This wonderful explanation about using multiple smtp servers is great, but leaves out one very important detail: if a user is using multiple smtp servers, what about the different authentication credentials for each one? The explanation given although addressed to multi smtp servers does not cover that aspect.
Anyone know how to use multi authentication with multi servers?
Did that work for you. Because I think how can the UserName be same for different SMTP Servers. At least password can be same but how can the UserName. Suppose If I set three domains smtp.domainname1.com:25, smtp.domainname2.com:25 and smtp.domainname3.com:25 then User Name of three SMTPs canβt be same.
