net_get_canonical_hostname simply calls gethostname() from glibc, and that function just calls uname(); it doesn't appear possible to change the source IP in glibc without using a standalone resolver library.

I would have thought binding to specific ip/alias/interface in case of multiple being present was already in msmtp. Thanks for bringing up this feature. Aren't there functions in the resolver libs for that? (Here I see one for switching to TCP connections but so far not for setting src ip. If not, this should be ticketed upstream as feature request in linux/bsd.) You could also bind a named/unbound instance and point the resolver there. _______________________________________________ msmtp-users mailing list msmtp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/msmtp-users ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
