Re: The external mails are slow

Maybe greylist works?
Check mail.log ..
There can be a record as:
Jul 25 12:08:43 mymailserver postfix/smtpd[10064]: NOQUEUE: reject: RCPT from unknown[119.30.3
8.61]: 451 4.7.1 <internal@mail.addr>: Recipient address rejected: Intentional policy rejec

Re: The external mails are slow

As @zh mentioned, it's caused by greylisting service. For more details, check this tutorial:
