SMTP block for single user

[Richard G]

I want a certain user to use the smtp server of his own internet provider. To force him to do that, I would like to block the option for him to make use of the smtp of our hosting server.

Is this possible? And if yes, how?

See Edit#26 in SpamBlocker 4.x. You'll need to write a custom ACL to block email from all the user's logins before doing the authentication on port 587. Where it authenticates against auth_relay_hosts, include a separate file with hosts to not allow. Also Edit#16, don't allow pophosts (which will break pop before smtp). Or create even more customizations.

Or make it a TOS violation to continue to use it after being blocked for cause, and then terminate his account. Probably easier.

Note I've NOT studied the details. Nor have I looked at earlier examples of SpamBlocker.

As John usually recommends in such a case, set limit of 1 for the user account then:

echo 1 > /etc/virtual/limit_username

replace username with your account's real name. Note 0 here would be understood as no limit at all.
