1 Department move to LDC? Issue list /GH, rev. 2b

2 Issue categories A: ing through LDC Exchange B: setup and protocols C: Mailing lists D: Calendar E: LDC Service level F: AlternaLve solulons G: Next steps

3 A: ing through LDC Exchange A1-3: Delays, out- or- order, lost s Anecdotal reports from EIT. Need test and stalslcs. A4: ARachments Anecdotal problem report from LB sending to kansli LTH. Need test. Max size 100 MB. A5: addresses By default only In special cases old aliases might be supported, good arguments will be needed. A6: SAM s Will work. Details not yet sorted out. A7: Sendmail Should work inside LU network Need to look into machines sending to A8: Can have separate pwd to (from LUCAT)? No. A9: UPS Supervisor. No problem. A10: Mail from test servers, e.g. From Jenkins to mailinglist. Will need to use open mailinglist, or feature request to LDC.

4 B: setup and protocols B1: IMAP for reading ? Can be used from both inside and outside LU on all placorms B2: SMTP for sending ? Works from inside LU. From outside, need VPN, ssh- tunnel, or via Google. B3: VPN Works on windows. Should work on Mac, but slll some issues. Does not work on Linux currently, but LN will look into it. Phones? B4: Exchange Supported by Microsoe Outlook.exe and Apple Mail.app. Supported by Iphone and Android. Can be used by Thunderbird via plugin ExQuilla (small cost), or gateway DavMail (open source). Supports reading and sending most places (ports may be blocked at some companies). B5: Exchange/Thunderbird PM has table over tested placorms, see later slide. Upgrading issue: what happens at exchange/thunderbird/os upgrades. B6: Exchange sehngs for phones LDC requires access to complete phone to support wiping it if stolen. B7: Exchange webmail BeRer than current But cannot be the main alternalve.

5 B8: Forwarding Via your LUCAT sehngs. B9: VacaLon Via WebMail interface B10: Filtering to mailboxes BeRer/simpler than procmail B11: Spam filtering B: setup, cont. Will lose current spam filtering anyway (PerF) Anecdotal problems from EIT, google groups caught in filter B12: Submit protocol from MUA to MTA B13: Use Google SMTP(s)? Works according to KN and JJ. But according to LÅ a special DNS record needs to be added under cs.lth.se, to avoid s being flagged as potenlal spam. Use private gmail account for sehng up. Sender and Reply- to can be set up to official LU address. Need to test: Can the ulund.org address be used for people without gmail account? Can we get LDC to add the special DNS record? B14: Local CS SMTP server? Not feasible. Would require authenlcalon towards LUCAT. B15: Ask LDC to turn on SMTP(s)? Not feasible currently. In the long run, could lobby via IT- kontoret.

Man får då garan- terat en adress utanför LU, men kan sitta kvar på sitt kontor. Linux1 gick inte att testa på detta sätt."

7 C: Mailing lists C0: Two kinds of mailing lists Exchange, seems to only support LU users LDC lists, see hrp://listserver.lu.se Probably the one to use C1- C2: Problems with Exchange lists Anecdotal problems reported by EIT and LB. Needs to be checked. C3: Comparison between LDC lists and Mailman. Works for me (GH). Needs to be examined in more detail. Different users have different parerns. Is the support sufficient? LDC developed this. We can send feature requests. Archiving?? C4: Local Mailman at CS? Not feasible. Would require our own domain, etc. C5: Naming mailing lists? Can we name Exchange/LDC mailinglists in anyway we like? E.g., or

8 D: Calendar D1: Does Exchange run an open Protocol? Tested with Apple s ical.app. Not tested with anything else. Needs to be inveslgated further. To what level is integralon with google calendar possible? D2: AlternaLve solulons for common calendar? JJ: Google calendar might be a possibility

9 E: LDC Service Level E1: Service- mindedness to users? Problems reported at EIT PM reports improvements E2: CollaboraLon with our technical staff? New system at LDC to let our tech staff see all CS issues. E3: AcLons if LDC does not deliver Need to be sorted out at head of dept level

10 F: AlternaLves F1: Business as usual (CS solulon) Too risky. Not an oplon. F2: LDC Under inveslgalon. No extra cost (except for own Lme when there are problems). Solves general risk problem. F3: ConLnue at CS but with more personnel Expensive. F4: CooperaLon with neighbor depts? Would give berer redundancy than F3 Might be difficult to agree on setup and setups might diverge. F5: Google KN claims works right away and at no extra cost. Not viable from LU point of view. Need nalonal solulon.

11 G: Next Steps Jesper Ö (TB), Jörn (TB), Linus (Mint), will test using PM s LDC test account. Lars B test TB on Mac? Everybody: Think about addilonal issues Tech group: ConLnue teslng and sorlng out issues
