Need help for allowing bulk mails in zimbra

Post by krishnachaturvedula »

Hi,

We have a application that sends bulk mails at a time (approx 500). We found below issues

1) Zimbra is blocking mails with 421 error. Seems like it is blocking mails more than 100. We need to requeue all mails manually
2) Also observed that a set of mails are delivered and rest set delivered after 1 hr exactly (3600s).

Need help in below:

1) Need to config zimbra to allow all mails.
2) If there is any block for 3600s, need to allow all of them

Thanks,

Krishna
