Local traffic should go via our internal smtp gateway (anonymous, unencrypted) (say internal.net), but external traffic should go via a TLS-encrypted smtp server using a specified username and password (say secure.net). Ideally we'd also like to replace the message body of any email going to an external destination other than secure.net with a simple link or general text. > > To make this work I've set up anonymous relaying from the local network (works OK) and also added entries to the smtpfwd.tab file (this doesn't cover other external addresses but I want to get the basics working first): > > "internal.net" "smtp.internal.net" > "secure.net" "smtp.secure.net:587,NeedTLS=1" > > However I don't think I can put the authentication details in this file, so I've created another file \userauth\smtp\smtp.secure.net.tab with the following entries: > > "LOGIN" "myusername" "437687234219932" > > (with tabs beween quoted entries) > > Note that I've also tried replacing "LOGIN" with "PLAIN".

The usual error is Client not authenticated, but trying different settings I've also had authorization method errors. I've checked the password and can send mail via secure.net if I use my mail client (unencrypted) routing through a local stunnel daemon rather than xmail. > > Have I got the settings corrent? What else can I do to make this work? There are two ways to talk TLS in the SMTP world. SMTPS, which is TLS since time zero, or STARTTLS which starts in clear and then uses STARTTLS to switch to TLS. I noticed that XMail at the moment does not support the former, which I will add for 1.28. - Davide _______________________________________________ xmail mailing list [email protected] http://xmailserver.org/mailman/listinfo/xmail
