Clamd SMTP 451

[desarrollo33]

I own a server running 2 websites.

I can't send or receive emails, give me this message:

Code: Select all

Error SMTP: [451] Temporary local problem - please try later

When i comment etc/exim/exim.conf

Code: Select all

#CLAMD = yes

then i can send and receive, but the emails are spam, and I don't think it's very good to remove this antivirus.

I try to update clamd

Code: Select all

yum update clamav

and

Code: Select all

freshclam

Also try update the host for each web domain, for the ssl

Code: Select all

v-update-host-certificate user domain

Any idea?

I do this for each website

Code: Select all

v-update-host-certificate user user_web_domain

But the mail still spam and in thunderbird says certificate is not secure

In this test (https://www.checktls.com/TestReceiver) give me this:

Code: Select all

Cert Hostname DOES NOT VERIFY (mail.website.com != website.com | DNS:website.com | DNS:website.com)
So email is encrypted but the host is not verified
