I have a user who is experiencing problems sending to a particular domain. My logs show what seems to be a communication error between my server and the remote server. I have not experienced this type of error before. Is someone able to shed some light on this and give me an idea if this is my issue or the remote mail server's. My customer tells me he can send to the remote address fine from hotmail & yahoo. Below is a snippet from the log showing the error. Thanks.
This is one that Ipswitch would have to answer, as it is something new. But I can make a guessL
20040419 085939 127.0.0.1 SMTP (0A3462E9) >DATA
20040419 085939 127.0.0.1 SMTP (0A3462E9) 354 Start mail input; end with <CRLF>.<CRLF>
20040419 085941 127.0.0.1 SMTP (0A3462E9) [E] didn't send "/goAAP8KAAAACwAAAQsAAAILAAAZCwAAGgsAABsLAAAcCwAAKwsAACwLAAAtCwAALgsAAC8LAAAy
": connection reset
20040419 085941 127.0.0.1 SMTP (0A3462E9) [X] send error 4294967295 != 78
From a programming standpoint, 4294967295 is equal to -1, which happens to be the code used for a "SOCKET_ERROR". It sounds like the last log file entry there is occurring because IMail expected to get a result of 78 (because it sent 78 bytes), but it got back a -1. My guess is that the connection was terminated on the remote end, but in a way that IMail didn't handle it as it normally should have, resulting in that odd error message.
But, the "SOCKET_ERROR" response from the send() command could occur for many different reasons.
20040419 085941 127.0.0.1 SMTP (0A3462E9) [E] didn't send ". ": connection reset
This, however, supports the theory that their mailserver is terminating the connection.
