Forum bug - Gmail auto-flags as spam, as not following proper bulk sender methods

[NiKiZe]

Indeed, normally gmail does not block by SPF - and it works for me as far as I know. But fixing SPF will at least avoid being classified as spam.

I do get curious about which other types of errors you have seen - since I manage a server that sends newsletters to many gmail accounts without issues, atleast after some fixing - but it was a long time ago.
