| 14 | # testing. When soft_bounce is enabled, mail will remain queued that |

| 15 | # would otherwise bounce. This parameter disables locally-generated |
---|
| 16 | # bounces, and prevents the SMTP server from rejecting mail permanently |
---|
| 17 | # (by changing 5xx replies into 4xx replies). However, soft_bounce |

| 173 | # |
---|
| 174 | # The default setting assumes that you use the default Postfix local |

---|
| 176 | # local_recipient_maps setting if: |
---|
| 177 | # |
---|
| 178 | # - You define $mydestination domain recipients in files other than |

| 180 | # For example, you define $mydestination domain recipients in |

| 182 | # |
---|
| 183 | # - You redefine the local delivery agent in master.cf. |

---|
| 185 | # - You redefine the "local_transport" setting in main.cf. |
---|
| 186 | # |
---|
| 187 | # - You use the "luser_relay", "mailbox_transport", or "fallback_transport" |
---|
| 188 | # feature of the Postfix local delivery agent (see sample-local.cf). |
---|
