We just went through a week worth of testing before moving this server into production, and didn't see delays sending for a week.
Now we have moved it into production and mails are being delayed 4-6 hours.

Could someone help us figure out what is going on?

Thanks.

Re: 4-6 Hour delay in sending mail

We are at a complete loss on what could be going on if anyone has an idea of what to check/change it would be greatly appreciated. I've tried to attached my mail.log and copy/paste it into the text of this reply without any luck.

Below is the main.cf if there are any other logfiles that will help i will be glad to upload them.

Thanks

Try removing "check_policy_service inet:127.0.0.1:10031" in smtpd_recipient_restrictions, and comment out smtpd_end_of_data_restrictions. Then restart Postfix to see whether it happens again or not.

Re: 4-6 Hour delay in sending mail

Thanks.

The problem is resolved. The network card in box had started to fail.
