address.
Maximum Message Size
Specifies the maximum size of an incoming SMTP
message. Note that most email is sent as 7-bit
ASCII text, with the exceptions of Binary MIME
and 8bit MIME. 8-bit content (for example, MIME
attachments) are encoded using standard
algorithms (Base64 or quote-printable encoding) to
enable them to be sent over 7-bit email systems.
These types of encoding causes an increase in size
of approximately 1/3 for encoded files. Therefore,
if you want to allow messages of up to 1000 bytes,
you should set this field to a minimum of 1334
bytes to ensure that all mail gets through.
The default is 3,000,000 bytes (3 million bytes).
Maximum Address Length
Specifies a maximum length for addressee email
addresses. Restricting email address size can
prevent some buffer overflow exploits from being
used. The default is 50 bytes.
Maximum Line Length
Specifies the maximum line length for lines in an
SMTP message. Very long line lengths can cause
overflow conditions on some mail systems. Most
email clients and systems send relatively short line
lengths, but some web-based email services send
very long lines. The default is 1024.
Connection Idle Timeout
Specifies the amount of time an incoming SMTP
connection can idle before the connection is timed
out. The default is 600 seconds (10 minutes).
Address Validation (RFC-822 Compliance)
Allowable Characters
: Allows you to specify all of
the characters that are allowed in incoming email
addresses. If there are particular characters that
