Troubleshooting eForm Attachments That Never Reach the Inbox

Sometimes eForm appears to work: the submission goes through, the email is sent, but the attachment never reaches the inbox. In older Evolution projects this usually came down to one of three things: form markup, attachment handling, or mail transport limits.

What to Review

• the form must use enctype="multipart/form-data"
• the file field must match the expected eForm configuration
• server upload limits must allow the attachment size
• mail transport or SMTP policy may strip or reject attachments

Debug Order

1. Confirm the file reaches $_FILES.
2. Confirm eForm receives the file field correctly.
3. Check whether the server can write temporary upload files.
4. Review mail transport logs if the attachment disappears later.

Most attachment bugs are not mysterious. They are just split across form handling and mail handling, so both layers need to be checked deliberately.
