Re: Re: How to pass authentication through Mail::Sendmail

The problem is related to authentication. If I would send an email to a person inside the network it will work OK because authentication is not required their but the moment I want to relay outside the network authentication is required and the user and password is checked to send email. If you look at email programs : outlook, eudora, they all provide an option to allow authentication when sending email and this is in most cases the user and password which is also used to check email.
Note : If I use an SMTP server which is configured not to require authentication which nowadays you don't find anymore because nobody want allow anymore non-authorized people to use their SMTP server to send email because most people used non-secured SMTP servers for spamming purposes

Greetings. It may be related to authentication, but... Authentication has not been part of (E)SMTP for a long time - an AUTH extension has been kicking around for a couple of years and sendmail has support for it starting from 8.10 (based on SASL). Other than that, some authentication has been provided through a hack called pop_before_smtp (similar to what you refer to). The short story is: You have to find out which method your site is using - $Mail::Sendmail::log may be helping you here; I doubt very much that Mail::Sendmail has support for either ESMTP AUTH or POP_BEFORE_SMTP, and that means you may have to roll your own (might be hard); Perhaps you can charm the postmaster to carve a hole in the relay rules, wide enough for your script to peep through - but don't count too much on it.
