Hello friends,
Previously I had posted the same query about the timed out issue I was facing in the email event when I was trying to send the mail to 200+ users. The work around I had done was working fine. But this time since user is trying to send mails to more users that is 1300+,again I had this issue.
So this time work around I did was, batching the mail id's before move to the mailaddress collection, which need to be done in the email event code level.
i.e sending mails to 200 users in a batch, so that smtp server will be congestion free.
