Thanks for all the work on v5 - it’s looking great!
I’m having trouble installing v5 … the installer won’t proceed because the email check isn’t getting through but throws and error: Expected response code 354 but got code “554”, with message "554 5.5.1 Error: no valid recipients ".
It seems the installer is trying to send a message with an empty recipient, something the mail server dies not accept (and rightly so I’d say ).
Perhaps a recipient address should be added to the installer screen so a test email can be sent to an actual recipient?
Meanwhile I got it going. It turns out that the installer is trying to send a message to the “From” email address. However (in this case), the mail server needs SMTP AUTH: Recipient address rejected: SMTP AUTH is required for users under this sender domain. I got it going by temporarily relaxing the checks on the mail server so I’m updating my suggestion to:
Perhaps the installer can either try SMTP and if that fails SMTP AUTH (or the other way around) or there could be a tick box giving the installer the option to use SMTP AUTH. Not everyone has access to mail servers…
I was getting this same exact error and wanted to comment on what was causing mine.
My email server provider Mailcheap recently switched over their underlying mail system and I found out that in that process I lost my sender aliases. So the email I set in “From Address” was no longer linked up as an alias, but instead of seeing some sort of error about the sender address I was getting this 554 “no valid recipients” error. This was in V4 by the way.
Something to check on in case anyone else runs into this error.
