Hello,
I installed DocSpace community edition using the provided script, and it works. However, password reset emails are not being sent, nor are invitations to new users. Curiously, however, account verification emails are being sent, as well as the SMTP test email, that also got delivered alright.
When trying to set a new password, the following appears in the logs:
==> access.log <==

and on the mailserver (port 25, no auth, the IP is whitelisted as permitted
client), I see the following:

This includes debugging output between the EHLO response, and the client
(OnlyOffice) just sending QUIT.
I verified that the test SMTP email arrives, and I was able to verify the
admin/owner email address. test emails still work, but new user invitations
and password resets yield the above premature end of the SMTP dialog.
Any idea what could be going on?
Thanks,
Martin
Update: The SMTP session works and emails are sent if I switch from port 25 to 587+SSL and provide authentication information, i.e. use submission instead of plain SMTP.
