Re: [Courier-imap] Something New: DNS failure messages or "network down" error, yet neither are true
Greg Pfister writes: « HTML content follows » Hi Sam, soft error on the domain. The Debian package "courier-mta-ssl is a transitional package and can be ignored. This system is not new, but years old (more than 5). Nothing recently been done to it other than fail2ban. However, I've checked both with and without fail2ban services - no affect. Before I posted, I checked mx and A record existence and could access hosted server from telnet - from the same system as Courier. Like I wrote before, this was observed before due to broken IPv6 in either the authoritative, intermediate, or caching nameservers. Courier does lookups even on IPv4-only hosts; and there was a change in 1.0.10 to ignore softfails for lookups if the A lookup succeeded. Before 1.0.10 the only option is to rebuild Courier using --without-ipv6 pgpDZ8lbB7wIP.pgp Description: PGP signature ___ Courier-imap mailing list Courier-imap@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-imap

Re: [Courier-imap] Something New: DNS failure messages or "network down" error, yet neither are true
Hi Guys, The problem has been resolved. It was an upstream DNS server problem. Messages queue is processing as it should. No more soft errors on testmxlookup.
