Topic: cannot receive mail from outside, SMTP error

[Renan Nepomuceno]

To All,

     Good day to all, I am having a problem with may mail. Right now I upgrade my SME 5.5 server to 5.6, after the update I am no longer receiving mail from outside. I can receive and send mail from inside but from outside I cannot, even I try to telnet like this e.g. telnet xxx.xxx.xx.xxx 25 from outside using public ip address I cannot but on my local network I can do that (using of course my private ip). When I try to telnet from outside I always receive like this:

 "421 SMTP service not available, closing transmission channel"

 without a quote but from inside I don't receive that.
Even I update the smtpmailfront to e-smith-mailfront-1.0.0-01rbl.noarch.rpm  the problem is still same.

Can anyone help me

best regards,
renan

Do you have it set up as a public server/gateway?

Bill,


     Yes I setup it up as a public server/gateway but before I upgrade my SME 5.5 server to 5.6 it is working. I just only upgrade it because I want tou use an rbl sites to block spam because I want to use my trendmicro interscan viruswall so that mail can be scanned likewise checking for spam mails in one PC.
    I don't like to use spamassasin, tmda and spam bouncer because it is very annoying to all users.

     
Best regards,
