So I suppose it's working like it's supposed to. I guess my only other option is to turn off smtp_skip_5xx_greeting, in which case it will hand off to mailer2 on the first failure, correct? Is there any option to configure the number of failed attempts before handing off to the fallback relay, other than just ON/OFF? Thx, SteveJ
