I need to send out a mail with attachments to like 4000 users. If i copy and paste all the email addresses (separated by commas) and try to send it, will zimbra be able to send it?
Does the zimbra internal breaks downs the emails and send batch by batch? Domain by domain? (a lot of addresses are from hotmail and some gmail)
Need some insight to this if possible.
We will break the addresses down and send one at a time. In general you should use a distro list for this. We also at some point could add a bulk send but there are many ways to script a send to a large number of users. Your much better off sending in smaller batches so you don't swarm the system with lots of mail at the same time. It should handle it but better to have a little pause or two between large message submits.
