 |
|
Hi,
I want to send mail with sendmail through a MS Exchange server (relay).
How do I login to this server using sendmail??
ehlo output of the exchange server:
| Quote: | 250-ex.domain.com Hello [172.28.0.1]
250-XEXCH50
250-HELP
250-ETRN
250-DSN
250-SIZE 8192000
250-AUTH LOGIN
250 AUTH=LOGIN |
Thanks a lot. |

Sendmail is an MTA much like Exchange itself. I suppose you could hack something together to make Sendmail login into Exchange, but I'm not sure that you would need to. You would need to tell Exchange that the IP address of your Sendmail machine is allowed to relay mail and then configure Sendmail to use Exchange as the relay.
Unfortunately, I've usually done it the other way around for scalibitlity reasons.

Well, I have to write a script to automatically send mails.
| Code: | /usr/sbin/sendmail -t -n << EOF
From:blubb
To:abc
Subject:test
abcde
EOF |
This mail should be relayed through the exchange server.
Any Ideas?
I found a howto, but the mail will not be send cause sendmail couldn't find the dns hostname of the exchange server. 
Thanks a lot |

You will need to turn smtp relaying on for the IP address of the machine running sendmail.
After that you will need to tell sendmail to use the exchange server to deliver messages instead of doing so directly. You can do this in sendmail.cf or if you are scared of that file like me you could use webmin :) |

this is a part of the logfile:
| Quote: | Aug 14 18:08:10 proxy2 sendmail[9337]: alias database /etc/aliases rebuilt by root

I also changed /etc/nsswitch.conf:
hosts: files [NOTFOUND=continue] dns
to search the /etc/hosts firstly but it's not working at all. |

Looks like DNS resoltuion problems. Add an entry for the 172.x.x.x machine into your /etc/hosts and then change your smart relay to the host name you've entered.

Hi... could you post a link to this how-to? I'm trying to setup bugzilla to go through an exchange server, but it only works with sendmail (or so I have read,) so I would like to know how to do this.
Thanks.
