Forum OpenACS Q&A: Issues with acs_mail_lite::send to gmail addresses

1: Issues with acs_mail_lite::send to gmail addresses

Posted by Keith Paskett on 04/21/23 04:28 AM

I have acs_mail_lite smtp set to a postfix instance. When I attempt to send to an address hosted on google's gsuite, I get the following logged by postfix. (I've obfuscated some hostnames and IPs

Apr 20 19:40:25 pfserver postfix/smtp[8722]: [ID 197553 mail.info] 58A5D2A75F: to=<mailto:info@company.org>, relay=aspmx.l.google.com[74.125.197.27]:25, delay=0.61, delays=0.05/0/0.3/0.26, dsn=5.7.1, status=bounced (host aspmx.l.google.com[74.125.197.27] said: 550-5.7.1 [xxx.xx.xxx.179] Messages missing a valid messageId header are not 550 5.7.1 accepted. x5-20020a654145000000b005130d9f6e66si2904300pgp.366 - gsmtp (in reply to end of DATA command))

If I send a message to the same address using the mailx command, it get delivered without errors. Also email sent with acs_mail_lite::send to addresses not hosted by google, are delivered without error.

Any ideas?

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.

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?
