Mail log entries?

[ctroyp]

Could anyone enlighten me as to what happened to cause these entries? Is it spam that was rejected or something of the sort?

This is because of a missing file (/etc/postfix/ssl/cacert.pem), but it's only a warning, nothing serious.

There someone tried to send emails over your server; might be a spammer, but as you can see he wasn't successful...

Cool! Its nice to see the defense in action.

I had a similar entry that was showing that an email was blocked that I actually sent from another one of my email accounts (not hosted from my server). Where do I configure to allow access for this account? FYI, it is an identical error as the one I posted above, but with a known sender that I want to allow.

If you're sending with an email client, just enter your ISPConfig server as SMTP server, and use a username and password from your ISPConfig box.

I must have explained wrong...I am trying to send an email to this account using a yahoo account. The email doesn't come in the this account and it does not get kicked back to my yahoo account (which tells me it went somewhere). By the way, I am using UebiMiau to access the mail hosted from my server.

The mail from Yahoo should arrive without problems, unless the MX record for your domain is pointing to some other server. I'd check that ASAP.
Do you see anything in your mail logs when sending an email from Yahoo?
