I created a mail list in sympa. When I send email with attachement to this list via thunderbird, it's successfully delivered to the subscribers. When I send email via Gmail web interface, attachement doesn't reach subscribers, only message text. Source of outgoing gmail message is attached.
First message was truncated. Sending full message
Hello Alexander,
did you find any information about why this email didn't get send to the lists in the log files?
Regards
Racke
