SMTP server returned error “Illegal address syntax from unknown in MAIL command:” when emailing the historical logs from an EGX300
Issue
The SMTP server returned the following error:
Nov 26 09:16:03 ip-10-10-20-165 postfix/smtpd[23309]: warning: Illegal address syntax from unknown[192.168.0.64] in MAIL command: test@Schneider-electric.com
Also, the diagnostic page of the EGX300 shows a "connection error" under the SMTP portion.
Product Line
EGX300
Environment
EGX300 built in webpage configuration
Cause
The From Address: and To Address: are not in a format that the SMTP server recognizes.
Resolution
Add the signs "<" and ">" to the From Address: and To Address: fields.
Now, verify proper email operation.
Special Note.
The EGX300 is now obsolete. The replacement product is the EcoStruxure Panel Server product line, Panel Server PAS800 suggested.
