hi, i'm having some probs with sendmail-8.12.11-4.RHEL3.1 and perhaps someone on this list could shed some light. mails larger than 100kb or so are getting stuck at DATA and are sitting idly in /var/spool/clientmqueue but smaller size emails are being sent without probs. /var/log/maillog shows a bunch of timeouts connecting to localhost but the daemon is definitely running on localhost on port 25. iptables is completely down. i'm not exactly sure what has changed with the introduction of the smmsp aside from sendmail running setgid instead of setuid root but i never had any probs with 8.11 or earlier with the default config. i've compiled 8.13 on this same box and have run into the same prob... ugh. in desperation i upgraded to the 2.4.21-27.0.2 kernel and the clientmqueue flushed upon rebooting but now they're starting to choke again. any help would be sincerely appreciated. from /var/log/maillog: Apr 14 00:33:58 testmachine sm-msp-queue[11610]: j3AGmhm2026980: to=postgres, delay=3+14:35:15, xdelay=00:00:00, mailer=relay, pri=8149088, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: Connection timed out with [127.0.0.1] Apr 14 00:33:58 testmachine sm-msp-queue[11610]: j3ACR729002195: to=sysadmin@xxxxxxxxxx,murray@xxxxxxxxxx, ctladdr=postgres (503/503), delay=3+19:06:51, xdelay=0:00:00, mailer=relay, pri=8627790, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: Connection timed out with [127.0.0.1] Apr 14 00:33:58 testmachine sm-msp-queue[11610]: j39Cmfm2025894: to=postgres, delay=4+18:35:17, xdelay=00:00:00, mailer=relay, pri=10558309, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: Connection timed out with [127.0.0.1] Apr 14 00:33:58 testmachine sm-msp-queue[11610]: j398iVPv002644: to=sysadmin@xxxxxxxxxx,murray@xxxxxxxxxx, ctladdr=postgres (503/503), delay=4+22:49:27, xdelay=00:00:00, mailer=relay, pri=10947013, relay=[127.0.0.1], dsn=4.0.0, stat=Deferred: Connection timed out with [127.0.0.1] [root@testmachine root]# sendmail -v -Ac -q Running /var/spool/clientmqueue/j3DMmnm2027088 (sequence 1 of 10) j3DMmnm2027088: locked Running /var/spool/clientmqueue/j3DIYtTH032078 (sequence 2 of 10) sysadmin@xxxxxxxxxx,murray@xxxxxxxxxxxxx Connecting to [127.0.0.1] via relay... 220 testmachine.domain.com ESMTP Sendmail 8.12.11/8.12.11; Thu, 14 Apr 2005 01:27:18 -0700 >>> EHLO testmachine.domain.com 250-testmachine.domain.com Hello localhost.localdomain [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH GSSAPI 250-DELIVERBY 250 HELP >>> MAIL From:<postgres@xxxxxxxxxxxxxxxxxxxxxx> SIZE=186113 AUTH=postgres@xxxxxxxxxxxxxxxxxxxxxx 250 2.1.0 <postgres@xxxxxxxxxxxxxxxxxxxxxx>...
