… for addresses [email protected] and [email protected] The original config option stays, and we still use it for the common case where we have a single separator. The "+" is configured by default. It is optional, just like the new option "LocalpartCatchallSeparators" (plural). When parsing the config file, we combine LocalpartCatchallSeparator and LocalpartCatchallSeparators into a single list LocalpartCatchallSeparatorsEffective, which we use throughout the code.

I have used
+as a local part “tag separator” in e-mail addresses for a long time. But over the years I have encountered several sites that either don’t allow+in e-mail addresses, or that handle such addresses incorrectly by converting the+to a space[1], so I added-as an additionalrecipient_delimiter[2] to my Postfix-based mail setup:Currently Mox supports only one
LocalpartCatchallSeparator, which makes it hard to move my mail setup over (I can manually add destinations for all the ones that currently use-, but…).In other words: it would be nice if Mox supported more than one separator too.
Or maybe an alternative could be to allow wildcard “destinations” like e.g. account+@Domain and account-@Domain (or whatever syntax would work best)?
