- If the emails are only account setup or forgot password related, I don't see much issue. If you send daily digests or chat recaps, perhaps it's a bit much to assume this responsibility. - 3CX has a footer in each email: This email was sent from an 3CX SMTP Relay Service. If you suspect the service has been used unlawfully and/or outside the scope of delivering 3CX Phone System related emails, please file an abuse report here: https://www.3cx.com/smtpabuse https://www.3cx.com/smtpabuse How much work this requires on their end to keep clean is unknown, but definitely a concern as well.
