I am not sure if this is workaround. I am afraid, that it can mean that SMTP communication is reset every 1-2 minutes. It will work if you have not too many and shorter e-mails. The impact will be mostly on large e-mails and with higher traffic.
The error is easily reproducable. I have the same situation in my virtual test enviromnet and on the physical servers, so it does not look like anything rare.
