If you use ipv6, use an ip4 special transport for google they simply have problems with ipv6 i.e like this http://tanguy.ortolo.eu/blog/article109/google-ipv6-smtp-restrictions dont forget include your ipv6 address in spf for domain and mailhost prefer TXT before SPF record, or have both matching additional check mailhost A/PTR/HELO matching 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
