Dear all, Sorry if the question is off-topic, hopefully not completely though.
I am wondering what's the best way to use different SMTP servers to send mails, depending on which e-mail account I am currently using (the From address). I do realise that the two things (the SMTP server used to send an e-mail on the one hand, and the e-mail address in the From header of that mail on the other hand) are not necessarily related and that's actually my current setting: I use the same SMTP server, with authentication, no matter where I am and no matter which e-mail address there is in the From header of the e-ml am sending. My question is: can that be changed and, if yes, how. So far I use exim4 to send e-mails but I didn't see a way to specify which "smarthost" to use to send e-mails e.g. on the sendmail command line. So, even if I could use mutt send hooks to choose which SMTP configuration to use based on my From address, I don't know how to pass this information to the MTA and I am assuming this should not even happen. One other alternative may be to let mutt send e-mails to SMTP servers itself, directly, without going through sendmail/exim4, but then I am wondering what is going to happen if I try to send an e-mail while my computer is off-line. Am I correct that mutt has no queue or whatsoever that would allow it to defer sending e-mails until the computer is back online, which is exactly what the MTA does? I can't come up with a satisfactory solution and would really appreciate feedback on this topic. Many thanks in advance, Sébastien.
