Address in mailbox given [hostmaster@] does not comply with RFC 2822, 3.6.2.)

I been having this issue for a long time with setting up the smtp email account for notifications and (i know the settings are correct), asnd once hit the “send test email” button you receive this error message:

There was a problem sending email. Please review your settings.(Error: Address in mailbox given [hostmaster@] does not comply with RFC 2822, 3.6.2.).

I been looking on this for a very long time and I was thinking/hoping this was a bug that wold be addressed at some point and thus would automatically disappear but that doesn’t seem to be the case. Admitted I been procrastinating to do anything about until this point for the latter reasons I just wrote. But now I am enough feed up of it to take action on it and get it over with…

So anyone knows how to solve this issue?

I am running the latest version of Owncloud and just updated today.

Thanks a lot in advance.:+1::smiley:
