Yes, I fixed that in the guide examples, thanks for noticing!

So there is already something running on your listen port, netstat and ps might 
help.

Sounds like you killed not everything :)

Snapshot of OpenBSD or snapshot of OpenSMTPD? 
Which package of opensmtpd-extras? 

You need the latest snapshot tarball or latest -current opensmtpd-extras 
package for it as well.
Otherwise filters will not work, because path for loading them has changed 
recently.

If you need hints what is going wrong start with debug/verbose mode, e.g.: 
smtpd -dv

Re: Spot of bother with send to lmtp

[Steve Conrad]

To clarify, I'm running the OpenBSD snapshot, which gives me 
opensmtpd-extras-201601122027

The port is not blocked until I start smtpd, so the filters must be blocking 
the port:

# netstat -a |grep smtp
# ps ax |grep smtpd
# smtpd -f /etc/mail/smtpd.conf.vmail
# netstat -a |grep smtp 
# ps ax |grep smtpd 


The log file now shows smtpd complaining about a blocked port:

Feb 3 13:30:55 frisco smtpd[9904]: info: OpenSMTPD master starting
Feb 3 13:30:55 frisco smtpd[13480]: fatal: smtpd: bind: Address already in use
Feb 3 13:30:55 frisco smtpd[11018]: warn: lost child: pony express exited 
abnormally
Feb 3 13:30:55 frisco smtpd[26800]: warn: lka -> pony: pipe closed
Feb 3 13:30:55 frisco smtpd[6696]: info: queue handler exiting
Feb 3 13:30:55 frisco smtpd[12051]: warn: control -> pony: pipe closed
Feb 3 13:30:55 frisco smtpd[10800]: info: scheduler handler exiting
Feb 3 13:30:55 frisco smtpd[16739]: warn: ca -> control: pipe closed
Feb 3 13:30:55 frisco smtpd[11018]: warn: parent terminating

The version of smtpd in the OpenBSD snapshot declines to share its version 
number:

# smtpd -h
version: OpenSMTPD master

So is the January 12 version of opensmtpd-extras too old for my purposes?

Refreshing to see a project where the documentation surges ahead of the release
rather than lagging behind.

If the service is free, you're the product.

Re: Spot of bother with send to lmtp

[Steve Conrad]

Got it sorted now. 
Thanks for the help.

Upgrade to latest opensmtpd-extras
Change 'listen on all' to 'listen on egress'
Otherwise 'listen on lo0' is in the way


If the service is free, you're the product.

Re: Spot of bother with send to lmtp

[Steve Conrad]

Thanks for sorting that out for me.

Spot of bother with send to lmtp

[Steve Conrad]

Having a spot of bother setting up some virtual domains using the  excellent 
faq at https://opensmtpd.org/faq/example1.html a guide. 

Despite my best efforts to follow the guide, smtpd complains of two syntax 
errors in the config file and declines to start.

The offending lines are the ones involving sending to lmtp, one of which is 
listed below:

accept from any for domain  virtual  deliver to lmtp 
"/var/dovecot/lmtp" rcpt-to

If this is any different from the example, it's not jumping out at me. Has the 
syntax for 'lmtp ... rcpt-to' changed recently?

Running OpenBSD 5.8 amd64 on a digital ocean droplet. Thanks in advance. This 
has been surprisingly easy going for learning a new MTA.
If the service is free, you're the product.
