Hi Stan it was not about ptr matching A Record , it was about matching helo to ptr/A, i.e. A/ptr = mail.example.com but helo = smtp.example.com and it was about ,this was classified by some hosting provider ( using v4bl.org RBL helo mismatch results ) , as a customer "ban warning" which is simply nonsense, but for sure it is best to have all parameters matching ( dont kown why this is/was/cannot be done in this case ) Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
