The delays in sending emails, especially to external domains, can often be linked to issues like server load, throttling, or reputation problems with your SMTP provider. It’s important to analyze the sending patterns that coincide with the failures.
A timeout error usually indicates that the server is taking too long to respond. This can be due to high server traffic or misconfigured settings on the SMTP server.
To troubleshoot, check if your SMTP provider has guidelines on sending limits or if there are any reported outages or maintenance notices. Understanding your provider’s sending limits can help avoid delays.
Using tools for email queue management or service monitoring can help keep track of your email sending status. Also consider contacting your SMTP provider’s support for deeper insights.
