outgoing mail [SOLVED}

[viking]

Hi there,

We have a Lotus Domino server running. The SMTP server is based in Taiwan,and locally we have an OU server for mail. (routating local mails and send mails to router in Taiwan).

I want to use Scalix more as a database for contacts per department and reminder scheduler. So it's main purpose is NOT sending mail.
Ofcourse there are maybe other progs with what you can do the same as I want, but I like Scalix. Easy setup etc and users can easilly access the contact list via web.

For the scheduling part, Scalix have to sent an email to the users as notification. The users will have a local emailaddress only for Scalix and an emailaddress for Lotus notes. The schuduler notify have to be send to the Notes emailaddress. But how do I configure that?

I have a DNS server running on windows. Can I add a slave dns server on the linux box with only the MX record?

I'm pretty new to setting up a mailserver.

Hopefully somebody can guide me how to accomplish my request.

Thanks in advanced

What I basicly want is to send a mail from internal emailaadress created on Scalix to a valid emailaddress.
The internal address is not a registred one, so reply to that emailaddress will always fail.

Is this even possible?

Yes, this is certainly possible.

two issues at hand.

1. your outgoing sendmail MTA on the Scalix serverwill check the sender adress against DNS. You will need to disable the check. I believe the sendmail option is something like "accept_unresolvable_domains", but please google on the subject. easiest to test would be to try to send a message and check the logs for the actual error message, then google for that.

2. depending on the configuration of your Notes SMTP MTA, this might reject unresolvable sender addresses as a means of spam protection. you'll probably need to somehow "whitelist" your local domain there. I'm not a notes guy, so i don't know how exactly this is to be done.

Sorry for only saying "yes" and give such rough pointers, but this probably needs some detailed investigation and testing to get it up and running actually.

Cheers,
Florian.

Thanks.

You already helped me alot. I'm new to sendmail and Scalix. I didn't even know if it was possible to send 'fake addresses' to real addressess because of DNS and Spam.

For Lotus Notes...we have a seperate spam filter so it's no problem to put the 'fake address' created on Scalix, on the whitelist.

Thanks so far.

What I did:

Adding the domain to /etc/mail/local-host-names and modified sendmail.cf to have Fw/etc/mail.local-host-names so sendmail can resolve the hostname. (or adding domain to host file).

Add the sending user to /etc/mail/trusted-users and modified sendmail.cf to have Ft/etc/mail/trusted-users so that I don't get warnings in my maillog.

thanks to Gilead!!
