Hi group,
I intend to package the Cygwin version of Sendmail, version 8.14.9.
category: Mail

m4 procmail tcp_wrappers cyrus-sasl cygrunsrv
sdesc: "The Mail Transfer Agent (mail server)"
ldesc: "General purpose internetwork email routing facility that supports many
kinds
of mail-transfer and delivery methods, including SMTP, SMTPS (STARTTLS),
SMTPA
(AUTH) used for email transport over the internet."
I've implementented the "alternatives" mechanism, so it can be installed
alongside
other Mail Transfer Agents, such as Exim, Postfix or ssmtp.
Please handle also the following man pages via "alternatives":
mailq(1), newaliases(1), aliases(5), sendmail(8).
These definitely will be in conflict with upcoming postfix package. Use
e.g. aliases.sendmail.5.gz as the real filename (as done on Fedora).
See also https://cygwin.com/ml/cygwin-apps/2014-10/msg00010.html and its
attachment.
Is it possible for the Postfix package to not override the 'sendmail' man page?
That
way one can compare the two programs without having to switch like this:
/usr/sbin/alternatives --set mta /usr/sbin/postfix
man sendmail
/usr/sbin/alternatives --set mta /usr/libexec/sendmail
man sendmail
Not needed, because both man pages would be still accessible via 'man
sendmail.sendmail' and 'man sendmail.postfix'.
The /usr/bin/postfix-config script will link sendmail1.gz ->
sendmail.postfix.1.gz via alternatives because then the user has then
*decided* to run postfix as an MTA.
The /etc/postinstall/postfix.sh script will only copy the
/etc/defaults/etc/postfix files (no alternatives, no user/group
creation, no service installation).
Further suggestions:
The following should IMO never be done in a postinstall script:
- Creation of user and group accounts.
- Installation of services.
- Setting alternatives to manual mode (/usr/sbin/alternatives --set ...)
Please consider moving the above to the sendmail-config script.
All steps in postinstall are necessary for running Sendmail.
Note that the above steps are re-done on each package update.
The installation of sendmail does not imply that the user wants to run
it immediately.
The sendmail-config
script contains steps where user-intervention is needed.
An MTA typically cannot be run without some manual local configuration.
Then it IMO does not make sense to do intrusive changes like creation of
Windows user and group creation early in an unattended postinstall script.
I'll move the '--set' instruction to the 'sendmail-config' script.
I will provide a pre-remove script that rolls back user-creation and
service-installation.
In /etc/preremove?
Note that this script is also run on each package update.
- Remove formatted man pages in /usr/share/man/cat*, add troff versions
in /usr/share/man/man*.
I will comply, but consider the following. Making man pages smear lines of text
across the entire width of the screen makes the text unreadable and the layout
ugly,
especially with the omnipresent wide-screen displays nowadays.
I disagree.
These formatted man page *with embedded terminal escape sequences* are
useless for non-terminal output (printing, conversion to pdf, ...).
According to Cygwin package search, only the libfltk-devel package
provides formatted man pages, but it also includes the troff versions.
