MeTA1 1.1.Alpha21.0

Last Update 2025-01-27

[Main] [Release] [Documentation] [Misc] [PGP]

A patch (sig) is available which addresses the following problem: smar might have skipped an MX record in the following situation:

c.tld   CNAME   h.tld
h.tld   MX 10   h.tld
h.tld   MX 10   n.tld

That is, when an address is a CNAME which resolves to a hostname which has itself as MX and there is another MX, then the IP(s) of the hostname would not have been used.

MeTA1 Source Code

MeTA1 1.1.Alpha21.0 is available for testing. It addresses configure problems on systems with some strict compiler options (see below), checks whether options enabled via --enable-XYZ actually can work, adds some new features, and fixes some minor problems.

The source code distribution and the PGP signature are available at:

Changes compared to MeTA1 1.1.Alpha20.1

2025-01-12 Note: on some systems someone has decided that fgrep and egrep must generate warnings on stderr. This will break some tests. Just override the $#%^! decision by using something like: alias fgrep="grep -F" alias egrep="grep -E"
2025-01-11 For some compilers the option -Wno-incompatible-pointer-types is required. This is especially true during configuration, hence something like this CFLAGS="-Wno-incompatible-pointer-types" ../meta1-$VERSION/configure -C should be used. A similar problem currently requires to add -D_FORTIFY_SOURCE=0 -D_USE_FORTIFY_LEVEL=0 to CFLAGS on some systems (e.g., those which enable FORTIFY by default).
2025-01-10 statethreads has been updated to handle newer Linux versions.
2025-01-07 A new tag mxbadname has been added to block senders by MX. For exmaple, all of these have the same MXs (at least when this was written) 10 mx1.emailsrvr.com. 20 mx2.emailsrvr.com. Hence an entry like this mxbadname:.emailsrvr.com. error:550 5.7.1 no mail from domains hosted by emailsrvr.com. blocks all those senders.
2024-12-14 cdb map: return the correct error code when a result is too large (for the supplied buffer).
2024-12-14 To select the cdb map type by default instead of hash (bdb) use -DSM_MAP_DFLT=2
2024-11-17 Added partial support for LIMITS extension (RFC9422) if FFR_LIMITS is used. smtps: MAILMAX (transactions_max) and RCPTMAX (recipients_per_transaction_max) are shown if configured. smtpc: if RCPTDOMAINMAX=1 is listed, then smtpc will send only RCPTs with the same domain as the first one of a transaction.
2024-11-12 smtpc: enhanced logging for I/O errors during various stages.
2024-11-11 Fix a regression when FFR_CERT_PINNING is used - the code almost always complained about a cert having changed even if that was not the case.
2024-10-23 Builtin DANE support has modified so it works for LibreSSL >= 3.6.0 (which changed the verification callback algorithm).
2024-08-31 If --enable-{TLS,SASL,DKIM} is used for configure but required files or functions are not available, fail during configure.
2024-08-25 If --enable-tinycdb is used for configure but the required tinycdb files are not available, fail during configure.
