I would recommend configuring the package parameter "EmailDeliveryMode" of acs-mail-lite to "nssmtpd" and install the NaviServer module nssmtpd. This solved several issues for us. It also supports debugging of the mail server communication by activating log severity "Debug(smtpd)"

That didn't solve the problem, but logging did give me some more clues.

It appears that the google mail server doesn't like the message-id created for email addresses that are not associated with ACS users.

When I added a user with the email address of my google group, then emails would send.

If there is a user with the email address, I get a message-id like the following and google accepts the email.
Apr 21 10:25:03 pfserver postfix/cleanup[21735]: [ID 197553 mail.info] A08FF2AD46: message-id=<mailto:20573.46157836076.18-281+1682699103+59A2ABE1E65FC5B55A5A3DA756E4A8704CD23658@logansw.com>;

If there is no user with the email address, the message-id is as follows and it gets rejected.
Apr 21 10:41:45 pfserver postfix/cleanup[21874]: [ID 197553 mail.info] 01E022B6D3: message-id=20573.1682095304.1@logansw.com

Actually the message-id that works does not start with mailto: in it. That's being added by the OpenACS Forums code.

It should just be:
message-id=<20573.46157836076.18-281+...

Hmm, can it be that you have some older version of the forums in place, or some local modification? I can't find a code, where "mailto:" is added to the message-id. Or, maybe, it this coming from some parameter?
