Template Based Feed Email Delivery Failing / SSL Read Timeout (MER-UTL-PUB-00002)

[William Davis]

Hi all, hoping someone can help or confirm expected behavior / best practice.

I am using a Template Based Feed to generate a consignor-only report. The feed output itself works correctly (pipe-delimited output, correct filters, no syntax errors).

Goal:
- Generate a private consignor report feed.
- Deliver it by email (inline or attachment) securely.
- Avoid public URL access.

Setup:

• Feed Module: Template Based Feed
• Enable URI Access: OFF
• Enable File Creation: ON
• File Location: Data (Private)
• File Path: /consignor-report-CON-0208-ADJv7.csv
• Enable Email Creation: ON
• Email From: Service@<mydomain>.com
• Email Reply-To: Service@<mydomain>.com
• Email To: Jerry_<last>@<mydomain>.com
• Email Subject: Consignor Report: CON-0208-ADJ

Mail Settings in Miva (global):

• Mail Server: smtp.office365.com
• Encryption: STARTTLS
• Port: 587
• Transactional emails from Miva already work reliably for years (order notifications, etc.)

Issue:

1. When Email Type is set to Inline:
   1. Feed run completes with no error, BUT no email is received (not in Inbox/Junk).
2. When Email Type is set to Attachment:
   1. Feed run fails with error: MER-UTL-PUB-00002: SSL Read Timeout
   2. (I have also seen SSL Read Timeout in feed log during certain runs.)

Notes:

• The feed output works and produces valid data.
• The issue appears isolated to Email Creation from Template Based Feeds (transactional emails continue to work normally).
• I cannot find the Data (Private) file via FTP (expected), but I also cannot get reliable email delivery.

Questions:

• Is there a known limitation or best practice for email sending from Template Based Feeds (especially attachments)?
• Does Attachment mode trigger outbound SSL behavior differently than normal mail sending?
• Is there a payload size/content limitation causing the timeout?
• Is there a recommended secure pattern for delivering private feed output (Data Private + portal page, etc.)?

Any insight greatly appreciated.

Were the errors only occurring yesterday or they're consistent both before and after? Microsoft email was mostly down for six or seven hours yesterday afternoon through evening, so those SMTP settings were likely failing during that time.

If it's consistently failing, the issue is still possibly the Microsoft SMTP server if the size of this file is large or the generation takes a while. Their server has both an intentional delay at connection time to discourage its use by any type of transactional system; 10+ seconds. It also has a limited connection time. You could be hitting the connection timeout before completion occurs.
