re-alpine can be configured to use different SMTP-servers for different roles/accounts.
The user should also be able to instead invoke sendmail or msmtp with custom options on a per role basis. Currently the value for "Sendmail Path" is static. Meaning it is not possible to dynamically invoke sendmail/msmtp with different command-line options.
This makes it difficult to use msmtp/sendmail with more than one account.
The way I would like to set the Sendmail Path:
1. Go to the config-menue of a role
2. Decide whether you want to directly talk to an SMTP-server or use sendmail
3. In case sendmail is selected have an input-field available that overwrites the value of "Sendmail Path"
How it works with just one account:
Set "Sendmail Path" to:
/usr/bin/msmtp -a example -f firstname.lastname@example.org -t
It would be nice to change the -a and the -f option depending on what role is used for composing.
There is a workaround that I described on my blog (Section "Sending mail with msmtp") but it shouldn't be msmtp's job to guess which account the user wants to use.
