Recent releases
- 09 Jan 2010 08:08
Changes: This version fixed a problem where some certificate authorities do not properly check the requests they are signing and hence allow spoofing via an embedded NUL in the CN entry. A workaround for a Linux resolver problem has been added to avoid core dumps. A bug where the value of headers, e.g., Precedence, Content-Type, et.al., was not extracted correctly thus preventing them from being recognized properly was fixed. An erroneous reduction of the length limitation on a return path was fixed.

Changes: The MTA accessed storage after it free()d it. This was a regression introduced in 8.14.2. The libmilter state engine did not deal correctly with milters that requested the omission of protocol steps during the negotiation callback.
- 02 Nov 2007 02:48
Changes: This release fixes some problems. For example, fixes were made for a bug in the milter function smfi_chgfrom() which could cause the loss of a message body, the handling of queued messages with 8 bit characters in From: or To: header which could be "mistaken" for internal control characters during a queue run and trigger various consistency checks, and the handling of lines longer than MAXLINE-1 characters in certain cases.
- 05 Apr 2007 10:59
Changes: If a milter rejected a recipient, the MTA still kept it in its list of recipients, and delivered to it if the transaction was accepted. The new DaemonPortOptions that begin with a lower case character can now be set.
- 04 Apr 2007 14:07
Changes: Headers are 8-bit "transparent" and the milter API has been extended.

Recent commentsSendmail in RedHat 6.2
I'm new in Linux, and I'd like to know if anyone can help me with a problem.
I'd like to know how can I control the size of the emails for each user or group of users. Sendmail.cf as a command that we can control the maximum size (in and out). Is it possible to have it per user (eg. user001: 1000kb; user002: 200kb).
Thanks in advance.

Say people who don't know better alternatives.
LDAP Documentation
I have a section on integration of sendmail with LDAP (specifically OpenLDAP) in my LDAP presentation.
ldapv3.pdf (ftp://kalamazoolinux.org/pub/pdf/ldapv3.pdf) hosted by the Kalamazoo Linux Users Group (www.kalamazoolinux.org/). (Kalamazoo, Mi. USA)
Access file limitation
Sendmail when run in conjunction with popauthd scripts which automatically update the access (usually /etc/mail/access) automatically, sendmail seems to fill up a buffer or something and no longer reads from access file and rejects everyone relaying denied.
This is a problem I experienced once my access file get's apx 5000 lines large. Anyone else?
