Hi,

some of my mail account users recently noticed while using public WLANs
in hotels or something, that port 25 is either entirely blocked or
redirected to another MTA (to which they don't want to give their
mails). I think WLAN providers do that to block spammers abusing open
mail relays or spam bot networks.

To provide our mail service to these networks we thought about doing
some ugly VPN tricks, we thought about more ugly web mailers... but I
would like the much simpler way to accept SMTP via SSL at 465 in the
hope, that neither open servers nor infected boxes offer encrypted spam
relay. So what's your experience, is this a port that is treated same
as port 25 or is there in general a better chance for this?

Thanks in advance and kind regards,
 Frank.
