Hi,
I am hoping for some advice on how to proceed to resolve the following incoming mail issue.
Ordinarily transactions come in like this and are handled perfectly
however for some the negotiation looks like this
the difference here is the remote server is compounding the mail from and rcpt to transactions into a single transaction and when this happens Indy never responds to the transaction and the thread hangs until it is cleaned up several minutes later.
Unfortunately several domains including the microsoft domains do this and for me this constitutes a very large number of messages.
I am hoping someone can advise a way to work around this issue.
Thanks for any guidance,
-Allen
I experienced the issue above with PIPELINING set to true. Changing that to false causes everything to function as expected.
I guess that answers my question, sorry for the silly question, unless there is something I ought to have done to enable pipeling to function properly.
