Author Topic: forward messages to external SMTP server with userid domain/username  (Read 802 times)

Hello Everyone,

we are trying to forward message from PMTA Server to other SMTP Server.
we have to use user name in below format(auth-username domain\rashmi), as our external SMTP server gives access to one of our service account.
so while forwarding mail we are getting error "x-pmta;AUTH failed with "535 5.7.3 Authentication unsuccessful" ".

How to give username which includes domain? we have tried using double quote, double slash, but no lock.

         <domain *>
      smtp-hosts [a.b.c.d]:25     #routing
      auth-username domain\rashmi
      auth-password parida

I'm not sure that will work, but can you turn on log-commands for the <domain>, try again, and then post the logged data?
Try the following commands:
pmta show topdomains --errors
pmta show topqueues --errors
pmta --help

When PowerMTA won't start use:
pmtad --debug
When all else fails-->support@port25.com
