MAILFROM option broken between 1.6.1 and 1.7.0

[djsissom]

I'm using postfix to route outgoing email from a cronie crontab entry to an Apple iCloud+ SMTP server, which requires the FROM address to be on the approved list in order to send mail.

In my (root) crontab, I've set the appropriate MAILFROM address: MAILFROM='admin@example.com'

After updating cronie to 1.7.0, the journalctl entry for postfix after the cron job outputs shows: postfix/qmgr[887]: 1BC705E2030: from=<>, size=782, nrcpt=1 (queue active)

Downgrading cronie to 1.5.7 gives the expected result, and I receive the email: postfix/qmgr[887]: 0531D5E2030: from=<admin@example.com>, size=766, nrcpt=1 (queue active)

My other server is still running version 1.6.1, and that also is still working correctly, so the regression seems to have happened somewhere between 1.6.1 and 1.7.0.

Git-diffing the two commits, there seem to be a couple of places where "mailfrom" is touched between releases, notably in anacron/runjob.c and src/do_command.c.

Do you see this for both cron based and anacron based jobs or just for one of these?

[t8m]

Hmm... actually this was an intentional change from https://github.com/cronie-crond/cronie/pull/118

[t8m]

I assume we could make this optional.

[djsissom]

I get the reasoning behind #118, but if I'm understanding correctly what's happening on my end, now even explicitly setting MAILFROM to a valid address in the crontab results in outgoing mail being rejected from the relay because of the missing FROM header.

I should be able to downgrade to 1.5.7 for the time being until fixed.

Can you please try applying 3428028e6df0a1e9b2efa1cb52b2722f790d9741 4e8c767efb1bea03da465fee29641b65da1246eb c640f4f39e5c20995e960e4b954cd0574a96c028 to see if that works for you?

[djsissom]

Yes, perfect! That works for me as expected and makes the Apple servers happy again.

Thanks for the quick attention!

Hi, may I know when there will be a release with this fix? As the MAILFROM doesn't work in 1.7.0, this fix is quite necessary. Thanks a lot.

[t8m]

I've done a new release now.

Thank you! :tada:
