No. of email listeners
Hi there,
I have application which has to listen to 30 email accounts and create the cases when an email is received and below are few queries
1) What is the best practice on the no. of email listeners?
2) What would be the impact of performance of the system?
3) I foresee the increase of email listeners as new markets might get introduced and how can we tackle the problem? ( One straight solution is decrease the no. of email accounts)
Thanks,

The number of listeners should not be an issue. One Pega customer has 2000 and has seen no performance issues. The listeners run as threads and obtain locks on the mailbox. Therefore, it is probably better if they run on a single node - there is very limited benefit to multiple nodes. Node failure is one draw back to this, but as email listeners are more "polling" than "listening", node restart will perform catchup. Hope this helps.

I don't think the listener runs a thread. Each listener will have a corresponding requestor , so if a system 2000 listeners it means 2000 requestors. As the no. of requestors increase there will be performance issue until and unless we handle.

Hi Venkata,
1) What is the best practice on the no. of email listeners?
-As many email inboxes that many email listeners
2) What would be the impact of performance of the system?
-There shouldn't be performance impact as each listener monitors its own inbox
3) I foresee the increase of email listeners as new markets might get introduced and how can we tackle the problem? ( One straight solution is decrease the no. of email accounts)
I am not sure of the exact requirement but for each account you need a folder(inbox) to store the mails.
