Hi, zilog
I had long discussion with JCOM (ISP), this morning.
JCOM said they have been managed SMTP and SMTPa server long long time, and both servers are normally operated.
JCOM advised me, pls ask you if there is unexpected problem in Avast smtp settings area, does your Email alerts system support port 465?
I don't know the scheme of access into external smtp(a) server from the Avast Email Alerts.
