Hello everyone,
Intermittently I get errors logged like in subject while mail is locally
spam-scanned (traditional method of external scanning and the mail
filter re-injecting the message with exim -oMr spam-scanned -bS). This
causes a bounce to be generated and obviously makes bad impression among
users.
Does anybody know the cause behind it?
The bounce excerpt:
....
> local delivery failed
....
>
> An error was detected while processing a file of BSMTP input.
> The error message was:
>
> 421 SMTP incoming data timeout - message abandoned
>
> The SMTP transaction started in line 0.
> The error was detected in line 3.
> 0 previous messages were successfully processed.
> The rest of the batch was abandoned.
> 421 SMTP incoming data timeout - message abandoned
> Transaction started in line 0
> Error detected in line 3
