I can see in my email that Kashif responded to this. However, the thread appears to have disappeared. :-o
"The server committed a
protocol violation. The server response was: Enter mail, end with "."
on a line by itself'."
On a
different SMTP host in the same network, running the code works just
fine.
I've written some test code, which is in the attached file
TestAsposeEmail.zip
(I took the license files out).
This program outputted a couple log files, which are attached in
testAsposeEmailLogs
24-04-2017.zip
The file SmtpTest.log contains the actual exception thrown by the
"offending" system.
The
file called Aspose.Email.SMTP_2017-4-24.log is a text file that echos the SMTP
dialogs. The first half is the dialog as conducted by the system on which the
dialog fails (10.13.10.60); the second part (172.16.4.83) is the working
system.
What puzzles me is what would trigger the protocol violation exception in the
first dialog - I don't see anything wrong there.
Kashif then responded the same day, as follows:
I
have tested this issue using my test account credentials and observed no issue.
It seems to be specific issue with your server settings. I have shared the log
files with my product team and will write back here as soon as some feedback is
received.
I'm not amazed that you could not replicate this, as I myself have been unable to replicate the behaviour here. I would be interested to know what specific situation or setting could cause this behaviour to occur, as the SMTP dialog itself, including the response that the server coughs up, seems to be perfectly valid.
