Hi,
We frequently have to create relay rules to remote smtp servers using username and password. Before we create the confguration, we always check the availability of the remote server and port and we also try to check if the provided username and password are valid. For this we are using openssl and curl but both are unreliable because both can report false positive and false negative results. I'm wondering how others would do this. Is there a similar tool to check smtp auth like 'smtp-source' for stress testing? Or everyone has to come up with their own solution? Any idea is appreciated! JSjr
