Port: 110
Outgoing Server (SMTP): mail1.eircom.net.
Port: 25
Username: Input your email address
Password: Input your password.

You might want to consider a more permanent email address. Carrier
provided email addresses are subject to change due to mergers &
acquisitions.  gmail, yahoo, etc are more permanent; but you can also get
your own domain and pay a provider such as LuxSci.com to host your email
servers which would avoid this sort of problem.

Are you running your own server locally?  Many dynamic IP address blocks
are blocked "just because" they tend to be sources of spam this way. Port
25 from a dynamic address is a spamhaus favorite to block.

Can you provide you settings?  Hard to offer help without the facts...
