Some email systems and IMTAs encounter problems when handling large messages. You can control how the channels handle large messages (measured in bytes and number of lines) for the SMTP intranet/internet channels, SMTP explicit route channels, and local or message store channels (for other channels, this feature has no effect). You can specify that messages be limited by size, number of recipients, or that they be fragmented if they exceed a certain size.

| 1. | In the Sections list of the Channel property book (see "To Access Channels Property Book" on page 121), click Message Limitation. |
To set local user to local user mail message limitations, configure the local (Solaris Message Store) or message Store (Sun Message Store) channel depending on the recipient's channel. Note that the local and message Store channels do not support either of the Fragmented submitted msgs parameters or the Max. no. of recipients per msg parameter.
| 2. | (Optional) Set limit on message size. |
| 3. | (Optional) Set limit on the number of lines in incoming messages. |
You can specify a limit at which a message should be fragmented into smaller messages and a limit at which a message should be deemed too large and rejected. The default is unlimited.
| 4. | Set limits on the maximum number of recipients per message by typing a value. |
| Valid entries include 0 to 32,768.By default, a channel handles up to 32,268 recipients per message. If desired you can specify a limit at which a message is deemed to have too many recipients and is rejected. |
