Hi Lutz,
Please log in as the Sys Admin and check these two areas:
Go to Settings > Antispam. On the Options card, you'll find a setting titled "Autoresponders". This setting allows you to add restrictions to a user's ability to create or send autoresponders outside of the domain.
- Enabled - Users' autoresponder messages will be sent without any restrictions.
- Disabled - Users will not have the ability to configure an autoresponder.
- Require message pass SPF - A user's autoresponder will not be sent if the original sender's message failed the SPF spam check or if the sender's SPF record is not configured. Note that this setting won’t impact the ability for an incoming message to be delivered to your users. It will only prevent the user's autoresponder from being sent if the original sender's SPF record is not configured or if the SPF check has failed. Note: The SPF spam check must be enabled for spool filtering in order for this setting to work as intended. If the SPF check is disabled, and this setting is enabled, autoresponder messages will not be sent.
- Require message pass SPF if SPF record exists - A user's autoresponder will not be sent if the original sender's message failed the SPF spam check. Note that this setting won’t impact the ability for an incoming message to be delivered to your users. It will only prevent the user's autoresponder from being sent if the original sender's SPF check fails. (This option is distinguishable from the option above as it will only impact messages where the SPF record IS configured and fails the check. If the original sender doesn’t have SPF configured, the autoresponder message will be sent.) Note: The SPF spam check must be enabled for spool filtering in order for this setting to work as intended. If the SPF check is disabled, and this setting is enabled, autoresponder messages will not be sent.
Go to Domains and edit the domain in question. On the Email card, you'll find a setting titled "Autoresponder Exclusions". You can use this setting to prevent SmarterMail from sending automated messages based on the spam level of the original message. If this is set to an exclusion, you can review the emails that did not receive an autoresponse and determine if their spam level was the reason.
You can also impersonate the user and review their autoresponder settings directly. Make sure it's enabled, and make sure that both textboxes contain the response. If "Disable responses to indirect mail" is enabled, the autoresponder will only be triggered by email sent directly to the user. Any email received through a mailing list, forward, or an alias will not trigger the autoresponder. Finally, please take note of the warning that autoresponders are only sent once per day per sender.
If you're still having trouble after reviewing these areas, please submit a support ticket so we can help you look into this directly.
Kind regards,
