should NET_EHOSTNOTFOUND map to EX_TEMPFAIL?

[greg-minshall]

hi.

currently net_open_socket() in net.c, if getaddrinfo(3) returns non-zero, returns NET_EHOSTNOTFOUND, which, iiuc, gets mapped to an msmtp exit status of EX_NOHOST.

i wonder if get addrinfo returns, e.g., EAI_AGAIN, maybe net_open_socket() should instead return something that would map to EX_TEMPFAIL, the same as when trying to connect to the host fails (i.e., return NET_ECONNECT).

i'm guessing this issue of different sendmail return codes, when to pass which, how to respond to which, is, umm, complicated.

cheers.

Yes, it's complicated ;) But in this case you are right and I think the best we can do is fix these things as they come up. This is done now (the patch will show up on the github mirror in a few hours).
