fix the issue:

1. For more specific details on the delivery failure, look through the Sendmail logs, which are typically found in /var/log/mail.log or /var/log/maillog. The logs might offer hints regarding the precise reason for the brief failure.

2. Generally, it’s better to wait and let Sendmail take care of the retries on its own. If this is really a transitory problem, a later attempt to deliver the email should likely succeed.
