I am working on a "beta" website that uses Sitefinity Community Edition 3.x, before commiting the client to purchasing the product.
We seem to have a problem in that the newsletters module will only send to a maximum of 100 subscribers for each newsletter. Then it hangs.
If the number of subscribers is less than 100 it succeeds every time.
We have adapted the time limit between each email to 1500 miliseconds. All email addresses are valid. And there is a non null and non zero length first name and last name for all records.
The limit of 100 is an estimate, calculated using:
1. All subscriber lists smaller than 100 send fine.
2. Using the % that shows when the send newsletter hangs, we have calculated that it hangs anywhere between 104 and 118 subscribers. Ie:
200 Subscribers hangs at 58%, ie, 118.
340 Subscribers hangs at 32%, ie, 108.
436 Subscribers hangs at 24%, ie, 104.
597 Subscribers hangs at 19%, ie, 113.
303 Subscribers hangs at 39%, ie, 118.
74 Subscribers succeeds
88 Subscribers succeeds
70 Subscribers succeeds
So much for the symptoms. My questions are:
a. Is there a limit on the amount of subscribers for the community edition
b. Could this just be a queueing problem on the mail server, ie, if I incease the time between each email being sent, is that likely to solve the issue?
c. Any other suggestion?
d. Has anyone else experienced this with the Community Edition?
e. Would it be any better using Sitefinity 3.7 SP4?
