Thunderbird 'is not imap4 mail-server'
Mozilla thunderbird with sme7.x imap server sometimes gives this error message, This Mail-server is not a imap4 mail-server
To workaround thunderbirds limitations, increase the ConcurrencyLimitPerIP value
config setprop imap ConcurrencyLimitPerIP 20 config setprop imaps ConcurrencyLimitPerIP 20 signal-event post-upgrade; signal-event reboot
check
config show imap tail -f /var/log/imap/current | tai64nlocal
Spamassassin
Set spamassassin for automatically delete junkmail. You can change the "days" that spamassassin sets to automatically delete junkmail, to delete after two months
db configuration setprop spamassassin MessageRetentionTime 60 signal-event email-update
Keep a copy of all emails
You may need to keep a copy of all emails sent to or from your email server. This may be for legal, or other reasons.
The following instructions will create a new user account (maillog) and forward every email that goes through your SME server to it.
First, log onto the server-manager and create the user maillog
Go to the SME Command Line (logon as root) and issue the following commands:
config setprop qpsmtpd Bcc enabled signal-event email-update
Optionally make the forwarding of the emails invisible to the end user. Without it, there will be an X-Copied-To: header in each email. Run this command before the signal-event
config setprop qpsmtpd BccMode bcc
If you want to view the emails, point your email client at the SME and log on as maillog.
Allow external IMAP mail access
There was a deliberate decision to remove non-SSL protected username/password services from the external interface.
to allow unsecure IMAP access
config setprop imap access public signal-event email-update
But before you do this try to use secure IMAP
fixme: explain how
Set max email size
Restrict the size of email messages that can pass through your mail server
config setprop qmail MaxMessageSize x signal-event email-update
where x is in bytes, eg 6000000 = 6 MB
add the admin user as an administrator for Horde
config setprop horde Administration enabled signal-event email-update
"421 per host concurrency limit reached" when I try to send an email using IMAP
A fix is documented here.
delete double bounce
To stop getting double bounce messages
config setprop qmail DoubleBounceTo devnull signal-event email-update
see a longer explaination here
