Sendmail client multiple MX
Hi I'got a problem with sendmail on OpenBSD 4.1 It seems that the sendmail smtp client only try 2 mx for a domain with 4 mx with the same priority (e.g. aol.com) ; DiG 9.3.4 mx aol.com ;; global options: printcmd ;; Got answer: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 60021 ;; flags: qr aa; QUERY: 1, ANSWER: 4, AUTHORITY: 4, ADDITIONAL: 18 ;; QUESTION SECTION: ;aol.com. IN MX ;; ANSWER SECTION: aol.com.3600IN MX 15 mailin-04.mx.aol.com. aol.com.3600IN MX 15 mailin-01.mx.aol.com. aol.com.3600IN MX 15 mailin-02.mx.aol.com. aol.com.3600IN MX 15 mailin-03.mx.aol.com. Is it possible to configure sendmail to connect to all the mx ? Thanks in advance

A few more boxes that you forgot about: $ dig mailin-01.mx.aol.com +short 64.12.137.184 64.12.137.249 205.188.158.121 205.188.159.57 $ dig mailin-02.mx.aol.com +short 64.12.137.89 64.12.137.168 205.188.155.89 205.188.157.25 $ dig mailin-03.mx.aol.com +short 64.12.138.120 64.12.138.153 205.188.157.217 $ dig mailin-04.mx.aol.com +short 205.188.159.216 64.12.138.57 64.12.138.88 Depending on the config, Sendmail should try all of the above IPs until it delivers mail.
