Sendmail & omsendin - how to change the configuration

[Shaun]

Hi everyone.

I'm currently implementing a scalix community edition server (latest version as of 12th Nov 2007), and I'm hoping someone can help me with sendmail running on OpenSuSE 10.1

I've used sendmail extensively, and I'm used to m4 files. From what I understand from these newsgroups, there is a command called omsendin, which overwrites the current sendmail.cf with a scalix friendly one. I'd like to use my own modified sendmail.cf, as this particular box is for a satillite company and has no DNS, so I want to prevent DNS support. Can someone tell me what changes Scalix makes to the sendmail.cf file so I can place them in manually? - Or, if possible, let me know the changes you have to make to the m4 file!

Many Thanks

[Shaun]

I cheated - edited the omsendin script to read my version of the mc file.

Could you share your omsendin version.

Sure - it's nothing special though...
