If I set timeout out fairly low say 10 seconds and add a large attachment say 4MB. It will sometimes generate a timeout exception. However the email will still arrive at it’s destination.
This was fairly easy to reproduce if using a large attachment and low timeout but still long enough for it to send. Setting timeout very high won’t reproduce it. I could perhaps reproduce it 30% of the time.
I have no server details to share as this was done on Office 365 so you can just use own account.
I suggest you keep setting the timeout lower by 1 second increments until the time taken to send the email is as close as possible to the timeout. I don’t know the average time of sending an email. I sent a 4MB attachment with a 10 second timeout. So it sounds like your environment is quicker so I would reduce the timeout. If the 10 seconds is plenty then it won’t replicate the problem.
Hi, any news on EMAILNET-34953?
