My server is only for hosting KeyHelp with user only me,
but now it seems trying to send email which I didnt try to. /var/log/mail.log show these :
Feb 25 16:57:24 server postfix/smtp[3870]: connect to veloxzone.com.br[200.223.8.81]:25: Connection timed out
Feb 25 16:57:24 server postfix/smtp[3870]: B29DEFAFCD: to=<zfixhapke1975@veloxzone.com.br>, relay=none, delay=65466, delays=65462/0.13/4.2/0, dsn=4.4.1, status=deferred (connect to veloxzone.com.br[200.223.8.81]:25: Connection timed out)
Is my server trying to send unsolicited email? Has my Mail server been hacked?
That quote from earlier post was from the /var/log/mail.log and there was a mail queue which I never intend to send. I have delete it since.
I am afraid it can happen again.
