Re: [msmtp-users] connection test(s) for msmtpq

Hi Bryan,

Apologies for the delay. I don't know whether or not my previous reply
got through to you ; it certainly hasn't to the list (mutt has begun
acting up on list dialogues for me recently).

Thanks for the reply. To be redundant (if necessary), your net
connection test is interesting and I wonder whether of not it can be
scripted. That is, can Bash do what you describe or does it require a
C program ? If either is possible would you be willing to send me
sample code ?

The next version of the queue script will have defeatable connection
testing.

Sending this is a kludge until I get mutt fixed ; hope it makes it.

Best,

Chris

There is probably a better way, but currently to get a 'Send Success' or 'Send Failed' result from msmtp I redirect Standard Out to a file and then check the file length, this mostly works well but fails because the msmtp 'net connection' test doesn't seem to return an error message if there is no internet connection.  So I use my own net connection test before I call msmtp, I just try to open a socket to an external system (email or web) using a string address that has to passed through a DNS server, this testes both the internet connection and that there is a usable DNS server.  I set a timeout in setsockopt using SO_SNDTIMEO.  It seems to work.  So for me, I would be quite happy if msmtp doesn't do an internet test.  I am running msmtp on an embedded linux computer,I don't think it caches DNS requsts.
