Forward a copy of each mail to another smtp-server
Hi! Because i have to move from one server to another one (new hardware and new provider) with all domains, i also have to move all emailaccounts to the new server. Because i wan't to move "step by step" i have to think about synchronisation of the email-accounts. My prefered way would be to forward a copy of each incoming mail (old server) to the new server by smtp. Is there a way to do so with postfix ? Thanks a lot! Best regards, Kai.
Postfix sometimes say's "Missing MXA record"
Hi! After moving our mailserver to another machine (with updated debian) our postfix sometimes say's: > I'm sorry to have to inform you that your message could not > be delivered to one or more recipients. It's attached below. > > For further assistance, please send mail to > > If you do so, please include this problem report. You can > delete your own text from the attached returned message. > >The mail system > > : host mail.ourhost.bar[a.b.c.d] said: 554 5.7.7 > Missing MXA record . (in reply to end of DATA command) The configuration is the same than the configuration on the old server. In the logfile find: smtpd: >>> CHECKING RECIPIENT MAPS <<< smtpd: ctable_locate: leave existing entry key recipi...@ourhost.bar smtpd: maps_find: recipient_canonical_maps: recipi...@ourhost.bar: not found smtpd: match_string: ourhost.bar ~? mail.outhost.bar smtpd: match_string: ourhost.bar ~? localhost.outhost.bar smtpd: match_string: ourhost.bar ~? localhost smtpd: match_list_match: ourhost.bar: no match smtpd: maps_find: recipient_canonical_maps: @ourhost.bar: not found smtpd: mail_addr_find: recipi...@ourhost.bar -> (not found) smtpd: maps_find: canonical_maps: recipi...@ourhost.bar: not found smtpd: match_string: ourhost.bar ~? mail.outhost.bar smtpd: match_string: ourhost.bar ~? localhost.outhost.bar smtpd: match_string: ourhost.bar ~? localhost smtpd: match_list_match: ourhost.bar: no match smtpd: maps_find: canonical_maps: @ourhost.bar: not found smtpd: mail_addr_find: recipi...@ourhost.bar -> (not found)smtpd: maps_find: virtual_alias_maps: hash:/etc/postfix/virtualusers(0,lock|fold_fix): recipi...@ourhost.bar = ste...@l smtpd[16682]: mail_addr_find: recipi...@ourhost.bar -> recipi...@localhost smtpd: smtpd_check_rewrite: trying: permit_inet_interfaces smtpd: permit_inet_interfaces: localhost 127.0.0.1 smtpd: before input_transp_cleanup: cleanup flags = enable_header_body_filter enable_automatic_bcc enable_address_mapp smtpd: after input_transp_cleanup: cleanup flags = enable_header_body_filter enable_automatic_bcc enable_address_mappi smtpd: connect to subsystem public/cleanup smtpd: public/cleanup socket: wanted attribute: queue_id smtpd: input attribute name: queue_id smtpd: input attribute value: 521D38B4068 smtpd: public/cleanup socket: wanted attribute: (list terminator) smtpd: input attribute name: (end) smtpd: send attr flags = 178 smtpd: 521D38B4068: client=localhost[127.0.0.1] smtpd: > localhost[127.0.0.1]: 250 2.1.5 Ok Looks ok...but the message never reaches recipi...@outhost.bar. This only sometimes happens (most time the message will reach the client). Thanks for your help. Best regards, Kai.

Hi! Shame on me...problem was'nt postfix. The spamfilter did the mistake (no: The postmaster who configured it...that's me ;). Sorry! Best regards, Kai.
Encrypt attachments
Hi! For a customer i have to implement "on the fly" encryption for attachments. Means: 1) Send Mail to Customer - Postfix receive email by smtp from local sender - Check if Recipient is in DB. If not => Forward message by smtp to customer - If customer is in DB, detach Attachments, create a encrypted zip-Archiv (password comes from db), re-attach it to email and forward it by smtp to customer Is there a place where i can find more informations about doing it or exists there a "ready" solution ? Thanks a lot! Best regards, Kai.
Re: Encrypt attachments
Hi Andreas, That's why e-mail encryption (S/MIME, PGP) was invented for. Why reinvent the wheel? You are right...and not ;) Problem: If we use for example gpg rhe !other side! also have to use gpg and needs to have a key infrastructure implemented. Most of the "customer customers" don't have very much "computer skills" to realize that kind of things. They can use for example Winzip but nothing moreso i seek for "the middle course" beweeen security <-> usibility. But maybe i'am wrong ? Thanks!
