Hello All,
I have a mail server (postfix 2.2.10, Devecot, IMSS/SPS 7.0).I noticed recently that some emails are delivered with very late (some hours, one or 2 days) even if the emails are sent from a local domain user to a local domain user.
In the mailq, i can see the bounced emails with the error (delivery temporarily suspended: unknown mail transport error).
Is there any idea that can help? Thank you in advance. Rachid
