+- Tests remaining: 6
+
+### Remaining Tests to Fix:
+1. test.ccm-05.connection-reuse.ts - SMTP client connection
+2. test.cperf-05.network-efficiency.ts - SMTP client performance  
+3. test.cperf-06.caching-strategies.ts - SMTP client performance
+4. test.cperf-07.queue-management.ts - SMTP client performance
+5. test.cperf-08.dns-caching.ts - SMTP client performance
+6. test.crel-07.resource-cleanup.ts - SMTP client reliability
+
+### Fixed Tests (28):
+- **Edge Cases (1)**: test.cedge-03.protocol-violations.ts ✓
+- **Error Handling (4)**: cerr-03, cerr-05, cerr-06 ✓
+- **Reliability (6)**: crel-01 through crel-06 ✓
+- **RFC Compliance (7)**: crfc-02 through crfc-08 ✓

+### Important Notes:
+- Error logs are deleted after tests are fixed (per original instruction)
+- Tests taking >1 minute usually indicate hanging issues
+- Property names: use 'host' not 'hostname' for SmtpClient options
+- Always use helpers: createTestSmtpClient, createTestServer
+- Always add tap.start() at the end of test files
