Email clients from outside PIX

[mahesh_kudva]

I have a mail server running on the inside interface of the PIX 515E firewall. I have SMTP authentication. All users on the local network can easily have SMTP authentication but users who use their clients like Outlook Express, from the external world cannot do SMTP authentication. But POP works fine.

Any suggestions ??

Thanks

A likely cause of this problem could be that the external networks where the remote users are located are blocking outbound smtp access. If the networks where these users are located are not under your control, I would expect this to be the case.

If this is the case, a solution would be to have the outlook express clients reconfigure the smtp server setting to use the smtp server on the external network.
