Configuring the SMTP Proxy
as large as 1MB (1000Kb) you must set this field to a minimum of 1.4MB (1400Kb) to make sure all
email messages and their attachments get through.
Maximum line length
Set the maximum line length for lines in an SMTP message. Very long line lengths can cause
buffer overflows on some email systems. Most email clients and systems send short line lengths,
but some web-based email systems send very long lines.
Deny Message
In the Deny Message field, you can write a custom plain text message that will appear in the recipient
email message when the proxy blocks that message. You can use these variables:
%(type)%
Puts the content type of the email message.
%(filename)%
Puts the name of the attached file.
%(virus)%
Puts the type of virus found.
%(action)%
Puts the action taken by the proxy policy.
%(reason)%
Puts the reason the proxy policy denied the content.
