[csw-users] Sendmail - File too large

[Owen Eng]

Hi,

We have been using CSWsendmail 8.14.2,REV=2007.12.17 flawlessly until now. One of our mailboxes has all its emails stuck in the mail queue and there are these messages in /var/log/syslog

Jun 10 11:25:34 mayosoyva sm-mta[28750]: [ID 801593 mail.info] p5ADsY8f027775: to=<xxx at xxx.com>, delay=01:30:54, xdelay=00:00:00, mailer=local, pri=10304087, relay=local, dsn=4.2.0, stat=Deferred: 450 4.2.0 /var/mail/xxx: File too large

The server is using UFS in / and ZFS in /export. Here are some system details that might help.

I believe it is failing because the mailbox "/var/mail/xxx" is 2GB. In fact, it works if I remove it and let it recreate a new one. Is there a max file size limit in play somewhere that I am not aware of?

Can anyone help me solve this problem?

Thanks in advance.
Owen
