Hello,

I've configured my sendmail on a RH7.3 but when I try to send a mail with mailto this is the error report that I receive. Does anyone can give me some answers.

The first eight errors look like sendmail is being started in daemon mode (-bd) multiple times, which won't work. This is separate from not being able to use mailto, though.

The last two errors look like you were able to DNS the MX records for the recipient's address, but weren't able to make an SMTP connection to these servers. Make sure iptables is not blocking outbound TCP port 25 traffic. Also, your ISP may be blocking outbound TCP port 25 traffic, too. They like to do that nowadays to make life miserable.

So I assume that he should not run in deamon mode. How can I change that? Do you now a sollution for that.

I is possible that my ISP is blocking the SMTP port. They are blocking everything below 1024. But if I send a email with a other program (outlook) does he then make a SMTP connection.
Is there a work around for that problem.

Regards

daemon mode is fine to use, but there is something wrong with it if it is creating these errors. Outlook will work because it's probably configured to use the SMTP server that you're ISP provides, which is allowed. What's no allowed (potentially) is connecting out directly to the servers, which is what sendmail is designed to do.

To get around this, you can configure sendmail to connect to your isp for the delivery of all non-local mail. This is called SMART_HOST
