UPDATE: The SPF record I have in DNS for domain mailinglist.com:

mailinglist.com. 3600 IN TXT "v=spf1 mx ptr include:gateway.com ?all"

UPDATE2: The From:, Reply-To:, Sender: and Return-Path:headers from a failed message:

...
From: "bob" <[email protected]>
Reply-To: <[email protected]>
Sender: <[email protected]>
List-Post: <mailto:[email protected]>
Return-Path: [email protected]
...

I've inherited a Sympa mailing list server from a previous Admin and am not very familiar with the whole process. Recently, we've been getting some calls from users that their posts to the various mailing lists are being marked as failing fraud detection checks.

I've been reading up on SPF and suspect that what is happening is when a user ([email protected]) posts to the list (my.mailinglist.com), the outbound message from the list server has the envelope sender set to "[email protected]". Our list server then relays the outgoing message to mail.gateway.com which then delivers it over the Internet. When the SMTP server at somewhere.org (or other domain) receives the post, it sees that it was sent by our relay, mail.gateway.com (13.14.15.16), which does not have it's IP address on the SPF record for somewhere.org.

In the mail headers of the outbound post sent from mail.gateway.com, I have an SPF line which reads:

Received-SPF: SoftFail (mail.gateway.com: domain of
 transitioning [email protected] discourages use of 13.14.15.16 as
 permitted sender)

We have many users from many different domains sending mail to our list server. Asking every domain to include the mail.gateway.com IP in their SPF record seems ridiculous, but that's what I gather is one way to fix this.

The other fix involves probably using a different envelope sender. I'm not sure how this would affect "Reply" and "Reply to" functionality. Right now it seems a bit wonky; Reply and Reply-to both go the the mailing list which seems odd. I'm trying to figure out where that is configured.

Are there some other ways to work this out that I have missed? Thanks

I was wondering if it's possible to notify users who have had messages distributed in the same way that if a user gets rejected they get a notification.

There doesn't appear to be any way to turn the feature on.

I have setup sympa with postfix. I am having problems with creating lists. Everytime I create a list I get this in my /var/log/apache2/error.log:

    postalias: fatal: open /etc/aliases.db: Permission denied  
    Failed to execute newaliases: Inappropriate ioctl for device

I tried removing aliases.db and manually using postalias, but alas. The problem doesn't show however when I restart postfix, so I think it is the fast cgi script trying to update the alias files for postfix.

I have set up a Sympa list serv server and everything is working fine for the most part. One issue that I am running into is sending files over ~580 KB in size (just a normal .txt file) are not going through. I am getting the following error.

Impossible to distribute your message for list 'list-name' because of an internal server error.

I have verified that my "Maximum message size (max_size)" setting in Sympa is get to 5 MB so that shouldn't be the problem. If I try sending the same .txt file after taking out a few lines, and the file size is ~530 KB, then it works just fine. Any help would be greatly appreciated.
