Hi, I run a mailing list using Macjordomo with SIMS as my mailer. For one user on the list, my outgoing messages get rejected as having an unverified sender address.  Although this is supposedly temporary, the user does not seem to get messages in a timely fashion.  Her ISP says that it a problem with SIMS.  Is there something I can do to fix this on my end?


Here is a sample reject header (I've changed the actual addresses.)

 Failed to deliver your message to <users-address>:
 SMTP: Address rejected by host
 Host '' says:
