Feature: Add additional ignored flags to sendmail

[lucassabreu]

sendmail is sometimes used for sending the output of a crontab runtime.

those crontab might send 3 non-mapped options

• -F - name of the sender
• -B - configuration bits
• -e - delivery error behaviour

to not conflict with cron systems i mapped those flags so they don't prevent the e-mail from being sent to mailpit

Thanks for this @lucassabreu. I'm really curious about the -e flag, as I cannot find any reference to a sendmail client which supports that. Are you able to provide me with a reference for one that does?

[lucassabreu]

i was not able to find the link that i found before, not this one from oracle shows it:
https://docs.oracle.com/cd/E19504-01/802-5827/6i9idjvnm/index.html

Awesome, thank you. So is -e something you actually need for your setup, or is this something that you just came across and thought to add? The only reason I ask is that there are probably 50 different flags possible if you add up all the different sendmail clients, so I'd prefer to just stick to ones that people need.

[lucassabreu]

so i added those because of this error that appears, and them the crontab does not work calling it.

if we could just ignore all non-mapped flag, then it would work too.

These additional sendmail flags have been included in v1.12.2. Thank you for your contribution, and please let me know if this solves your cron issue?
