Exim Mail Sending Issue

[sambugtreat]

Before 10 days we were experienced a spam email attack in whcih using our mail server spammer has sent millions of mails
which exceeded our daily quota and all my emails went to queue by getting adviced from professionals we deleted all the email
which were in queue by SSH commands by today it was completed we again started our exim and try to send email through our contact forms and request quote
but there was no email sent till now when i reached to for mail delivery reports in WHM is stated that "No route to host"
"retry time not reached for any host after a long failure period" ,"retry timeout exceeded" liek this report i was able to read



Its urgent i ll be happy if any one answer my post as soon as possible

Hello

Could you provide a specific example (without real domain names) of the message delivery failure message or output from /var/log/exim_mainlog? Is this happening when sending out to all remote mail servers?

Thank you.
