Issues: I had a CE-03 error after scanning. Looking at the /var/log/maillog on my postfix server I saw a timeout exceeded error.
To be more specific, the error in the maillog file was:
postfix/smtpd: > unknown[10.3.10.109]: 421 myserver.mydomain.com Error: timeout exceeded postfix/smtpd: timeout after EHLO from unknown[10.3.10.109]
I changed the value of smtpd_timeout in /etc/postfix/main.cf:
smtpd_timeout = 35s
It was only 15s before.
And to apply the modification:
Then it worked, I received my scan by email but I didn’t realized right away because the e-mail arrived with a wrong timestamp.
So I set the scanner clock and everything went fine :-)
Comments in French, Portuguese, Spanish, Italian or Romanian are also welcomed.
