The 'MailConvertMimeOnTransfer' setting can force message format conversion
from MIME to the native Notes Rich Text format (also known as CD records).
Values are as follows ...
0 = Router does not perform conversions for MIME messages
1 = Router performs conversions for all MIME messages
2 = Router performs conversions depending on the individual Person document
settings. If the options for "Prefers Mime" or "Keep in
Sender's format" are set in the recipient's Person document, delivered
messages are kept either in MIME or the sender's format.
The Router usually preserves incoming message formats. If the incoming
format is MIME, the router will only convert it if the destination server
is running version 4 (which doesn't understand MIME), or the recipient
'prefers Notes Rich Text' via their Person document. Setting MailConvertMimeOnTransfer=1
will cause the Router to convert all MIME messages to Notes Rich Text when
they are transferred to another server, regardless of the version. This
makes an R5 SMTP hub behave more like an R4 MTA, where all content is always
By Default, the Router will NOT convert MIME to native format unless required
to do so.
When this setting is absent or set to 0 the Router will preserve message
Use of this setting should be discontinued. Completely remove it from all
NOTES.INI and configuration documents.

No restart necessary. Force the configuration change to be noticed by the
router via the following server console command:
tell router update config
