Hi,
we seem to have a problem with our list "lwip-users". Up to september 26th, the mails came in as to "lwip-us...@nongnu.org".
However, since september 29th, they have an additional "reply-to" header, which sends responses to "liwp-us...@gnu.org".
Now sending a response, I get an error message: lwip-us...@gnu.org: SMTP error from remote server for RCPT TO command, host: eggs.gnu.org (208.118.235.92) reason: 550-Callout verification failed: 550 550 Unrouteable address Is this a problem with the malining lists? Or anything I have done wrong? Thanks, Simon
