Indeed it was a hotmail account, so I changed it to one my gmail account and seems to be working again.
I suspected as much, and I am glad it is working
Adding babajeliro to my safe list but that didn't work.
Yeah, that was a long shot suggestion. Thank you for trying anyway.
Which begs the question why does phpbb spoof email addresses if it just causes problems?
Because smaller boards sometimes don't have dedicated addresses to send emails from, and any email needs a value in the "from" field. In short, it is a hack that works better than any alternative, but one that could easily be avoided if Golly changed the email to something like registrations_at_shipbucket.com.
