Fetchmail is a handy tool to move / copy your emails from another email provider.
Lets say you host your own Mailserver and also want to receive your mails from i.e. googlemail. Fetchmail will take them and put it in your own inbox. 

Create the "fetchmailrc" file in the mounted data folder.
It should contain these lines - but you have to adapt it to fit your needs. i.e. your mail address and remove the "keep" if you want to remove the mails in the fetched remote mailbox.

set no syslog
set logfile /data/log/fetchmail.log

set postmaster "fetchmail"

poll imap.gmail.com with proto IMAP
  user '[email protected]' there with password 'yourpassword' is fetchmail here options fetchall ssl keep
  smtphost mail.example.org
  smtpname [email protected]

Hi Patrick,

 

I am curious about a few things...

 

For example, how will this react if the destination server is offline (this is a real case, as the container on host, starts much earlier than the VM that hosts the destination mail server).

Does it retry? Is this configurable?

 

Also, in the destination server, does this actually look like it was sent originally to that server?

 

Also can it be done to work with more than one accounts? (both source and destination)

Seems you never replied to my mail 2 years ago (!) although you periodically visit the forums... but today I write again because fetchmail stopped working and in the logs I keep seeing:

fetchmail: SMTP error: 452 4.3.1 Insufficient system storage

...I have no space issues for my docker folder (it is a folder not a file).

What could be the issue?
