hi,
finally found the problem with outlook express and AUTH LOGIN, it
appears that Outlook Express requires the prompts of:
Username:
Password:
as exim is currently parsing the config files server_prompts in
plaintext.c using a colon as a string separator then it will be unable to
send these required prompts, rather than giving out a sensible error
message outlook just sends carraige returns and quits.
changing the colon to another parse symbol would allow outlook to work,
or maybe a way of escaping the colons in the config file? something like
this maybe for outlook:
asmtp_login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username\: : Password\:"
Thanks
Paul Kelly
