pop3 on ethernet

[beverage]

I recently moved into a new dorm @ college and am connected to the school ethernet, ever since I've been having problems with my pop3 email accounts. I can recieve emails with both of them, but can not send emails with either of them. Are there any settings that I need to change on my end, or is it some problem with the university's servers/firewalls can this be fixed, or am I just out of luck.

Most pop3 accounts will only let you access them if you are connected/logged onto their network. Receiving email is generally possible, but to prevent spam forwarding, they require you to be connected to their network directly to be able to send through them.

so am i out of luck while using the network?

Unless they have a dial-up connection you can dial into, otherwise yes, you're out of luck while at school.

Best case scenario is check and see if your ISP that you can't send through has a Webbased email system.

First off, POP is for receiving mail only, not sending. SMTP is used to send email. As Setral said most ISPs restrict access to their SMTP servers by IP, so if you're not using their IP block, you can't relay through them. There are a few solutions. 1) I'm sure your college has an smtp server you can use, just specify that in your MUA, this would be the easiest and fastest. 2) If for some reason you really want to use this SMTP server instead of your colleges, you can probably still access your old SMTP server via some type of SMTP authentication or POP B4 SMTP. Most IPS's offer one or the other.

Yet again, another reason why I stick to webmail. Yeah, hotmail is pretty crappy, but it is fricken awesome in someways

Let me summarize: You're not on your ISP's network so they don't let you use their SMTP (mail delivery server) server.

You do not, however, HAVE to use their SMTP server. Your school's SMTP server should deliver mail just fine, even when you're retrieving it from your POP mail accounts.

You might be able to get lucky and guess it. Try to ping "mail.schoolname.edu" (IE, mail.harvard.edu) and see if that response. If so, stick it in as your SMTP server and see if it works. Alternatively, tell us what school you're at and someone can probably figure it out pretty easily.

As a last option, call your school's Helpdesk and tell them you're setting up e-mail. Don't tell 'em it's an outside account or anything. Just tell them you need the IP address or domain name of their SMTP server.

Keep in mind that not all mail servers will allow you to send mail from an address not on the server. Your school's SMTP servers may not allow you@yourdomain.com as a reply address for you@school.edu. On the same note, some networks do not allow port 25 (SMTP) access outside of their networks as a spam control measure, so you MUST use your school address/SMTP server(s) or use web-based mail.

Another thing to keep in mind if you're not trying to use an ISP account is that mail servers may use IP authentication for their users. Check with your mail admin to make sure that your account has permissions to send from your current IP and/or request webmail access for sending.
