[BlueOnyx:21482] Outbound on submission port

[Colin Jack]

We have a number of customers using BX servers for their in-house email servers.
We are now looking at supplying a cloud based filtering service and it requires outbound mail to be sent on the submission port (587) to their servers.
They provide instructions for modifying sendmail.mc but on BX this would be overwritten:

For this you have to edit /etc/sendmail.mc and add the following lines at the top under the "divert(-1)dnl" line:
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
define(`SMART_HOST', `[SMART.HOST.TLD]')dnl
Run "sendmailconfig" to use this new configuration. This will automatically re-start sendmail.

What can we do?

Thanks

Colin
