Additional Information

Steps to duplicate:

  1. in the gwia.cfg enter the following options:
  • --flatfwd
  • --realmailfrom
  1. the gwia should be using a relayhost.
  2. restart the gwia.
  3. start a groupwise client and log in as a user.
  4. create a rule that will forward an incoming mail to an external mailbox. I tested with a none-existing mail address (e.g.: blablabla@blabla.bla)
  5. send a mail to this mailbox from external. This will cause the loop.....
Checking the messages that are bounced, the root cause can be discovered. When using the option --realmailfrom the return-path will be replaced by the address of the groupwise user. This will also be done when the mail is a undelivered mail notification. According to the smtp rules, these type of mail should have a empty return-path, which will prevent the loop.
