4.19 SMTP problems fixed in this release

The following section describes SMTP problems fixed in this release.

4.19.1 Anti spam for unresolvable-domains and unqualified-senders

TCPIP SMTP antispam works correctly for:
- Accept-Unresolvable-Domains: FALSE
- Accept-Unqualified-Senders: FALSE

But, if on the BIND server, a MX wildcard record of type [ *.ind.hp.com. IN MX 10 munar ] with munar having a "A" record defined, anti spam for Unresolvable-Domains and Unqualified-Senders stops working.

Removing the *.ind.hp.com MX record makes the system to work as expected, that is, the system refuses the mail with unresolvable domain.

Solution:

This problem is fixed in this release.

4.19.2 SMTP fails to receive mails

Problem:

Although, the mails sent to the local or remote host (not running TCPIP 5.7) work, SMTP fails to receive mails sent from a remote host. On replying back to a mail sent from a TCPIP 5.7 system, the mail bounces.

Solution:

This problem is corrected in this release.

4.19.3 Large number of recipients in the TO field

Problem:

Having a large number of recipients in the TO field of an arriving SMTP message could lead to corrupt header lines.

Solution:

This problem is corrected in this release.

4.19.4 VMS MAIL does not support lines longer than 255 characters and mixed case headers

Problem:

• VMS MAIL does not support lines longer than 255 characters. Long header lines are becoming increasingly common in the modern Internet. While fetching such messages, the IMAP server may return some headers in the body part of the mail, causing it to appear corrupted to the client.
• IMAP has trouble fetching mails with lowercase or mixed case RFC headers.

Solution:

This problem is corrected in this release.

4.19.5 SMTP server fails to deliver mail

Problem:

The SMTP server fails to deliver mail when the domain name is a combination of letters and numbers. As per RFC, the domain name can be any combination of numbers and letters.

Solution:

This problem is corrected in this release.

4.19.6 SMTP distribution list filenames fails to form properly

Problem:

SMTP distribution list filenames are not always formed properly, and it is not possible to specify a location other than TCPIP$SMTP_COMMON: to contain *.DIS files.

Solution:

This problem is corrected in this release.

4.19.7 TCPIP$SMTP_FROM logical affects the SMTP Return-Path header

Problem:

The TCPIP$SMTP_FROM logical affects the SMTP Return-Path header when defined. The Return-Path must reflect the contents of the logical name, as it did prior to TCPIP V5.6, with no need to encapsulate the value within angle brackets.

Solution:

This problem is corrected in this release.

4.19.8 Adding Persistent-Server displays an error message

Problem:

When you add the "Persistent-Server" field in the TCPIP$SMTP.CONF file and restart SMTP, TCP/IP displays the following error:

unknown configuration field; Persistent-Server has been ignored. 

Solution:

This problem is corrected in this release.

Problem:

If the total number of BG or MBA devices exceeds 5000, TCPIP$HR_MIB process consumes excessive CPU time and leads to sluggish performance.

Solution:

A new logical, TCPIP$SNMP_SCAN_ALLDEV, is included. If TCPIP$SNMP_SCAN_ALLDEV is defined, the entire set of devices will be scanned. If the logical is not defined then only the following devices will be scanned:

• Disk
• Tape
• Communication device
• Terminal
• Line printer
• Work stations
• General audio
• Bus
• General video
• DEC voice products

Solution:

This problem is fixed in this release.

4.21.6 SSH idle-timeout counter fails to reset

Although the SSH server sends messages to the client within the configured idle-timeout period, the SSH client would still timeout. Hence, the SSH idle-timeout counter would fail to reset if a message was received from the server.

Solution:

This problem is fixed in this release.

4.21.7 SFTP client converts filenames to uppercase

Problem:

On ODS-5 disks, when connecting to a UNIX system using the get command, the SFTP client converts filenames to uppercase.

Solution:

This problem is corrected in this release.

4.21.8 SFTP "PUT" command fails on Windows server

Problem:

When copying a file using the PUT command from an OpenVMS to a Windows 2003 PC using WS_FTP Server 7.1 from IPSWITCH.COM, SSH_FILEXFER_ATTR_PERMISSIONS error is returned. A file header is created, but no data is placed in the file. Both binary transfers and ascii stream_lf transfers fail.

Solution:

This problem is corrected in this release.

4.21.9 SFTP "CD SYS$LOGIN" fails

Problem:

In an SFTP from an OpenVMS system, the user cannot navigate to the home directory using "cd sys$login" or "cd /" or "cd ~". When such an operation is attempted, the user is either directed to a wrong directory (which in most cases is the ssh's home directory) in case of a privileged user or gets a "CD FAILED" error in case of an unprivileged user.

Solution:

This problem is corrected in this release.

4.21.10 SFTP process becomes CPU-bound when using CHROOT

Problem:

SFTP process becomes CPU bound when using CHROOT. If most of the SFTP processes become CPU-bound, it can render the OpenVMS system unusable with Denial of Service.

Solution:

This problem is corrected in this release.

4.21.11 ls * .txt does not display the list of files

Problem:

The ls * .txt command in SFTP command fails to display the list of files in the current working directory and exits with an ACCVIO.

Solution:

This problem is corrected in this release.

4.21.12 Copy fails with wildcard (*) character

Problem:

SCP copy fails when the command is entered with wildcard (*) character. The copy command also fails when entered with percentage sign (%).

Solution:

This problem is corrected in this release.

4.21.13 ACCVIO on non-existent user

Problem:

The SSH server fails with an ACCVIO on non-existent user.

Solution:

This problem is corrected in this release.

4.21.14 mget *.lis does not work

Problem:

Solution:

This problem is corrected in this release.

4.21.15 ls -l fails to work

Problem:

The ls -l command in SFTP does not work.

Solution:

This problem is corrected in this release.

4.21.16 ACCVIO if identifier not the same as the username

Problem:

An ACCVIO error occurs in the SSH client if the identifier name for the current UIC is not the same as the username.

Solution:

To keep compatibility with older versions, the logical name, TCPIP$SSH_ALLOW_IDENT_MISMATCH must be assigned in the system table to enable the new behavior. If not assigned, or if assigned with numeric value 0, the code behaves as in previous versions.

4.21.17 Wildcard ("*") processing on "ls"

Problem:

Within SFTP, wildcard ("*") processing does not work properly on ls or, if the target file already exists, on mget .

Solution:

This problem is corrected in this release.

4.21.18 Entering an extra <CR>

Problem:

Within SFTP, it is necessary to enter an extra <CR> after pressing <CTRL/Z>, <CTRL/Y>, or <CTRL/C>. Also, display of the resulting messages such as "** Interrupt **" is not consistent with other TCPIP components, nor with longstanding VMS usage.

Solution:

A new logical name, TCPIP$SSH_SFTP_SUPPRESS_EXIT_MESSAGES, is available to suppress display of the following messages:

     - CTRL/Z -> ** Exit ** 
     - CTRL/Y -> ** Interrupt ** 
     - CTRL/C -> ** Cancel ** 

It is effective if the logical name is defined at the system level (/SYSTEM) with any value except 0.
