Never said it did, just that there is a known issue with some mail sending systems if the email address contains "non-standard" characters like a dash "-".stefanheisl wrote: ↑21 Dec 2022, 16:53You are right, this does not mean that TerraMaster has a bad and not optimized forum. Many forums on phpBB software also work and do not accept third-party formats.
phpBB forums have two methods of sending SMTP requests (emails), there is the inbuilt functionality which i know does not have an issue.
There is also the option to use an external SMTP server. It could be what Terrmaster have configured in which case it could be their fault.
I know phpBB forums quite well. I have managed various over the past 30 years, though only manage one now.
