450,000 queued Mails in 5 days

[PryosCode]

I am using this Mail Server for a while now. Everything worked great, but 5 days ago it suddenly queued 50,000 Mails to “system@localhost“. And I see this spamming the live feed:

‌

21:57:28 12-A1F7-CBE06299ECCB... 127.0.0.1 → 25 fcrdns relay: acl guard helo: mail.pryos.xyz spf tls: ECDHE-RSA-AES128-GCM-SHA256 mail_from: <> rcpt_database rcpt_to: system@localhost bounce dkim clamd privacy Message Queued (981A0D26-DC54-4412-A1F7-CBE06299ECCB.1)

‌

‌

It won’t stop and I just can’t understand why it just suddenly started. I haven’t changed anything. Now the server has queued over 450,000 Mails.

‌

Thanks in advance!

Hi @PryosCode , I’m having the same problem. What did you do to solve the problem?

@clemens fait I have used an invalid email address for the alerts (System settings > Configuration > Email to send alerts). I just had to change it to a valid one and after that everything worked just fine.
