I have developed a dis attended windows service(services that runs in background) to send thousands of emails trough an Exchange Server. I'm using the following account to send emails
For some reason, our customers tell us that they never received the email(at least 25 customers complains about this). Because we send thousands of email we couldn't use an Outlook client to read the Inbox. I was thinking in use EWS. Whe use
.net SMT client to send emails in Async way. But let's think in the following scenario:
I send an email today, and for some reason (network bottleneck) this messages holds on the Exchange and couldn'be dispatched three days after.
Because our Windows services runs in background we can't catch this errors. The only way is try to read some notifications sents to the sender address(
firstname.lastname@example.org in my case). How can I figure out this situation?
