Hi,
We have a scheduled maintenance for around 8 to 10 hours for our
Mail storage servers. During the downtime, we plan to HOLD all incoming
mails and release them once the storage servers are up. To our existing
smtpd restrictions, We added smtpd_end_of_data_restrictions and it
worked. (postfix version 2.8.7)
smtpd_end_of_data_restrictions = check_client_access static:HOLD
The total size of mails is expected to be around 200 to 300 GB. My
concern here is; will too many mails in HOLD queue, impact the
performance? Is it the right way to handle this use-case?
Regards,
Clement
