POP3/SMTP Questions


Hey folks... some help would be nice if possible here. I'm running sendmail for SMTP & Qpopper for POP3. Here is the dilema... from my commad prompt.. I'm able to send mail to any email address but when I use outlook express I can only send mail to users on my network. other wise I get error 550 relaying denied... any ideas why? Secondly, I can receive mail from users on my network no problems but when I test email myself using my yahoo account, I will sometimes receive a message and sometimes not... I'd like to know what the heck is this inconsistency??

Thanks to anyone who could help me out on this one!

Chris

Replying to Myself

well I've figured how to fix the error 550 relaying denied. added the line "FEATURE(promiscuous_relay) dnl" in the sendmial.mc then rebuilt the sendmail.cf file with the m4 command. This option is not appearantly the safest as I get a warining when restarting sendmail. Sendmail kindly lets me know that my SMTP server could be misued by spammers. I still haven't figured out why I can only sometimes receive mail from other domains other than my own but if someone has any ideas, it would be nice to hear them. Basically my POP3 problem is that users on my LAN can send mail to each others no problem but when hotmail or yahoo sends mail to my POP3 server, it doesn't always come through for some reason.

ciao!

Sendmail defaults to a no-relay configuration.

Have a look at http://www.sendmail.org/tips/relaying.html for options, especially the roaming users link.
