That then sounds like talking to their support and eventually reconsidering your position to 1blu or gmail. You are definitivly not the only one having problems with mail from or to gmail accounts.

If you do that with a selector under the unixarea.de domain, you have to add the corresponding key in the zone. I would assume you can do that via the interface of 1blu.de Alternatively dkim can be implemented at the 1blu.de MTA, which in turn is solely at their discretion. - Same for a DMARC-entry. This would make most sense when you enable DNSSEC for the unixarea.de domain. Check here: https://dnsviz.net/d/unixarea.de/dnssec/ I would assume you can do that via the interface of 1blu.de.

Something similiar, just with procmail/formail: You need Gnu date for this, sorry non-Posix features used. { #time in seconds since the epoch (to be rethought before Jan 19 2038 03:14:08) :0 hi * ^Date:[ ]*(...?, )?\/[^,]*$ # this blank contains a space and a tab, and yes, there are strange date: header out there DATE=| date -d "$MATCH" +%s # catch unparsable/missing dates :0 hi * DATE ?? ^$ DATE=| echo "0" :0 fwhi | formail -i "Date: `TZ=America/Los_Angeles date -d @$DATE -R`" } Just leave out TZ= to get your default timezone HTH, Joerg signature.asc Description: PGP signature

That sounds like you want to have a MTA which does queuing and is triggered by whatever (e.g. internet up) to run queues. sendmail can do that, but also exim, postfix,... uucp, too, for a honorable mention. Not sure if nullmailer does queueing. Bye, Joerg signature.asc Description: PGP signature

Re: mutt and not really read only mailboxes
On Thu, Aug 23, 2012 at 01:49:07PM -0500, Derek Martin wrote: Not really. You can't really fix this. If mutt can't lock the folder then other processes (e.g. the MDA) can change the contents out from under Mutt while it's reading the file, potentially resulting in an inconsistent state. Actually the MTA just appends to the file. It can get messy when a second mutt or so with write access changes the mbox more arbitrarily. But, there's probably not really any good reason to read mail from a read-only NFS mount, so just stop doing that, and your problem should go away. The main reason is to see non-text without IO-redirection. Readonly because I liked to try with least possible privileges. - Dot-locking is (or at least was, and may still be) unreliable over NFS - POSIX locking (i.e. fctnl()) is not. I know. From reading the source, I am more puzzled what is really happening. The mx_lock_file function tries fcntl first, and only if this fails tries dotlocking. fcntl()-locking works at least once upon startup. I'll do more debugging to get more insight into this.

mutt and not really read only mailboxes
Hello, I have a setup where my MTA delivers mail to an mbox file, which then is in turn exported via nfs read only to the client where mutt is running. Main purpose of this construction is viewing certain attachments. While all this works fine the first time mutt is started, after a while there is the situation that new mail arrives, however the mutt instance with the read only filesystem does not notice. Would it be possible to make mutt check for changes to the mailbox, even when this is located on a read-only filesystem? Bye, Joerg signature.asc Description: Digital signature

I need to correct myself: With an strace, I see that mutt does a stat() on the mbox file with every keypress while in the index screen, the stat() returns the proper size and times. However, it then forks the mutt_dotlock process, which fails because it the filesystem with the mbox is readonly. The source from mbox.c reads if (mbox_lock_mailbox (ctx, 0, 0) == -1) { mutt_unblock_signals (); /* we couldn't lock the mailbox, but nothing serious happened: * probably the new mail arrived: no reason to wait till we can * parse it: we'll get it on the next pass */ return (M_LOCKED); } Needless to say the assumption expressed in the comments does not hold. Would this finding justify a bug report? A solution might be to add a special case for following readonly mailboxes (both read only file and file on read only filesystem), The rest of the logic in the check_mailbox function is correct here. The current workaround of exiting and restarting mutt seems quite cumbersome to me. Bye, Joerg signature.asc Description: Digital signature
mailbox updates not followed on ro-nfs
Hello, I am wondering if it is possible to tell mutt to check for updates in mailboxes that are on a read-only nfs share. I have mutt 1.5.21-5 (debian testing) on machines which mounts /var/mail/ readonly via nfs4 from the server where /var/mail/mbox is updated. mutt detects that the mailbox is readonly and prevents any changes to it. However, it does not detect when there are changes by others to the mailbox, especially when new mail arrives. Is it possible to tell mutt somehow to regularly check for updates even for the read-only mailboxes? Bye, Joerg signature.asc Description: Digital signature
