Unfortunately, it didn't work - the email was bounced with:
host 127.0.0.1[127.0.0.1] said: 554 5.4.0 Error:
too many hops (in reply to end of DATA command)
Looking at the mail logs it looks like the following is happening (excuse my dumbness with postfix/smtp):
- web client sends email to the local smtp
- local smtp relays to localhost:587
- email gets forwarded to dkim process on 10027
- dkim signs the process and forwards to port 10028
- postfix picks up the email from port 10028 and forwards it onto the local smtp, which goes back to the beginning of this sequence
this appears to continue until the max number of hops is reached and the email is then bounced.
Any clues from the more knowledgeable zimbra/postfix gurus as to how to get past this? |
