Known Issues

Description:

When UNIX socket is used for communication between the filter and Sendmail, Milter API library (distributed with Sendmail) could not remove (prior to version 8.12.2) the file used for the socket.

Solution:

For versions 8.12.x the following patch is available - listener-8.12.0-1.patch. For versions 8.11 and later, this file must be removed manually or via script which manages filter operation. The issue is resolved in Sendmail version 8.12.2

Description:

When demo key is used in the local scan mode, the size value of a message which is transmitted to the next server is doubled after passing through the filter (the message itself either remains unchanged or a small "banner" is added to it).

Solution:

This issue is resolved in Sendmail version 8.12.3 and later.

Description:

When the filter operates on computers with high load, the following entries can be found in the log:

... Milter (drweb-milter): select(read): interrupted system call

Solution:

This issue is resolved in Sendmail version 8.12.3 and later.

Description:

When the filter operates on computers with high load, the following entries can be found in the log:

... Milter (drweb-milter): select(read): timeout before data write
... Milter (drweb-milter): to error state

Solution:

The problem is that Sendmail cannot establish connection with the filter within the specified timeout. In versions 8.11 and later the timeout is set to 5 seconds and cannot be changed. In versions 8.12 and later this timeout can be changed in the description of the filter (the C value):

Xdrweb-milter, S=__ADDRESS__, F=T, T=C:1m;S:5m;R:5m;E:1h
