Hi, Steffen, The ease with which this can be done may depend on which SMTP server your provider is using. The most common request has been for Microsoft's Exchange server which may be set to its extended SMTP mode requiring encoded authentication. The following patch should work for that server (watch for line wrap): system/schemes/smtp/handler/open-check: [none "220" ["EHLO" system/network/host] "250" "AUTH LOGIN" "334" [port/user] "334" [port/pass] "235"] system/schemes/smtp/user: copy enbase/base myusername 64 system/schemes/smtp/pass: copy enbase/base mypassword 64 ; which myusername and mypassword are set appropriately This method alters the current running copy of the protocol scheme that manages the SMTP connection. It tests with the extended HELO command, "EHLO", for the extended SMTP command set. Exchange frequently uses the "AUTH LOGIN" for encoded authentication. The script looks for this option and then offers the base 64 encoded version of the username and password. E-mail is then sent using the standard 'SEND command. However, there is no standardization of extended SMTP, and so many varieties exists. In theory, there is a work around for many or most; however, the list ran into one 3 months back that used a variety of SSL that did not have an "easy" work around. If the above script fragment does not work, there is a way for you to find out more about your SMTP server, if you are adventurous and you have the TELNET client software (most machines do). Let us know what you find. --Scott Jones
