Can't send mail from inside Jails.

[Nulani]

I can't send mail from inside Jails. It also affects forums, such as phpBB. They can't send notices - which is how I noticed the problem in the first place. I haven't made any changes to the default setup as far as mail is concerned.

Any suggestions on what might be wrong and how to fix it?

I can't seem to send e-mail even on the host system and not even locally.


ginnungagap# mail -s Test root

ginnungagap# mail
No mail for root

if you want to send emails locally, you have to enable some MTA in your jails. The easiest way would be to add sendmail_enable="NO" into /etc/rc.conf in the jail...

and as the outgoing mail problems, you should check /var/log/maillong and see what's going on there. You need to be more specific to get some help here.

It seems like it continuously times out. I can ping the destination and I've tried several others.

Edit: It times out most of the time. One or two of fifteen sent e-mails did get through.

I've figured out what it is. Is there a way to tell Sendmail it needs to relay all e-mail to my ISP's SMTP?

[Nulani]

Would * smtp: smtp.isp.tld in /etc/mail/mailertable followed by makemap hash /etc/mail/mailertable < /etc/mail/mailertable do the trick?

search for Smart Relay on google.

I already had. They all ignore:

################################################## ####################
#####
##### DO NOT EDIT THIS FILE! Only edit the source .mc file.
#####
################################################## ####################

though, which is why I thought I'd ask.

I take it it is safe to do so? I changed the 'Smart' relay host entry to DSsmtp.isp.tld and it's all working now.
