I finally got around to setting up my Outlook Express with my eircom.net address. I put mail.eircom.net as my incoming and smtp.irishbroadband.ie as my outgoing server. I am receiving all my incoming mails but i can't send any. I just keep getting errors.
Any suggestions as to how i can fix this problem would be appreciated.
I'm sorry I don't know anything about settings for eircom but I expect your outgoing smtpserver should be still eircom.net rather than irishbroadband. There's something listening on port 25 on smtp.eircom.net - maybe you could try that or mail.eircom.net also.
POP3 only applies to incoming mail. The OP is receiving their incoming mail so there isn't a problem with POP3 configuration. The problem is with SMTP (outbound e-mail).
I had a similar problem and it was solved by using a different SMTP server than the one given by Irish Broadband. I found the correct name on their website but it was certainly the case that the name given in the setup document was incorrect.
Sorry, since switched to Perlico broadband so don't have correct address to hand
