Dear all, I have been getting smtp timeouts from certain domains (mostly Yahoo) and I at first I thought I had been blocked as mail to 90% of other domains is flowing well (gmail, aol, you name it). It took a lot of time to communicate with Yahoo but they have eventually replied stating that they are not blocking us.
But even a simple "telnet a.mx.mail.yahoo.com 25" times out. We have never had that issue before. If they are not blocking us, what else could I check to be the cause of networking problems? If it matters, I can telnet yahoo.co.uk and yahoo.co.cn (or yahoo.cn I don't remember now) but they seem to be using different MX-s. I am on a FreeBSD 6.3-RELEASE-p1. But this is hardly OS-related issue. We're behind a Dlink DFL 700. Telnet to yahoo works on no machine, whether it is Windows of FreeBSD. Our DSL provider claims the line is OK and there are no issues. The DFL utility has been with us for 2 years or so and seems to be working OK. exim -bV Exim version 4.69 #0 (FreeBSD 6.2) built 03-Jan-2008 07:47:57 Copyright (c) University of Cambridge 2006 Berkeley DB: Sleepycat Software: Berkeley DB 4.2.52: (December 3, 2003) Support for: crypteq iconv() IPv6 use_setclassresources PAM Perl Expand_dlfunc OpenSSL Content_Scanning Old_Demime Experimental_DomainKeys Lookups: lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmnz dnsdb dsearch mysql nis nis0 passwd Authenticators: cram_md5 dovecot plaintext spa Routers: accept dnslookup ipliteral manualroute queryprogram redirect Transports: appendfile/maildir/mailstore/mbx autoreply lmtp pipe smtp Fixed never_users: 0 Size of off_t: 8 Configuration file is /usr/local/etc/exim/configure Many, many thanks for hints how to troubleshoot the problem. -- Zbigniew Szalbot -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
