sendmail connection timeout
 

Hi

About A week ago I was a 1 year happy user of sendmail at home.
I have SBC/YAHOO DSL. Sudennly I got connection time out for
all my external mail. Does anyone of you know if Yahoo/SBC blocked
port 25?. Is there any way to baypass?

you should ask them.

I know this is an old thread, but I had the same problem just recently.

I did not ask if SBC/Yahoo blocks port 25, but I did get the system to send mail to external addresses by editing the "smarthost" line in the sendmail configuration.

I managed to find out the smtp server (for me at least) is smtp.prodigy.net. Modifying the appropriate line in /etc/mail/sendmail.mc made everything work again.

This was on an FC4 machine, and the exact steps were;
1. Uncomment the line in /etc/mail/sendmail.mc (by removing the dnl from the front of the line)
2. Replacing "smtp.your.provider" with "smtp.prodigy.net"
3. running "make -C /etc/mail"
4. restarting sendmail with "/etc/rc.d/init.d/sendmail restart"

Just giving the solution in case anyone else might need the answer and comes across this post.
