Hi

Thanks for the feedback. I double checked my logs and noticed that BATV mail tagged with prvs= is being handled correctly. And callouts succeeding.

The problem is limited to mails tagged with BTV1==. Log details below, email addresses removed of course

2010-11-03 13:59:13 H=mcsdspam02.muscogee.k12.ga.us [96.38.231.248] F=<btv1==9238326409d==EMAIL> rejected RCPT <EMAIL>: Sender verify failed

I manually checked and the email address in this instance does exist.

Regards
Leon Liebenberg

There should be no problem with Exim's callback feature because Exim
uses the BATV signed e-mail address for callback.

So, please show us some logs.

IMHO only callback in combination with greylisting is a serious problem.

Please consider that BATV tags are not standardized by now:
