E-mail - SMTP
Q: What is the FCOB outgoing e-mail (SMTP) server name?
A: smtp.cob.ohio-state.edu
Q: Are outgoing e-mail (SMTP) connections restricted from within the FCOB network?
A: Yes. Due to the evolving nature of e-mail viruses and spam threats, we have been forced to restrict outgoing SMTP connections from within the Fisher fixed and wireless networks to only the following SMTP servers:
- Fisher SMTP server: smtp.cob.ohio-state.edu
- OSU SMTP server: smtp.service.ohio-state.edu
Q: Are there any other restrictions on SMTP connections?
A: Yes. The following limitations are in effect for mail going through the FCOB SMTP server:
- Maximum number of e-mail recipients: 150
- Maximum message size (including attachments): 15 MB
Q: I receive an error message when I try to send e-mail through the FCOB SMTP server from off-campus.
A: In order to prevent unauthorized users from sending unsolicited commercial email (commonly referred to as spam ) through their SMTP servers, network providers have been forced to block such requests when coming from other network providers (called open relaying ). The dangers of leaving an email server as an open relay include security matters and the easy facilitation of email spam and viruses. Although closing our email servers will not halt all spam and viruses, taken together with other steps and special measures, it will help to greatly reduce these security concerns and annoyances.
The Fisher College of Business has followed suit with this practice. Therefore if you need to send mail using your FCOB e-mail account ( lastname_#@fisher.osu.edu ) from outside of the FCOB fixed or wireless networks, you will need to use the outgoing e-mail (SMTP) server provided by your local Internet service provider. The OSU Office of Information Technology (OIT) has also decided to make OSU's central email system "closed" and not allow open relaying from other Internet Service Providers.
This will not affect you if you are sending email from your office or a FCOB computer lab, nor will it affect normal delivery of your FCOB email from others abroad.
You must reconfigure your e-mail client application to use your Internet Service Provider's outgoing email server. A comprehensive list of SMTP servers for common Internet Service Providers is provided by OIT Enterprise Networking. If you cannot find the proper outgoing SMTP server for your Internet Service Provider, please contact the help center of your particular Internet Service Provider for assistance.
