Cant send Outgoing mail with Netsource DSL

Anyone have any ideas? Would i be better off with trying to find a public smtp server or is there any workaround with this?

Tks

Are you using their SMTP server?
What error are you getting?

Hi,

Im using my eircom.net account through netsources dsl. Its going out on port 25. Is the port closed off on eircom's side or netsources side?

I can receive but cant send mails

An ISP wouldn't close off port 25. Can you telnet to mail1.eircom.net on port 25?
You should be able to send mail through mail1.eircom.net once you POP your mail first.
What error are you getting though?

outgoing mail server = mail.netsource.ie

The Eircom one should work too.

Quick FYI guys:
No ISP allows other ISPs customers to relay through their SMTP servers ... it's effectively because there's no real way for the smtp server to authenticate you.
In contrast, an ISP allows you to send mail as anyone you like - so in this case netsource allows you to send as myusername@eircom.net, but eircom.net won't because you're connected through netsource.

An SMTP conversation would look like :
telnet mail.eircom.net 25
Trying 159.134.198.135...
Connected to mail1.eircom.net (159.134.198.135).
Escape character is '^]'.
220 mail02.svc.cra.dublin.eircom.net ESMTP
mail from: myuserid@eircom.net
250 ok
rcpt to: pron@notreally.boards.ie
553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1)

See - I don't just appear on Netsource threads (oh ... wait ....:) )

Eircom use POP authentication on their SMTP servers, so in theory it should work. I connect via IOL and can use my Eircom account no problem, once I pop my mail first.

Ditto for me (on Netsource).

Besides the pop before sending, you could password protect the SMTP servers, like Yahoo do.
